Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston.
It is in direct contact with the products of combustion so it must be cooled. For cooling of cylinder a water jacket for liquid cooling used in most of cars or fin for air cooling used in most of bikes are situated at the outer side of cylinder. At the upper end of cylinder, cylinder head and at the bottom end crank case is bolted. The upper side of cylinder is consists of a combustion chamber where fuel burns.
So it is made by high grade cast iron. It is made by casting and usually cast in one piece. Cylinder Head: - The top end of cylinder is closed by means of removable cylinder head. There are two holes or ports at the cylinder head, one for intake of fuel and other for exhaust. Both the intake and exhaust ports are closed by the two valves known as inlet and exhaust valve. The inlet valve, exhaust valve, spark plug, injector etc.
The main function of cylinder head is to seal the cylinder block and not to permit entry and exit of gases on cover head valve engine. Cylinder head is usually made by cast iron or aluminum.
It is made by casting or forging and usually in one piece. Piston: - Piston is considered as the heart of an I. It is fitted to each cylinder as a face to receive gas pressure and transmit the thrust to the connecting rod. It is the prime mover in the engine. The main function of piston is to give tight seal to the cylinder through bore and slide freely inside of cylinder.
Piston should be light and sufficient strong to handle the gas pressure generated by combustion of fuel. So the piston is made by aluminum alloy and sometimes it is made by cast iron because light alloy piston expands more than cast iron so they need more clearances to the bore. Piston Rings: - A piston must be a fairly loose fit in the cylinder so it can move freely inside the cylinder. If the piston is too tight fit, it would expand as it got hot and might stick tight in the cylinder and if it is too loose it would leaks the vapor pressure.
To provide a good sealing fit and less friction resistance between the piston and cylinder, pistons are equipped with piston rings. These rings are fitted in grooves which have been cut in the piston. They are split at one end so they can expand or slipped over the end of piston.
A small two stroke engine has two piston rings to provide good sealing but in a four stroke engine has an extra ring which is known as oil ring. Piston rings are made of cast iron of fine grain and high elastic material which is not affected by the working heat. Sometimes it is made by alloy spring steel. Connecting Rod: - Connecting rod connects the piston to crankshaft and transmits the motion and thrust of piston to crankshaft.
It converts the reciprocating motion of the piston into rotary motion of crankshaft. There are two end of connecting rod one is known as big end and other as small end. Big end is connected to the crankshaft and the small end is connected to the piