Working of a Four Stroke Engine in Hindi with Animation
 
03:28
A four-stroke engine (also known as four cycle) is an internal combustion (IC) engine in which the piston completes four separate strokes while turning a crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: 1. Intake: also known as induction or suction This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. 2. Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage. 3. Combustion: also known as power or ignition This is the start of the second revolution of the four stroke cycle. At this point the crankshaft has completed a full 360 degree revolution. While the piston is at T.D.C. (the end of the compression stroke) the compressed air-fuel mixture is ignited by a spark plug (in a gasoline engine) or by heat generated by high compression (diesel engines), forcefully returning the piston to B.D.C. This stroke produces mechanical work from the engine to turn the crankshaft. 4. Exhaust: also known as outlet. During the exhaust stroke, the piston once again returns from B.D.C. to T.D.C. while the exhaust valve is open. This action expels the spent air-fuel mixture through the exhaust valve.

How Engine Cooling Water System Works - In HINDI
 
07:18
A car engine produces a lot of heat when it is running, and must be cooled continuously to avoid engine damage. Generally this is done by circulating coolant liquid usually water mixed with an antifreeze solution through special cooling passages. A water-cooled engine block and cylinder head have interconnected coolant channels running through them. At the top of the cylinder head all the channels converge to a single outlet. A pump, driven by a pulley and belt from the crankshaft, drives hot coolant out of the engine to the radiator, which is a form of heat exchanger. Unwanted heat is passed from the radiator into the air stream, and the cooled liquid then returns to an inlet at the bottom of the block and flows back into the channels again. Usually the pump sends coolant up through the engine and down through the radiator, taking advantage of the fact that hot water expands, becomes lighter and rises above cool water when heated. Its natural tendency is to flow upwards, and the pump assists circulation. The radiator is linked to the engine by rubber hoses, and has a top and bottom tank connected by a core a bank of many fine tubes. The tubes pass through holes in a stack of thin sheet-metal fins, so that the core has a very large surface area and can lose heat rapidly to the cooler air passing through it.

Renewable and Non-Renewable Energy Resources in Hindi
 
02:48
The difference between renewable and non-renewable resources can be done on the basis of their usage life, carbon emission, quantity available, maintenance cost, environment friendly nature, land area required for installation and much more. The energy resources which cannot be exhausted and can be used again and again are called renewable energy resources. For example solar energy, wind energy, tidal energy and hydroelectric etc. The energy resources which can be exhausted one day and cannot be used repeatedly are called non-renewable energy resources. The example of non-renewable energy resources are coal, petroleum, natural gases etc. 1. The renewable energy resources can be depleted and used again and again. But the non-renewable resources are limited in number and can be depleted one day. 2. The carbon emission in renewable energy resources are very low and prevent global warming. In non renewable resources the carbon emission is large and contributes in global warming. 3.The renewable resources are cheaper and present in unlimited quantity but the non- renewable resources are costlier and present in limited quantity. 4. The life of renewable resources is infinite. In case of non-renewable resources the life is finite. 5. The maintenance cost for the power plant of renewable energy resources is low but it is high in the case of non-renewable energy resources. 6. Solar energy, wind energy, tidal energy and geothermal energy are called as renewable resources. Coal petroleum, natural gas, are called non-renewable resources. The wait is finally over.

What is Flywheel? | How it works? | Hindi with Animation
 
04:33
Flywheel is a circular wheel attached to the crankshaft of the engine that stores the mechanical energy of the engine during power stroke and imparts that stored energy to the preparatory strokes (i.e. suction, compression and exhaust stroke) during the engine working. It is made of steel or cast iron. It is mainly used in the engine and fabricating machines like rolling mills, punching machines, shear machines, presses etc. Why We Need Flywheel? In four stroke engine we have four strokes i.e. suction, compression, power and exhaust stoke. Only in the power stroke we get power and in the rest of the strokes, the power is required to perform different process like suction, compression and exhaust process. So we need a device which can stores the power during power stroke and deliver that power to the remaining strokes when required. This could be done with the use of a flywheel. The flywheel stores the power during the expansion or power stroke and then imparts this power to the remaining strokes of the engine for its working. How flywheel is attached to the crankshaft? The Flywheel is made of heavy steel or cast iron and it is attached to the rear end of the crankshaft. The weight of the flywheel depends upon the nature of the variation of the pressure, number of cylinder and design of engine. The weight of the flywheel decreases with the increase in the number of cylinder. It means a two cylinder engine has lighter flywheel as compared with single cylinder engine. Working of Flywheel- Out of four strokes, we get power only in single stroke (i.e. power stroke) and in the remaining 3 strokes power is required for the intake of fresh charge, compression of fresh charge and for the exhaust of burnt gases. During power stroke, the engine tends to speed up and tends to slow down during the remaining 3 strokes. But flywheel, due to its moment of inertia resists the speed up of engine during power stroke and resist the slow down of engine during preparatory strokes. It stores the energy (rotational energy) when the engine tries to speed up and imparts that energy to the engine when it tends to slow down. In this way the flywheel keeps the engine running at constant speed which is essential for the smooth working of the automobile. Main Function of the Flywheel- 1. It provides constant power output where there is a fluctuation in the power is observed. 2. It maintains the constant speed of the engine during all the strokes. 3. It stores the mechanical energy (rotational energy) of the engine and deliver it when required. Application- 1. Flywheel is mainly used in engines and fabricating machines (rolling mills, punching machines, presses etc) to get uniform speed during its working. 2. It is also used as a part of clutch mechanism and fluid drive unit. The clutch assembly is mounted on the flywheel and rotates with it. The wait is finally over.

What is Coupling? | Types of Coupling in Hindi with Animation
 
13:51
In mechanical system coupling can be defined as a kind of linkage between two rotating shafts which joins driving and driven shafts together. The joint between two shafts may be permanent or temporary. In simple words we can say that coupling is used to join input and output shafts in any power transmission system such as in machine tools gear box shaft is connected to the input engine shaft by means of coupling; engine shaft with pump or compressor shafts etc. The function of the coupling is almost same as the clutches but clutches are temporary joint while the coupling joints are permanent connection. According to the requirement and functions different types of coupling are used. The basic features of the different types of coupling are almost same which are given as follow: 1. Power Transmission 2. Join misaligned shafts 3. Reduce shocks and vibration 4. Easily to assemble and disengage Types of Couplings: 1. Oldham’s Coupling: Oldham’s coupling is used to connect the two parallel shafts when some eccentricity is present between two rotating shafts. In this the two misaligned shafts have disc shape flanges with rectangular slot at the middle. Both the flanges have slot cut which is at right angle to each other. In between two shaft a circular disc assembled having tongue on both side at right angle to fit between the slots of flanges. When shafts rotate then the tongue of the flanges slides into the recess of the flanges of the shafts. The middle disc rotates about its center but both the misaligned shafts rotate their own axis by means of sliding tongue into the grooves which results the center of the middle disc traces a circular orbit. A spring is required to remove the backlash of this running coupling. 2. Hook’s Coupling: This is also known as hook’s joint, universal joint or coupling. It is called universal joint because it can able to joint two shafts having intersecting axes. It is used to joint connect two non-parallel and intersecting shafts which has some angular misalignment. The input and output shafts are connected using hook’s joint. The input driving shaft rotates at a uniform angular speed while the driven shaft rotates with varying angular speed i.e. both shafts have different angular speed. Both the shafts rotate in fixed bearing and have a fork at the end. Each fork has four ends and sides which are connected by center piece. 3. Double Hook’s coupling: As name implies a double hook joint has two hook’s joint or universal joint which are connected by means of an intermediate shaft. 4. Rigid Coupling: Rigid coupling is used where the axes of both the shafts are collinear. Rigid couplings are simple and less costly, but the major drawback of this type of coupling is that they cannot tolerate any kind of small misalignment between the axis of the shafts. Different types of coupling come under this category some are them are as follow: a.) Muff coupling: This coupling also known as sleeve coupling because it has sleeve or a kind of hollow cylinder. The driven and driving shafts are joined in the sleeve by means of a key. Generally sunk key is used in muff coupling which makes it simplest coupling among all. The force transformation takes place from driving shaft to key then from key to sleeve and then to the driven shaft by means of key. Shearing force between the key and shaft is responsible for the power transmission. b.) Clamp coupling: Clamp coupling is the modified form of the muff coupling and also known as split muff coupling i.e. it has sleeve which is divided into the two half that’s why it is known as split muff coupling. The two-split portion of the sleeve are clamped together using nuts and bolts. Both the shafts tightened together into the clamps, 4 or 8 nuts are used to tight the shaft into the split muffs. c.) Flange coupling: As name implies flange coupling has flanges for the joining of both the shafts. It is another type of rigid coupling so all the conditions are also applicable here like proper alignment of both the shafts and connection should not have any kind of vibrations and jerks. 5. Flexible coupling: This is another category of coupling. As name suggest it has flexible connection between the input and the output shaft because it is very difficult to make a proper aligned connection between the two mating shafts and there are various reasons for the misalignment between the two shafts such as deflection of shafts, thermal expansions etc. so to remove all such causes flexible coupling comes into the play.

Working of a Two Stroke Engine in Hindi with Animation
 
04:26
In small engines, the exhaust and inlet ports are made in the cylinder block. When a piston comes down from the Top Dead Center (TDC) to the Bottom Dead Center (BDC) during a power stroke, it opens the exhaust port. Due to this uncovering of the port, exhaust gases are allowed to escape. As the piston travels down a little more, it also uncovers the inlet port which is usually located opposite the exhaust port. Due to uncovering of the inlet port by the piston, a fresh charge comes into the cylinder. Hence, suction and exhaust are completed in one stroke. When a piston travels up from the BDC to TDC, it covers both, the inlet and exhaust ports and so the charge gets trapped and compressed. This is the commencement of a compression stroke. When a piston reaches the TDC, a spark is triggered from the spark plug and the charge (the mixture of air and fuel) ignites. The charge gets expanded due to rapid combustion caused by the explosion and it causes the piston to move down with force. This is known as a power stroke. At the same time, when the piston is at the TDC, the piston skirt uncovers the port in the cylinder block from where a fresh charge goes into the crank case due to a partial vacuum created by the crank shaft and its weight. Thereafter, when the piston starts moving down in a power stroke, the charge which has come in to the crank case is pressed by crank weights to the inlet port side, ready to be taken to the cylinder. In this way, a whole cycle is completed. Working of a Four Stroke Engine in Hindi with Animation: https://youtu.be/bQ5u7bLs1F0 The wait is finally over.

Components of Automobile Engine in Hindi

The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly. Valves The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Note that both valves are closed during compression and combustion so that the combustion chamber is sealed. Piston A piston is a cylindrical piece of metal that moves up and down inside the cylinder. Piston rings Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. The rings serve two purposes: They prevent the fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion. They keep oil in the sump from leaking into the combustion area, where it would be burned and lost. Most cars that "burn oil" and have to have a quart added every 1,000 miles are burning it because the engine is old and the rings no longer seal things properly. Connecting rod The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates. Crankshaft The crankshaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does. Sump The sump surrounds the crankshaft. It contains some amount of oil, which collects in the bottom of the sump (the oil pan).

How Alternator Works in Hindi With Animation
 
04:21
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. An automotive charging system is made up of three major components: the battery, the voltage regulator and an alternator. The alternator works with the battery to generate power for the electrical components of a vehicle, like the interior and exterior lights, and the instrument panel. An alternator gets its name from the term alternating current (AC). 'The 3D Models, Animations and Images are courtesy of https://savree.com/'. Alternators are typically found near the front of the engine and are driven by the crankshaft, which converts the pistons' up-and-down movement into circular movement. Some early model vehicles used a separate drive belt from the crankshaft pulley to the alternator pulley, but most cars today have a serpentine belt, or one belt that drives all components that rely on crankshaft power. Most alternators are mounted using brackets that bolt to a specific point on the engine. One of the brackets is usually a fixed point, while the other is adjustable to tighten the drive belt. The alternator is comprised of a voltage regulator and three main components: The stator, rotor, and diode. When the battery initially powers the car, the alternator belt, or V-belt, spins the pulley on the alternator, causing the rotor inside the alternator to spin very quickly. This rotor, which is basically a magnet or group of magnets, is situated inside a nest of copper wires, which are called the stator. The process whereby electricity is generated by spinning magnets at incredibly fast speeds along a set of copper wires is called electromagnetism. The electricity harnessed this way is conducted through the copper wires to a diode, which changes the electricity from AC to DC, the current that the car battery uses. The next step happens within the voltage regulator—a built-in component on modern alternators—which is basically a gatekeeper that will shut off the flow of power to the battery if the voltage goes above a certain level, usually 14 and a half volts, which keeps the battery from getting overcharged and burning out. As the car battery is drained, current is allowed to flow back into it from the alternator, and the cycle goes on and on.

Types of Springs in Hindi
 
03:37
The springs are defined as an elastic body which stores mechanical energy and gets distorted when loaded and regains its original shape when load is removed. Springs main function is to get distorted when it is loaded and recover its original shape when load is removed. The various applications of springs are as follows: 1. To cushion, absorb or control energy due to shock and vibration as in bike or car springs, railway buffers, shock absorbers, aircraft landing gears and vibration dampers. 2. To apply forces, as in brakes, clutches and spring loaded valves. 3. To controls the motion by maintaining contact between two elements as in cams and followers. 4. To measure forces, as in spring balances and engine indicators. 5. To store energy, as in toys and watches. Types of springs: 1. Helical Springs or Coil Springs It is a spring which is made up of a wire coiled in the form of helix. It is made to handle tensile and compressive loads. 2. Conical and Volute Springs These are the compression spring have conical shapes. The conical springs are wounded with a uniform pitch whereas the volute springs are wounded in the form paraboloid with constant pitch and lead angles. Under compression, coils of these springs slide past each other and make the spring to compress to a very shorter length. 3. Torsion Springs It is a spring that works on torsion or twisting. It stores the mechanical energy when twisted. 4. Laminated or Leaf Springs It is a type of spring which is mostly used in automobile suspension, electrical switches and bows. It consists of a number of flat plates (known as leaves) of varying lengths held together by means of clamps and bolts. 5. Disc or Belleville Springs It is a disc shaped spring. It is commonly used to apply tension to a bolt. It is also called as Belleville washers and conical compression washers. On the basis of how the load force is applied springs are classified as: 1. Tension or Extension Spring Tension or extension springs works on the application of tension loads. When tensile load is applied to this spring it extends to some length. 2. Compression Spring The compression springs are designed to operate when compressive load is applied to it. It contracts under compression. 3. Torsion Spring It is designed to work under twisting. It stores mechanical energy when twisted. 4. Constant Spring It is a type of spring in which the supported load remains the same throughout the deflection cycle. 5. Variable Spring Variable spring is a spring in which the resistance in the coil to load varies during compression. The wait is finally over.

OCTANE NUMBER and CETANE NUMBER |
 
02:56
An octane rating, or octane number, is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). In broad terms, fuels with a higher octane rating are used in high performance gasoline engines that require higher compression ratios. In contrast, fuels with lower octane numbers (but higher cetane numbers) are ideal for diesel engines, because diesel engines (also referred to as compression-ignition engines) do not compress the fuel, but rather compress only air and then inject fuel into the air which was heated by compression. Gasoline engines rely on ignition of air and fuel compressed together as a mixture, which is ignited at the end of the compression stroke using spark plugs. Therefore, high compressibility of the fuel matters mainly for gasoline engines. Use of gasoline with lower octane numbers may lead to the problem of engine knocking. Cetane number (cetane rating) is an indicator of the combustion speed of diesel fuel and compression needed for ignition. It is an inverse of the similar octane rating for gasoline. The CN is an important factor in determining the quality of diesel fuel, but not the only one; other measurements of diesel's quality include (but are not limited to) energy content, density, lubricity, cold-flow properties and sulphur content.

What is Clutch? | Types, Components and Requirements in Hindi
 
05:20
Clutch is a device which is used to transmit power from one shaft to another. It connects a shaft on which it is mounted to another shaft which is in motion. Clutches are generally used in automobile to transmit power from engine to the driving wheels. In cars it transmits power from the flywheel connected to the engine shaft to the clutch shaft, and from clutch shaft it is transmitted to the rear wheels through gear shaft, propeller shaft and differential. Requirements of a Good Clutch- Gradual Engagement: The clutches should be engaged gradually so that the sudden jerks produced must be avoided. Size: The size of the clutch should be so small, so that it can be fit into minimum space. Torque Transmission: The clutch should be so designed, so that it can able to transfer maximum power through it. Heat Dissipation: It should be so designed, so that maximum dissipation of heat takes place from it. Dynamic Balancing: For high speed clutches dynamic balancing is necessary. Provision of Clutch Free Pedal: There should be a clutch free pedal in engaging or disengaging of clutch. Ease of Operation: Engaging and disengaging of the clutch should not be difficult or tiresome to the operator. Vibration Damping: The clutch should be so designed, so that the noise or vibration produced in the transmission can be eliminated easily. Types of clutches: 1. Cone clutch 2. Single plate clutch 3. Multi-plate cutch 4. Semi-centrifugal clutch 5. Centrifugal clutch The main parts of a clutch are mainly divided into three groups- 1. Driving Members: The driving members consists of a flywheel which is mounted on the engine crankshaft The flywheel is bolted to a cover which carries pressure plate, pressure springs and releasing levers. As the flywheel is bolted to the cover assembly, thus, the entire assembly of the flywheel and the cover rotate all the times. The clutch housing and cover provided with openings so that the heat produced during the function dissipates easily. 2. Driven Members: The driven members consists of a disc or plate called clutch plate. The clutch is free to slide on the splines of the clutch shaft. It carries friction materials on both of its surfaces. When the clutch plate is gripped between the flywheel and the pressure plate, it rotates the clutch shaft through splines. 3. Operating Members: The operating members consists of a foot pedal, linkage, release or throw out bearings. The wait is finally over.

Working of a Diesel Engine in Hindi with Animation
 
05:16
A diesel engine works differently from a petrol engine, even though they share major components and both work on the four-stroke cycle. The main differences are in the way the fuel is ignited and the way the power output is regulated. In a petrol engine, the fuel/air mixture is ignited by a spark. In a diesel engine, ignition is achieved by compression of air alone. A typical compression ratio for a diesel engine is 20:1, compared with 9:1 for a petrol engine. Compressions as great as this heat up the air to a temperature high enough to ignite the fuel spontaneously, with no need of a spark and therefore of an ignition system. A petrol engine draws in variable amounts of air per suction stroke, the exact amount depending on the throttle opening. A diesel engine, on the other hand, always draws in the same amount of air (at each engine speed), through an unthrottled inlet tract that is opened and closed only by the inlet valve (there is neither a carburettor nor a butterfly valve). When the piston reaches the effective end of its induction stroke, the inlet valve closes. The piston, carried round by the power from the other pistons and the momentum of the flywheel, travels to the top of the cylinder, compressing the air into about a twentieth of its original volume. As the piston reaches the top of its travel, a precisely metered quantity of diesel fuel is injected into the combustion chamber. The heat from compression fires the fuel/air mixture immediately, causing it to burn and expand. This forces the piston downwards, turning the crankshaft. As the piston moves up the cylinder on the exhaust stroke, the exhaust valve opens and allows the burned and expanded gases to travel down the exhaust pipe. At the end of the exhaust stroke the cylinder is ready for a fresh charge of air.

Babcock and Wilcox Boiler | Construction and Working
 
05:08
Babcock and Wilcox is a stationary water tube boiler. It has inclined tubes which are inclined at 10 to 15 degree, which are inclined to maintain natural circulation of water from drum to tubes and steam from tubes to drum. The main parts of this boiler are as follow: 1. Steam separator drum: This drum is situated upside of the boiler. It is larger diameter drum in which water and steam placed together. The one half of the drum is filled with water and the other half is remaining for steam. 2. Water tubes: Water tubes are situated bottom side of the drum. Water flows from the drum to the tubes. 3. Uptake header: Steam separator drum and water tubes are connected by the two tubes. One is known as uptake header and the other one is known as down take header. The steam from the water tubes to the drum flow by the uptake header. 4. Down take header: The water flows form the drum to the water tubes through down take header. When the steam flows by uptake header to the drum, at the same time water flows from drum to the water tubes by down take header which maintains the flow of water. 5. Grate: The place in the furnace, where the fuel is placed and burn known as grate. 6. Furnace: The furnace is the place where the fuel burns. This is situated at the down side of the water tubes. When the fuel burns, the flue gases generate. This gases flow upper side and passes through water tube, which heat the water and convert it into steam. 7. Super heater: Super heater is situated upper side of the water tube. One end of super heater is connected to the drum and other end is for process work. Steam flows from the drum to the super heater, where it heated by the flue gases and send for the process work. 8. Baffles: Baffles are provided between the water tubes. The main function of baffles is to divert the flue gases, so it flows more than one time through the tube and more heat is transfer. Other mounting like safety valve, blow off valve, fuel door, inspection door, mud box, feed valve, stop valve, pressure gauge etc. are also provided for safely working of boiler. Working: Now we discuss about working of Babcock and Wilcox boiler. This is a high pressure, natural circulate, water tube boiler. The working of this boiler is as follow. * First water is filled in the water drum through feed pump. The drum is half filled with water and the upper half is for steam. First flue is fired at the grate. * The flue gases generate by burning of fuel. These gases start flowing from one end to another end of boiler. * The flue gases passes by the water tubes and exchange heat with water. The baffles are provided in the way, which deflects the flue gases before escaping from the chimney. Due to this deflection, the flue gases pass more than one time through water tubes, which cause more heat transfer. * The water flows from the drum to the water tube through down take header. * The water tube nearer to the furnace heated more than the other, so the density of water decrease in this tube which causes the flow of steam from tube to drum through uptake header. At the same time the water from the drum enters into the tubes through down take header. * The circulation of water from drum to tubes and again tubes to drum is natural, due to density difference. * The steam separates in the drum at the upper half. This is saturated steam. This steam sends to the super heater through steam pipe. The steam is heated again by the flue gases in the super heater and taken out for process work. * The flue gases send to the atmosphere from the super heater. * This process repeat until sufficient amount of steam generates. This boiler can generate 20 ton steam per hour.

How Suspension System Works in Automobile in Hindi
 
11:42
A suspension system provides stability to the vehicle in dynamic conditions like high speed, sharp turns and braking. The shock absorbers used in suspension system prevents the main frame from the shocks provided by the rough road conditions by absorbing the shocks which in turn makes the ride smooth for the passengers and the luggage. Types of Suspensions Used: 1. Non-independent or dependent suspensions – A suspension system in which both the right and the left wheels of the front and the rear pair of wheels are connected with a solid axle in such a way that the upward motion due to the bump in any one wheel of the front and the rear wheels pair causes slight lift in the other. De-dion tube solid axel etc. Types of Suspensions are the examples of dependent suspension This type of suspensions are used in many old trucks in which the front and rear pairs of wheels are connected with a solid axle. 2. Independent suspension- A suspension system in which all the four wheels of the vehicle are free i.e. there is no relative motion between the front and the rear pairs of the wheels which means all the four wheels are connected independently with the frame and when a bump comes either in right or left side of the vehicle the wheel (either right side wheel or left side wheel)in contact with the bump moves upward without causing any lift in the other side wheel. Double wishbone , mac-pherson, etc. Types of suspensions are the example of independent suspension. Main Components of the Suspension System: 1. Knuckle or Upright- It is the component of the suspension system that is mounted over the wheel’s hub through which the wheels and the suspension of the vehicle connect with each other by the linkages provided. 2) Spring: The springs are critical components in the suspension system that absorbs the shocks and bumps while the car is in motion. Most cars have four springs that are generally designed to last the lifetime of the car. Generally made from steel, the spring is the core component of all suspension systems. 3) Shocks: Shocks or shock absorbers are another important component that are generally fluid filled and work in tandem with the spring to minimize the shocks or vibrations that are caused by the vehicle in motion. 4) Strut: Struts are components that join the spring and the and the shocks. In their most basic form struts provide dampening function as well as structural support for the vehicle suspension. Struts and shocks are absolutely critical components in the suspension of a vehicle. 5) Anti Sway Bars: Another critical component, the anti sway or anti roll bars are used for providing further stability to the moving vehicle. The anti sway bar is basically a metal bar that joins the different sides of the suspension and helps in reducing the vehicle sway. 6) Ball Joints: The vehicle suspension is designed to move up and down while the vehicle is in motion which is connected to the spindle by ball joints. These Ball Joints are basically ball and socket joints that allow multi dimensional movement. Ball joints are lubricated with grease and sealed. 7) Spindle: The Spindle is an important part of the vehicle suspension system that ties the wheel and tyre into the steering system. The spindle is situated in the front of most vehicles and is like a short axle that is used to attach the wheel assembly to the vehicle. Working of Suspension Systems: Independent Suspension- Let assume that the bump is in left side of the vehicle and at the instant the front left tyre comes in contact with it. When the left tyre of the formula car hits the road bump which in turn causes front left tyre to lift upward and as there is no connection between the right and the left or front and the rear tyres this upward movement is only restricted to the front left wheel. The shock produced due to this road bump is absorbed by the compression type spring and dampers used in between the wheel’s knuckle and the main frame, this shock is absorbed directly or through push roads that transfer the shock from knuckle to the damper. The stiffness of the spring and dampers used in independent double wishbone suspension is responsible for maintaining the traction of the formula car’s wheel with the road. Non- Independent or Dependent Suspension- Let’s assume the bump is at the left tyre of the truck, this road bump faced by the left tyre of the truck tries to lift the left wheel of the truck. When this wheel lifts up due to the road bump the solid axle attached with it also lifts up and the force generated by the wheel due to its upward movement is transferred to corresponding right wheel (as they are both rigidly connected with the live axle) which in turn tries to lift it up slightly. The shock produced by the road bump is absorbed by the leaf springs used in between the axle and the main frame. Contact me: ⤵ [email protected]

Normal Petrol Vs Extra Premium Petrol | Car/Bike ke liye Kya Sahi Hai?
 
06:33
Octane number of extra premium is 91-93 and that of normal petrol is 85-87. Higher the octane number, higher is the efficiency of engine. But there is not much difference between the octane number of two, so mileage will increase by only 3-4 kmpl. In short, extra premium petrol should be used after the vehicle has run few thousand kilometers as it contain some cleaning additives. What is octane no. and cetane no. - https://www.youtube.com/watch?v=UNeG6bCvKXM So if you got a vehicle with engine compression ratio 10 or more… it will work fine with normal petrol. But with extra premium, very high compression ratio vehicles will clock their best BHP. Petroleum is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column. It consists of hydrocarbons of various molecular weights and other organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling (natural petroleum springs are rare). Drilling is carried out after studies of structural geology (at the reservoir scale), sedimentary basin analysis, and reservoir characterisation (mainly in terms of the porosity and permeability of geologic reservoir structures) have been completed. It is refined and separated, most easily by distillation, into a large number of consumer products, from gasoline (petrol) and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. Petroleum is used in manufacturing a wide variety of materials, and it is estimated that the world consumes about 95 million barrels each day. Concern over the depletion of the earth's finite reserves of oil, and the effect this would have on a society dependent on it, is a concept known as peak oil. The use of fossil fuels, such as petroleum, has a negative impact on Earth's biosphere, damaging ecosystems through events such as oil spills and releasing a range of pollutants into the air including ground-level ozone and sulfur dioxide from sulfur impurities in fossil fuels. The burning of fossil fuels plays a major role in the current episode of global warming. The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

What is Compression Ratio? | Petrol and Diesel Engine in Hindi with Animation
 
07:58
A compression ratio (CR) of an I C engine is the ratio of the total volume of the combustion chamber To the volume left after complete compression i.e. clearance volume. In simple words it is the ratio between the total volume of the combustion chamber which is left when the piston is at its bottom dead center and the volume left inside the combustion chamber when the piston moves to its top dead center. What is the Need of Compression Ratio? 1. Petrol Engine- As we all know the in petrol engine air-fuel mixture enters the combustion chamber during the suction stroke and for proper mixing and for proper combustion of this air-fuel mixture compression of this mixture is required which is done by the engine in its compression stroke, so a good compression ratio of the petrol engine is required for proper combustion of the air-fuel mixture which in turn provides better thermal efficiency. The pressure inside the cylinder increases during compression stroke which in turn raises the temperature of the air-fuel mixture that leads to a complete or proper combustion of the fuel when the spark plug produces spark which in turn provide better fuel economy and also prevents the engine from various defects like knocking. The petrol engine with proper CR provides a balanced amount of power and speed. The petrol engine usually comes with 10:1 to 14:1 compression ratio depending upon the application and design requirement. 2. Diesel Engine- In diesel engine a high CR is required as the diesel engine doesn’t have any spark plug so the combustion of the fuel completely depends upon the compression of the air provided by the compression stroke of the diesel cycle because of which diesel engine is also known as compression ignition engine. The diesel engine with high compression ratio provides the engine with high compression i.e. provides high pressure rise, which is required to increase the temperature of the compressing air to the extent of the auto ignition temperature of the fuel that is to be sprayed by the fuel injectors which in turn provide complete or proper combustion of fuel. The diesel engines are known for providing high power output which is due to the high compression ratio of the diesel engine, as we know higher the CR higher will be the thermal efficiency or work output. A diesel engine with high CR provides high fuel economy due to the higher thermal efficiency provided by the high compression combustion. Diesel engines usually come with higher compression ratios varies from 18:1 to 23:1 depending upon the application and the design requirement. Design Criteria on which the compression ratios depends- 1. Stroke length – The stroke length of an engine is the length of the combustion chamber or the distance between the TDC and BDC of an engine cylinder, the compression ratio depends on the stroke length, as higher the stroke length of the engine cylinder higher will be its CR. 2. Bore diameter – The shape of an engine cylinder is cylindrical so the bore diameter of an engine is the diameter or inner diameter of the engine’s cylinder inside which the piston is moving, The compression ratio of an engine depends upon the bore diameter as higher the bore diameter of an engine higher will be the compression ratio. 3. Square engine – These are the type of engines in which the stroke length of the cylinder is made equal to the bore diameter of the engine’s cylinder which gives a proper balanced power and speed output. 4. Number of cylinders – Number of cylinders also affects the CR of an engine as the engine with higher number of pistons provides higher compression ratios. The wait is finally over.

Types of Braking System in Automobile in Hindi
 
16:43
In an automobile vehicle, a braking system is an arrangement of various linkages and components (brake lines or mechanical linkages, brake drum or brake disc , master cylinder or fulcrums etc) that are arranged in such a fashion that it converts the vehicle’s kinetic energy into the heat energy which in turn stops or de-accelerate the vehicle. Different Types of Braking Systems: On Power Source Basis- 1. Mechanical Brakes- It is the type of braking system in which the brake force applied by the driver on the brake pedal is transferred to the final brake drum or disc rotor through the various mechanical linkages like cylindrical rods, fulcrums, springs etc. In order to de accelerate or stop the vehicle. 2. Hydraulic Brakes- It is the type of braking system in which the brake force applied by the driver on brake pedal is first converted into hydraulic pressure by master cylinder than this hydraulic pressure from master cylinder is transferred to the final brake drum or disc rotor through brake lines. 3. Air or Pneumatic Brakes- It is the types of braking system in which atmospheric air through compressors and valves is used to transmit brake pedal force from brake pedal to the final drum or disc rotor. 4. Vacuum Brakes- It is the conventional type of braking system in which vacuum inside the brake lines causes brake pads to move which in turn finally stops or de accelerate the vehicle. Exhauster , main cylinder , brake lines , valves along with disc rotor or drum are the main components that combines together to make a vacuum braking system 5. Magnetic Brakes– In this types of braking system, the magnetic field generated by permanent magnets is used to cause the braking of the vehicle. It works on the principle that when we pass a magnet through a cooper tube, eddy current is generated and the magnetic field generated by this eddy current provide magnetic braking. 6. Electrical Brakes- It is type of braking used in electric vehicle in which braking is produced using the electrical motors which is the main source of power in electric vehicles, it is further divided into 3 types- (i) Plugging Brakes-When the brake pedal is pressed in the electric vehicle equipped with plugging braking, the polarity of the motors changes which in turn reverses the direction of the motor and causes the braking. (ii) Regenerative Braking- It is the type of electrical braking in which at the time of braking the motor which is the main power source of the vehicle becomes the generator i.e. when brakes are applied, the power supply to the motor cuts off due to which the mechanical energy from the wheels becomes the rotating force for the motor which in turn converts this mechanical energy into the electric energy which is further stored in the battery. (iii) Dynamic or Rheostat Braking- It is the type of electrical braking in which resistance provided by the rheostat causes the actual braking On Frictional Contact Basis 1. Drum Brakes or Internal Expanding Brakes It is the type of brake system in which a drum which is the housing of the brake shoes along with actuation mechanism is attached with the wheel hub in such a fashion that the outer part of the drum rotates with the wheel and inner part remains constant. When brakes are applied the actuating mechanism (wheel cylinder or mechanical linkage.) causes the brake shoes to expand due to which the outer frictional surface of the brake shoes makes frictional contact with the rotating drum part which in turn stops or de accelerate the vehicle. 2. Disc Brake or External Contracting Brakes – It is the types of braking system in which instead of a drum assembly a disc rotor attached to the hub of the wheel in such a fashion that it rotates with the wheel, this disc rotor is clamped in between the caliper which is rigidly fixed with the knuckle or upright of the vehicle. On Application Basis- 1. Service Brake or Foot Brakes. 2. Hand Brake or Parking Brake. On Brake Force Distribution Basis- 1. Single Acting Brakes- It is the type of braking in which brake force is transferred to either a pair of wheels(in cars) or to the single wheel(in bikes) through single actuation mechanism(mechanical linkages or master cylinder). 2. Dual Acting Brakes- It is the type of braking in which the brake force is transferred to all the wheels of the vehicle through dual actuation mechanism (tandem master cylinder or mechanical linkages).

Types of Gears in Hindi
 
06:38
A gear drive has three main functions: to increase torque from the driving equipment (motor) to the driven equipment, to reduce the speed generated by the motor, and/or to change the direction of the rotating shafts. The connection of this equipment to the gear box can be accomplished by the use of couplings, belts, chains, or through hollow shaft connections. Speed and torque are inversely and proportionately related when power is held constant. Therefore, as speed decreases, torque increases at the same ratio. The heart of a gear drive is obviously the gears within it. Gears operate in pairs, engaging one another to transmit power. 'The 3D Models, Animations and Images are courtesy of https://savree.com/'. Sprocket Gear- Sprockets are used to run chains or belts. They are typically used in conveyor systems. Face Gears- Face gears transmit power at (usually) right angles in a circular motion. Face gears are not very common in industrial application. Rack and Pinion- A rack is a toothed bar or rod that can be thought of as a sector gear with an infinitely large radius of curvature. Torque can be converted to linear force by meshing a rack with a pinion: the pinion turns; the rack moves in a straight line. Such a mechanism is used in automobiles to convert the rotation of the steering wheel into the left-to-right motion of the tie rod(s). Racks also feature in the theory of gear geometry, where, for instance, the tooth shape of an interchangeable set of gears may be specified for the rack (infinite radius), and the tooth shapes for gears of particular actual radii then derived from that. The rack and pinion gear type is employed in a rack railway. Worm Gear- Worm gears are used to transmit power at 90° and where high reductions are required. The axes of worm gears shafts cross in space. The shafts of worm gears lie in parallel planes and may be change at any angle between zero and a right angle.In worm gears, one gear has threads. Due to this, worm gears are quiet, vibration free and give a smooth output.Worm gears and worm gear shafts are almost invariably at right angles. Bevel Gear- Bevel gears are most commonly used to transmit power between shafts that intersect at a 90 degree angle. They are used in applications where a right angle gear drive is required. Bevel gears are generally more costly and are not able to transmit as much torque, per size, as a parallel shaft arrangement. Spiral Bevel gears: In these Spiral Bevel gears, the teeth are oblique. Spiral Bevel gears are quieter and can take up more load as compared to straight bevel gears. Herringbone Gear- Herringbone gears are very similar to the double helical gear, but they do not have a gap separating the two helical faces. Herringbone gears are typically smaller than the comparable double helical, and are ideally suited for high shock and vibration applications. Herringbone gearing is not used very often due to their manufacturing difficulties and high cost. Helical Gear- Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel. This causes more than one tooth to be in contact during operation and helical gears are capable of carrying more load than spur gears. Due to the load sharing between teeth, this arrangement also allows helical gears to operate smoother and quieter than spur gears. Helical gears produce a thrust load during operation which needs to be considered when they are used. Most enclosed gear drives use helical gears. Spur Gear- Spur gears transmit power through shafts that are parallel. The teeth of the spur gears are parallel to the shaft axis. This causes the gears to produce radial reaction loads on the shaft, but not axial loads. Spur gears tend to be noisier than helical gears because they operate with a single line of contact between teeth. While the teeth are rolling through mesh, they roll off of contact with one tooth and accelerate to contact with the next tooth. This is different than helical gears, which have more than one tooth in contact and transmit torque more smoothly. The wait is finally over.

Components of Automobile Engine - Part 2
 
06:50
The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly. Valves The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Note that both valves are closed during compression and combustion so that the combustion chamber is sealed. Piston A piston is a cylindrical piece of metal that moves up and down inside the cylinder. Piston rings Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. The rings serve two purposes: They prevent the fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion. They keep oil in the sump from leaking into the combustion area, where it would be burned and lost. Most cars that "burn oil" and have to have a quart added every 1,000 miles are burning it because the engine is old and the rings no longer seal things properly. Connecting rod The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates. Crankshaft The crankshaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does. Sump The sump surrounds the crankshaft. It contains some amount of oil, which collects in the bottom of the sump (the oil pan).

ENGINE THERMOSTAT | Working and Components | Hindi with Animation
 
07:14
Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. When the engine is cold, no coolant flows through the engine. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions. Iss video me maine detail me thermostat ke components ke bare me bataya hai, iske alawa maine thermostat 3D model ke help se iske working ke bare me bhi bataya hai.

Types of Gearbox in Automobile | Complete Explanation in Hindi with Animation
 
11:43
A gearbox is a transmission device which is used between engine’s output shaft and the final drive in order to transfer required torque and power to the wheels of the vehicle, a gearbox consists of the set of gears( i.e. spur, helical, bevel, worm and epicycle depending on the types of gearbox used )which are arranged in a special fashion in order to provide required gear or speed ratios to the final drive of the vehicle, a gearbox usually comes with the specification i.e.5-speed transmission with a reverse, and an automatic transmission. Why do we need Gearbox? When a car starts ,the torque provided by the engine output shaft is not enough to overcome the weight of the vehicle which make it difficult to move the car initially, so to solve this problem a gearbox is required which can provide high torque initially in order to move the vehicle. When we go to the hill station it is essential that the vehicle should be equipped with device that can provide a wide range of high torque, to fulfill this need a gearbox is required so that a vehicle can go to the hills. When a vehicle is going at high speed, torque is not at all effective so a gearbox is needed that can also provide a high speed low torque ratio so that vehicle can maintain the high speed. In a race car continuous change of gears from high torque to high speed is there due to the curvy track so the race car should be equipped with a suitable gearbox so that shifting of gears is smooth and easy. Main Parts of a Gearbox- 1. Main Shaft It is the shaft used as an output shaft in a gearbox, this shaft is usually kept parallel to the lay shaft and in front of the clutch shaft or engine output shaft, the change of gear usually occur through this shaft as it is usually connected to gear lever. 2. Clutch Shaft It is the shaft which carries the engine output to the gearbox, the engaging and disengaging of the engine output occurs with the help of clutch. 3. Lay Shaft or Counter Shaft It is the shaft through which the output of the engine is transferred to the main shaft by the continuous meshing of a gear on the lay shaft to the gear on the clutch shaft. 4. Gears They are the connecting circles with teeth that rotates and meshes with another gear on the different shaft in order to transmit the circular motion between 2 different shafts, they can be –spur gear, helical gear, bevel gear and worm gear. 5. Synchromesh Devices They are the special devices used in modern gearbox (synchromesh gearbox) that makes the shifting of gears smooth by bringing the speed of main-shaft, lay-shaft and clutch-shaft at the same, they doesn’t have to slide over the shaft for the shifting of the gear. 6. Dog Clutches They were used in old gear boxes like constant mesh gearbox, to avoid the sliding of gear over the shaft for meshing or shifting. As they slide over the shaft in order to shift a gear. 7. Gear lever It is the lever operated by the driver to change or shift the gear, the movement of the lever is designed in a particular fashion. Types of Gearbox- 1. Manual Transmission A manual transmission is the types of gearbox used in most of the vehicle on the road due to its low cost. It is the type of gearbox in which there are limited gear or speed ratios i.e. maximum of 6- speed and 1- reverse is there, and the shifting of gears is a manual task performs by the driver by pushing or pulling the gear lever in predefined fashion. Manual transmission always requires the use of clutch. Types of manual transmission used since the introduction of the gearbox are: (i) Sliding Mesh Gearbox (ii) Constant Mesh Gearbox (iii) Synchromesh Gearbox 2. Automatic Transmission or Gearbox It is used in high-end cars due to its high cost, in this types of gearbox infinite gear ratios can be obtained by just pressing the accelerator, the driver just need to select the mode of the drive i.e. forward or reverse, park, neutral, drive and sport, and the required gear ratios along with the timing of the meshing is obtained automatically. Automatic gearbox doesn’t require clutch pedal, so all the cars with automatic transmissions comes with only 2 pedals. Types of automatic transmission used are- (i) Epicyclic Gearbox (ii) Hydraulic Torque Converter The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

What does the Numbers on tyres means ? | टायर पर लिखी संख्याओं का अर्थ क्या है ?
 
04:54
Automobile tyres are described by an alphanumeric tyre code, which is generally molded into the sidewall of the tyre. This code specifies the dimensions of the tyre, and some of its key limitations, such as load-bearing ability, and maximum speed. Sometimes the inner sidewall of the tyre - for tyres with demarcated inner and outer walls - contains information not included on the outer sidewall, and vice versa. Tyre coding has grown in complexity over the years and now is a mix of units, lettering and numbering schemes. The first part of the number is the width of the tyre in millimetres. The letter R denotes Radial construction. Watch the full video to understand. The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

Car Sensors Used in Automobile Engine and Their Functions in Hindi
 
12:11
Today’s modern automobiles have a variety of sensors. These sensors built into their engine to ensure that the owner can identify and prevent possible issues before they result in breakdowns can result in expensive repairs. These automobile engine sensors also ensure that the vehicle is operating at its most efficient. The Mass Air Flow Sensor (MAF) From different types of sensors used in cars, The Mass Air Flow Sensor (MAF) is a computer-controlled sensor that calculates the volume and density of the air taken in by the engine. This in turn ensures the right amount of fuel is used for optimized operating conditions. If this sensor is faulty, the car may stall and the fuel usage will be higher than necessary. The Engine Speed Sensor Engine Speed Sensor is attached to the crankshaft and monitors the spinning speed of the crankshaft, which controls the fuel injection and timing of the engine. There are many ways for car engine to stop suddenly, and this sensor will prevent that for drivers. Oxygen Sensor The Oxygen sensor measures the amount of unburden oxygen that is present in the exhaust pipe and will indicate if the fuel is burning rich or lean. A faulty oxygen sensor will cause the car to idle poorly and jerk as well as cause high fuel consumption. Manifold Absolute Pressure Sensor A Manifold Absolute Pressure Sensor, or MAP, senses the engine load. As it is mounted on the intake manifold it can measure the difference between the intake manifold pressure and outside. This is important for the engine to be able to adjust the fuel injection based on the change in pressure. Spark Knock Sensor A spark knock sensor ensures that the fuel is burning smoothly and not detonating (exploding erratically). Detonation can cause the head gasket to fail, piston lands to crack and rings to break, as well as possible rod bearing damage. Fuel Temperature Sensor The Fuel Temperature Sensor is another sensor that ensures your cars fuel consumption is at its most efficient. The colder the fuel is the more dense and the slower it burns while when the fuel is warm is burns faster. There are many car parts will get damaged when the car runs out of fuel, so this sensor ensures that the right amount of fuel is injected to keep the vehicle running smoothly while being as efficient as possible. Voltage Sensor Another important part in car sensors list is the Voltage Sensor. This sensor manages the idling speed of the car and ensures the speed is increased or decreased as necessary. Coolant Sensor The coolant sensor is probably the most important sensor. Because the computer relies on its input to control other functions. For example, activating or deactivating the Early Fuel Evaporation (EFE) system, spark advance and retard, EGR flow, canister purge etc. This sensor is generally located on the head or intake manifold. Because it is such an important sensor, it can be a problem if the sensor is faulty. If the sensor is faulty, there will be some symptoms like poor fuel mileage, stalling. So the point is that you have to make sure that the coolant sensor is not defective. Vehicle Speed Sensor Just by hearing the name, you can pretty much assume its functionality. But we will explain it anyway. The vehicle speed sensor has the ability to determine the speed of the wheels. It is a kind of tachometer. Throttle Position Sensor The throttle position sensor is used with EFI (electronic fuel injection) and feedback carburetion. It notifies the computer about the rate of throttle opening. Furthermore, it tells the computer about the relative throttle position. The throttle position sensor is mainly a variable resistor. It changes resistance when the throttle opens. It is not difficult to know the symptoms of a faulty throttle position sensor. When there is a stumble during acceleration, you will know that your throttle position sensor is defective. It is the main symptom of a defective throttle position sensor. When you replace the sensor, do not misadjust it. Camshaft Position Sensor The control module uses the camshaft position sensor. It can indicate the position of the number one cylinder. In order to start the sequential fuel injection, the control module uses this piece of information as a reference point.

Types of Engine in Hindi with Animation
 
12:25
The classification of the engines depends upon the types of fuel used, cycle of operation, number of stroke, type of ignition, number of cylinders, arrangement of cylinders, valve arrangement, types of cooling etc. Types of Engine: Basically the engines are of two types, and these are external combustion engines and internal combustion engines. (i). External combustion engine: In external combustion engine, the combustion of fuel takes place outside the engine. Example: steam engine. (ii). Internal combustion engine: In internal combustion engine, the combustion of fuel takes place inside the engine. Two stroke and four stroke petrol and diesel engine are the examples of internal combustion engine. The I.C. engines are classified on the following basis: 1. Types of Design: (i). Reciprocating engine: In reciprocating engine, there is a piston and cylinder, the piston does reciprocating (to and Fro) motion within the cylinder. Due to the reciprocating motion of the piston, it is called reciprocating engine. 2 stroke and four stroke engines are the common examples of reciprocating engine. (ii). Rotary engine: In rotary engine, the rotor does rotary motion to produce power. There is no reciprocating motion. A rotor is present in the chamber which does rotary motion inside a chamber. Wankel rotary engine , turbine engines are the rotary types of engine. 2. Types of Fuel Used: (i). Petrol engine: The engine which uses petrol for its working is called petrol engine. (ii). Diesel engine: The engine which uses diesel for its working is called diesel engine. (iii). Gas engine: An engine using gas fuel for the working is called gas engine. 3.Cycle of Operation: (i). Otto cycle engine: These types of engine works on Otto cycle. (ii). Diesel cycle engine: The engine working on diesel cycle is called diesel cycle engine. (iii). Dual cycle engine or semi-diesel cycle engine: The engine that works on both diesel as well as Otto cycle is called dual cycle engine or semi diesel cycle engine. 4.Number of Strokes: (i). Four Stroke Engine: It is an engine in which the piston moves four times i.e.2 upward (form BDC to TDC) and 2 downward (from TDC to BDC) movement in one cycle of power stroke is called four stroke engines. (ii). Two Stroke Engine: The engine in which the piston does two times motion i.e. one from TDC to BDC and other from BDC to TDC to produce a power stroke is called two stroke engines. 5. Type of Ignition: (i). Spark ignition engine (S.I. engine): In spark ignition engine there is a spark plug which is fitted at the engine head. The spark plug produces spark after the compression of the fuel and ignites the air fuel mixture for the combustion. The petrol engines are spark ignition engine. (ii). Compression ignition engine (C.I. engine): In Compression ignition engine there is no spark plug at the cylinder head. The fuel is ignited by the heat of the compressed air. The diesel engines are compression ignition engine. 6. Number of Cylinders: (i). Single cylinder engine: An engine which consists of single cylinder is called single cylinder engine. Generally the single cylinder engines are used in motorcycles, scooter, etc. (ii). Double cylinder engine: The engine which consists of two cylinders is called double cylinder engine. (iii). Multi cylinder engine: An engine which consists of more than two cylinders is called multi cylinder engine. The multi cylinder engine may have three, four, six, eight, twelve and sixteen cylinder. 7. Arrangement of Cylinders: (i). Vertical engine: in vertical engines, the cylinders are arranged in vertical position as shown in the diagram. (ii). Horizontal engine: In horizontal engines, the cylinders are placed horizontal position as shown in the diagram given below. (iii). Radial engine: The radial engine is reciprocating type internal combustion engine configuration in which the cylinders radiate outward from a central crankcase like the spokes of a wheel. 8. Valve Arrangement: (i). L-head engine: In these types of engine, the inlet and exhaust valves are arranged side by side and operated by a single camshaft. (ii). I-head engine: In I-head engines, the inlet and exhaust valves are located in the cylinder head. A single valve actuates all the valves. (iii). F-head engine: It is a combination of I-head and F-head engines. The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

How a SPARK PLUG works in Hindi
 
07:00
A spark plug is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a porcelain insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode(s).

गाड़ी के EXHAUST / SILENCER से WHITE SMOKE / सफ़ेद धुआँ क्यों निकलता है ? | ENGINE को इससे कैसे बचाये?
 
11:10
Any type of change in the color of the smoke, white smoke from exhaust, for example, is surely a sign that there is a problem with your beloved car. The severity could be varying depending on the type of smoke. The problem might be caused by condensation gathering and may not have any apparent implications. But drivers need to understand, what does white smoke mean? गाड़ी के EXHAUST / SILENCER से BLACK SMOKE / काला धुआँ क्यों निकलता है ? | ENGINE को इससे कैसे बचाये? : https://youtu.be/leTF3wCvdEY What Does White Smoke Mean? White smoke is the issue when your car releases white smoke from exhaust pipe. White smoke can be a big problem or not, depending on the thickness. The white smoke is the result of normal condensation which builds up inside the exhaust system. So if it is thin like vapor, there is nothing to worry about since it will disappear quickly. On the other hand, thicker smoke is a pretty big issue. Thick smoke usually comes from the faulty in engine coolant, which could lead to many serious problems like damaged cylinder head, blown head gasket, cracked engine block… which might cost drivers quite a lot. In this situation, we suggest to not ignore it. A coolant leak, even small, can lead to the serious risk of damage to your dear vehicles. What Your Car Trying To Tell You By White Smoke From Exhaust- 1. Broken Fuel Pumping Injection: Does your car run on diesel? If the answer is positive and if lots of white smoke comes out when starting the engine, it means the fuel pumping injection timing has stopped working. Checking the injection or changing it on your own is not a recommendation from us since this task requires a lot of skills which beginner drivers should not try. Instead of that, without wasting any time have your car checked by a mechanic. 2. Leaking Coolant : Another white smoke issue is the leaking coolant. The indication is apparent when white smoke appears while the car is running, but not when you start it. The reason for this type of white smoke is due to burning coolant that somehow got mixed up. Or else, when your car is lacking coolant, the car may heat up and exhaust white smoke. For that reason, understanding car’s temperature is also very important. Don’t run the car when it’s low on coolant – as that may cause something severer. 3. Problems From Other Parts: Often times, a lot of white smoke exhaustion, when the car is running, could be an indicator of expensive and complicated issues. When the cylinder head, head gasket, fuel filter is damaged, or the engine is clogged or cracked, white gas exhausts in huge amount. Fixing or replacing these parts may be expensive. The problem with such an issue is that you cannot be dilly-dallying. As time goes by they take a severer shape and the cost of repair goes up outright. Regular maintenance helps you to trace out such a problem at the soonest and saves you some valuable cash. How To Fix White Smoke From Exhaust Issue In order to fix white smoke from exhaust problem, besides from taking it to the repair shop, you can do it at home: Step 1: Inspect The Intake Gasket Inside the vehicle, there is a gasket that seals the manifold to the head. These parts take the role of distribution the combustion mixture, along with the coolant to the separated intake port. These ports will be placed in the cylinder heads. You must have understood this now: If it gets damaged, the coolant will get into the port and combustion chamber, creating white smoke while driving. In order to fix it, drivers have to remove the intake manifold and examine the intake gasket. If there is any leak or rust, you know where to repair. If it is fine, we move to step number 2. Step 2: Examine Further To Check The Head Gasket Remember to only perform this step when the intake gasket is working fine. After that, we will come to the head gasket. This is a car part that seals the cylinder head in order to prevent the coolant from getting to the cylinder. Any leak or damage in this part creates an opportunity for the coolant to enter the chamber. Long story short, it will create white smoke from exhaust pipe. If this part is still fine, we will check the cylinder. Step 3: Look For Any Crack In The Cylinder Head The cylinder head is the car part that made of aluminum, which is prone to breaking in overheated conditions. This part is essential since it connects to the engine block and head gasket. Sad news for car owners: If this part is broken or damaged in any way, you have to change it.

CHECK ENGINE LIGHT | Top 10 Reasons for glowing Check Engine Light | How to fix it in Hindi
 
08:06
The orange, engine-shaped icon that sometimes appears in your car’s instrument cluster isn’t just a nuisance — it’s a sign that something is wrong under the hood. Ignoring it could leave you stranded at the worst moment, cost you thousands of rupees, or both. The check engine light warns of issues ranging from a gas cap that’s not properly tightened to a more serious failure like a bad catalytic converter or a problem with one of the car’s oxygen sensors. Here are the 10 most common problems that can trigger a check engine light: 1. OXYGEN SENSOR FAILURE: The oxygen sensor (sometimes called an O2 sensor) measures the amount of unburnt oxygen in a car’s exhaust system. It sends data to the vehicle’s computer, which uses it to regulate the mixture of air and fuel that enters the cylinders. A car will keep running even if an O2 sensor needs to be replaced, but it will burn more fuel than usual. In the long run, a bad O2 sensor can damage components like the spark plugs and the catalytic converter. It may also cause a car to fail an emissions test. 2. LOOSE FUEL CAP: A loose gas cap is one of the most common reasons why the check engine light turns on. The cap is a crucial part of a car’s fuel-delivery system. It notably prevents gasoline fumes from leaving the fuel tank, and it helps keep the whole system under the correct pressure. 3. CATALYTIC CONVERTER FAILURE: A catalytic converter is integrated into a vehicle’s exhaust system. It turns the carbon monoxide generated during the combustion process into carbon dioxide. It’s a fairly simple part, and its failure can often be prevented. 4. SPARK PLUG/IGNITION COIL ISSUES: Put simply, an ignition coil generates the electricity the spark plugs need to ignite the fuel and air mixture in the cylinders. Classic cars have a single coil, but many modern vehicles use one coil per cylinder. If your ride has a V8 under the hood, you could have eight separate coils. The monstrous Bugatti Chiron has 16. No matter how many you have though, a malfunctioning coil will almost certainly trigger the check engine light, but remember, if your car burns diesel, you have neither ignition coils nor spark plugs. 5. BAD SPARK PLUG WIRES: As its name implies, a spark plug wire transfers electricity from the coil to the spark plug. Without it, the fuel and air mixture in the cylinders wouldn’t ignite. A vast majority of cars use a single wire per cylinder, but there are models – notably some older Mercedes-Benzes – with two spark plugs per cylinder, and consequently two wires. Symptoms of bad spark plug wires include a rough idle, a noticeable drop in engine performance, and lower fuel mileage. 6. MASS AIRFLOW SENSOR FAILURE: The mass airflow (MAF) sensor monitors how much air enters the engine. It’s a part of the engine-management system, so your car wouldn’t be able to adjust to changes in altitude without it. Symptoms of an MAF failure include a rough idle, trouble starting, and a sudden change in the position of the throttle pedal. Reduced gas mileage and stalling can also indicate an MAF problem. 7. VACUUM LEAK: Every car has a vacuum system that performs a wide variety of functions. The brake booster is vacuum-operated, and the vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If your car’s idle begins to surge or settles at an unusually high rpm, a vacuum leak could be the culprit. 8. EXHAUST GAS RECIRCULATION VALVE FAILURE: The exhaust gas recirculation (EGR) system lowers the amount of nitrogen oxide that comes out of the car’s engine and helps it run more efficiently. It directs the hot exhaust gases back into the combustion chambers, which warms up the fuel and makes it easier to burn. It also reduces emissions. 9. DEAD BATTERY: The battery is as simple as it is important; without it, your car won’t start, light up the road ahead, or charge your phone. Today’s batteries last much longer than before, and they’re maintenance-free. 10. THERMOSTAT: Thermostat is a crucial component of engine cooling system. The wait is finally over.

What is Bearing? | Types of Bearing in Hindi with Animation
 
13:20
The bearing is a machine element which does the work of reducing friction between two moving parts to get the required motion. The word bearing has been originated from the verb “to bear”. Besides from reducing friction between two rotating parts, bearings also play the role of supporting thrust as well as radial load. 1. Plain Bearing: The plain bearing is the easiest type of bearings, and it is often called as a sliding bearing or slide bearing. The key feature of this bearing is that it consists of only bearing surface and no rolling elements. You can consider a shaft rotating in a hhole as a plain bearing. Pillow block, stuffing box, and ring oiler are the additional elements which are required during the plain bearing. 2. Rolling Element Bearing: It is the type of the bearing in which load is carried out by positioning rolling elements inside the races. Races are nothing but the two bearing rings. Generally, five rolling elements like a cylindrical roller, needle rollers, spherical rollers, tapered rollers, and balls are used as rolling elements in rolling element bearings. Rolling element bearing has two types: A) Ball Bearings: In ball bearing, the gap between the races is kept with the help of the ball. The width of the ball bearing is always less than the diameters of the ball used. Ball bearing again has following types by the load as well as groove cut: (i) Single row ball bearings: As per the name, in this bearing balls are arranged in an identical manner in one row. (ii) Double row ball bearings: They have two rows of balls arranged in a specific manner, and they have two grooves cut. (iii) Angular contact ball bearings: Such bearings are designed to bear angular as well as axial loads. (iv) Thrust ball bearings: Thrust ball bearings are used if you have to handle vertical thrust load. Sometimes, horizontal thrust load can also be operated with this bearing. (v) Self-aligning ball bearings: They are capable of withstanding journal loads. B) Roller Bearing: The roller bearings have higher load bearing capacity than the ball bearings. These bearings have high chances of failures in case of absence of lubricant. Roller bearings are divided into various types by the type of roller used in them: (i) Cylindrical roller bearing: In this type of bearings, a cylinder is used, and it has a higher diameter than its length. (ii) Gear Bearing: This bearing has an arrangement like elliptical gears, and in this bearing, smaller satellite gears are present which perform their revolution around the center of bearing. These bearings increase efficiency as well as it reduces the sliding friction. (iii) Spherical roller bearing: Spherical roller bearing has an inner ring, outer ring, cages, spherical rollers, etc. (iv) Needle roller bearing: A needle roller bearing is made up of long, thin cylindrical rollers and it has the shape like needles. (v) CARB toroidal roller bearing: MangusKellstrom invented the CARB bearing in 1995. The key feature of this CARB toroidal roller bearing is that its radius of curvature is much larger than its possible spherical radius. 3. Jewel Bearing: The main characteristic of the jewel bearing is that metal spindle is turned into a jewel-lined pivot hhole. The benefits of the jewel bearings have small weight as well as size, low friction and their ability to work without any lubrication. 4. Fluid Bearing: A fluid bearing is a special type of bearing in which there is no sliding friction, wear or any vibrations. Fluid bearings have two types hydrostatic and hydrodynamic. (i) Hydrodynamic fluid bearings: This bearing depends on the part of the shaft resting on the fluid to pressurize fluid between its surfaces. This type of bearings is generally used in the electric motors, hydroelectric generators, cooling pumps, etc. (ii) Hydrostatic fluid bearings: The important feature of the hydrostatic fluid bearings is that they can handle heavy loads at the low speeds. They are more durable bearings, and therefore, they have a longer life. 5. Magnetic Bearing: In the magnetic bearing, the phenomenon of magnetic levitation is used to support the load. Compressors, turbines, pumps, motors, as well as generators, use the magnetic bearings. Nowadays, they are highly used in artificial hearts. 6. Flexure Bearing: In the flexure bearing, a flexible element is manufactured in such a way that, it is suitable in specific degrees of freedom.

गाड़ी के EXHAUST / SILENCER से BLACK SMOKE / काला धुआँ क्यों निकलता है ? | ENGINE को इससे कैसे बचाये?
 
04:31
The diesel engines are well-known for producing the black smoke, and that makes them ugly to drive. The reasons are many, and so are the solutions on the diesel black smoke. In this video, i have explained about all the reasons for producing black smoke and how can you protect your vehicle from 'Black Smoke'. गाड़ी के EXHAUST / SILENCER से WHITE SMOKE / सफ़ेद धुआँ क्यों निकलता है ? | ENGINE को इससे कैसे बचाये? : https://youtu.be/tnmVIz5qvGA The Reasons For Getting The Diesel Black Smoke : 1. The Imperfect Air To Fuel Ratio: The primary reason can be the imbalanced amount of air and fuel. When the fuel does not get enough air or if there is not enough oxygen, the engine produces soot that comes out as diesel black smoke. This can be a case of the faulty injector that injects the fuel into the combustion area. The malfunctioning injector makes the engine droplets spread improperly in the cylinder. 2 The Accumulation Over Time: With time, the engine gets an accumulation of dust, debris, and other engine particles. These accumulations if enter major areas like injector or combustion create the issue and make the engine to malfunction. As a result, the path gets obstructed, and you see the black smoke from diesel engine when accelerating. 3. When The Piston Rings Malfunction: The piston rings keep the engine oil from meeting the combustion chamber. Over time, these rings may wear out, and hence the engine oil starts flowing in the combustion zone. As a result, it creates an undesired mixture that should not be there and burning the mixture produces the black smoke like effect. Remedies To Reduce Or Eliminate The Issue: 1. Make A Purchase For The Engine Flush: You can buy the engine flush from any vehicle shop and flush the engine to smoothen it. Like its name, the flush clears out any blockage in the passage that contributes to maintaining a proper balance of air and fuel. 2. Cool Down The Engine During Long Rides: Long drives can be another reason for black smoke from exhaust diesel where the engine burns out as hot. So, during the long drives, give some rest to your car by shutting it off, and after a few minutes, you can continue riding. 3. Consider The Mechanical Help: If you can’t figure out things on your own, it is wise to call the mechanic or take your car there. Let him check out for any parts that are worn out and have a replacement for the same. The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

गाड़ी का Brake Pad कितने Thickness पे Change करे? | Brake Pad Thickness: What Is The Minimum Depth?
 
07:16
The correct brake pad thickness is vital for not only the engine’s proper operation but also the road safety. Replacing the pads at the right time will save plenty of your money down the road. But, at what thickness should brake pads be replaced? How to correctly do the brake pad measurements and take necessary action? In this video i have explained all the necessary points. What Are Brake Pads? Brake pads, which sit between the brake shoe and brake drum, are crucial to the brake system of a vehicle. If these are damaged or don’t have the required thickness, other components of the brake system – rotors, calipers, and discs – will be wearing out. It’s important to figure out the right time to replace the pads to avoid unsafe driving conditions. Brake Pad Thickness: The Minimum And Recommended Limits- Brake pads are made of steel plates, shims, and friction materials. There are two layers of rubberized coating and thermal insulation coating on the outside. Like all other things, these materials wear out over time. Also, rough driving and poor road conditions play a part in hastening the deterioration. The normal lifespan of brake pads is anywhere between 30,000 – 35,000 miles. However, it can be even more or less depending on the car’s make and model, driving habit, and road conditions. New Brake Pad Thickness- So, how thick are brake pads when they are purchased new? Well, the new brake pad depth is approximately 12 mm. This is the standard thickness and it will last more or less 35,000 miles. If you are an aggressive driver that uses the brake often, they will not last long. Also, they get a shorter lifespan than usual when you have to engage the brake frequently due to heavy commuter traffic. Minimum Brake Pad Thickness- Mechanics suggest replacing brake pads because continuous engagements make their friction material become thin. When the material rubs away completely, the next stage is the failure of the brake. The brake pad thickness has to be at least 6.4 mm or more for its proper functioning. You can get away with thinner pads sometimes. But, quick replacement when the thickness is between 6.4 to 3.2 mm will save the brake system from severe damage. The Symptoms Of Thin Brake Pads- A physical inspection is enough to check whether the pads are within the recommended thickness. You will need just a flashlight, inspection mirror, and measuring gauge to do it. Metallic grinding or growling sound, which comes when brake discs and calipers rub against each other. It means that the pads are completely worn out. Screeching, squealing, or whining noises when you engage the brakes. If the sound does not go away after a couple of times, you have to check the brake pads. Some cars have an indicator light on the dash to give a thin-pad warning. The wait is finally over.

बाइक में डीजल इंजन का उपयोग क्यों नहीं किया जाता है? | Why Diesel Engines are not Used in Bikes?
 
05:14
We all are bike lovers. We use bike many times in a day. Usually bike is run by petrol. The price of petrol is higher than diesel in many countries. Sometimes we think, why bike is not run by diesel. If there is a diesel bike than we can save some money. Today I am going to tell you some reasons why diesel engines are not used in bikes. 1. Diesel engine has a compression ratio 24:1, which is higher than petrol engine compression ratio of 11:1. Diesel engine must be bigger and of heavy metal in order to handle this high compression ratio. That’s why the diesel engine is heavier than petrol engine and not suitable for small vehicle like motorcycle. 2. Due to high compression ratio, diesel engine produces more vibration and noise as compared to the petrol engine. It is not possible for a light vehicle to handle this high vibration and noise.That’s why diesel engines are not used in motorcycle. 3. Due to high compression ratio and heavy engine, initial price of the diesel engine is more than the petrol engine. And this initial price difference is about 50,000 rupees, which is not suitable for small vehicle 4. Diesel engine produces approximately 13% more carbon-di-oxide per gallon as compared to the petrol engine. So it makes greater pollution than petrol engine and it is not good to use for environment. 5. Diesel engine works on high pressure, so wear and tear is high in diesel engines. To reduce this wear and tear oil change are frequently required at every 5,000 kilometer instead of 10,000 kilometer in the case of petrol engine. 6. Diesel engine produces more torque but low rpm than petrol engine. So in bikes where we need high speed, it is not suitable. 7. Diesel has high energy per gallon as compare with the petrol. When diesel burns, it produces a large amount of heat which can destroy walls of the cylinder and other parts of the engine. So to reduce this heat, we need a greater surface area and proper cooling system. In order to achieve this greater surface area, the engines are made slightly bigger. 8. Diesel engine uses turbocharger or supercharger to pump more air into the cylinder, which increases its price and size. 9. In diesel engines, injector technology is used to inject fuel into the combustion chamber, which is more expensive than spark plug technology of petrol engine. 10. Diesel engine is very big as compared with the petrol engine and it uses high power starting motor to crank the engine, which is not suitable for motorcycles. The wait is finally over.

How Cars's Airbags Technology Works? | Car का Airbag कैसे काम करता है ?
 
04:54
An airbag is more correctly known as a supplementary restraint system (SRS) or supplementary inflatable restraint (SIR). The word "supplementary" here means that the airbag is designed to help the seat belts protect you rather than replace them (relying on an airbag to protect you without fastening your seat belt is extremely dangerous). The basic idea is that the airbag inflates as soon as the car starts to slow down in an accident and deflates as your head presses against it. That's important: if the bag didn't deflate, your head would just bounce back off it and you'd be no better off. How airbags work - 1. When a car hits something, it starts to decelerate (lose speed) very rapidly. 2. An accelerometer (electronic chip that measures acceleration or force) detects the change of speed. 3. If the deceleration is great enough, the accelerometer triggers the airbag circuit. Normal braking doesn't generate enough force to do this. 4. The airbag circuit passes an electric current through a heating element (a bit like one of the wires in a toaster). 5. The heating element ignites a chemical explosive. Older airbags used sodium azide as their explosive; newer ones use different chemicals. 6. As the explosive burns, it generates a massive amount of harmless gas (typically either nitrogen or argon) that floods into a nylon bag packed behind the steering wheel. 7. As the bag expands, it blows the plastic cover off the steering wheel and inflates in front of the driver. The bag is coated with a chalky substance such as talcum powder to help it unwrap smoothly. 8. The driver (moving forward because of the impact) pushes against the bag. This makes the bag deflate as the gas it contains escapes through small holes around its edges. By the time the car stops, the bag should have completely deflated. The wait is finally over.

In order to draw the cam profile for a radial cam, first of all the displacement diagram for the given motion of the follower is drawn. Then by constructing the follower in its proper position at each angular position, the profile of the working surface of the cam is drawn. In constructing the cam profile, the principle of kinematic inversion is used, i.e. the cam is imagined to be stationary and the follower is allowed to rotate in the opposite direction to the cam rotation.

CENTRIFUGAL GOVERNOR | Components, Function and Working in Hindi
 
08:34
The function of a governor is to regulate the mean speed of an engine, when there are variations in the load e.g. when the load on an engine increases, its speed decreases, therefore it becomes necessary to increase the supply of working fluid. On the other hand, when the load on the engine decreases, its speed increases and thus less working fluid is required. The governor automatically controls the supply of working fluid to the engine with the varying load conditions and keeps the mean speed within certain limits. 'The 3D Models, Animations and Images are courtesy of https://savree.com/'. A little consideration will show, that when the load increases, the configuration of the governor changes and a valve is moved to increase the supply of the working fluid ; conversely, when the load decreases, the engine speed increases and the governor decreases the supply of working fluid. The centrifugal governors are based on the balancing of centrifugal force on the rotating balls by an equal and opposite radial force, known as the controlling force. It consists of two balls of equal mass, which are attached to the arms .These balls are known as governor balls or fly balls. The balls revolve with a spindle, which is driven by the engine through bevel gears. The upper ends of the arms are pivoted to the spindle, so that the balls may rise up or fall down as they revolve about the vertical axis. The arms are connected by the links to a sleeve, which is keyed to the spindle. This sleeve revolves with the spindle ; but can slide up and down. The balls and the sleeve rises when the spindle speed increases, and falls when the speed decreases. In order to limit the travel of the sleeve in upward and downward directions, two stops S, S are provided on the spindle. The sleeve is connected by a bell crank lever to a throttle valve. The supply of the working fluid decreases when the sleeve rises and increases when it falls. When the load on the engine increases, the engine and the governor speed decreases. This results in the decrease of centrifugal force on the balls. Hence the balls move inwards and the sleeve moves downwards. The downward movement of the sleeve operates a throttle valve at the other end of the bell crank lever to increase the supply of working fluid and thus the engine speed is increased. In this case, the extra power output is provided to balance the increased load. When the load on the engine decreases, the engine and the governor speed increases, which results in the increase of centrifugal force on the balls. Thus the balls move outwards and the sleeve rises upwards. This upward movement of the sleeve reduces the supply of the working fluid and hence the speed is decreased. In this case, the power output is reduced. The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.

What is Firing Order of 2, 3, 4, 6 and 8 Cylinder Engine in Hindi
 
10:06
Firing order of a multi cylinder engine is the power delivering sequence of each cylinder which is set by the designer such that the combustion of fuel in different cylinders occurs in a predefined order that can produce uninterrupted and maximum power output through the crankshaft of an multi-cylinder engine. (i) In-Line 2 cylinder engine of a Tata Nano – In Tata Nano, 2-cylinder in-line engine is used even being the more than 1-cylinder engine, firing order is not so complex as it is quite obvious that when cylinder 1 will get firing or the spark plug ignition than the cylinder 2 will be at compression stroke and the order of the firing will be 1-2. (ii) In-Line 4 cylinder engine of a Maruti Suzuki Swift– In cars like swift having 4-cylinders placed in a straight line, the firing order is configured as 1-3-4-2 which means all the cylinders will have firing or the spark plug ignition according to the 1-3-4-2 sequence, it is found that in a 4 cylinder engine a complete firing order gives 720 degrees of the crankshaft rotation which means each power stroke by the individual piston gives 180 degree of rotation to the crankshaft. All the 4 cylinders in In-line 4 cylinder engine are mounted over four pins of the crankshaft placed in every 180 degree of the crankshaft. For the smooth working of a 4-cylinder engine it is required that each cylinder will have different stroke at any instant. For example- At any instant in a inline 4-cylinder engine usually it is seen that when cylinder 1 is having power stroke than cylinder 4 is usually seen to be suction stroke, cylinder 2 and cylinder 3 are usually seen to be at exhaust and compression stroke respectively. (iii) V-Shape 2 cylinder engine of a Harley Davidson Iron 833 bike- In Harley Davidson Iron 833, 2-cylinder engine placed in V-shape is used in which same firing order as in-line 2-cylinder engine mentioned above is used i.e. 1-2. (iv) V-Shape 6 cylinder engine of Honda Accord- In the high end cars line Honda Accord and Audi A-8, high power engine having multiple cylinders are used as in Honda Accord, 6 cylinder engine placed in V-shape is used in which a proper and effective firing order is required. The firing order in Honda Accord ( 6-cylinders placed in V-shape such that cylinder 1,2,3 are placed in left hand side and 4,5,6,are placed in right) is configured as 1-5-3-6-2-4. Firing order 1-5-3-6-2-4 means the crank pins having piston mounted are arranged in every 60 degree of the crankshaft. As the power impulse is generated in every 720 degree rotation of the crankshaft which means that power stroke in V6 engine is obtained in every 120 degree rotation of the crankshaft. (v) Flat-six cylinder engine used in Porsche 911 GT3- In some cars like Porsche 911 GT3 6- cylinders placed in horizontal plane having opposite direction i.e. cylinder 1,2,3 are placed in left side and cylinder 4,5,6 are arranged in right side, are used. same as the V6 engine all the pistons are mounted over 6 crank pins placed in every 60 degree of the crankshaft. The firing order of this type of engine is configured as 1-4-5-2-3-6 which means that the firing or spark ignition will occur at every 120 degree of the crankshaft rotation. The wait is finally over.
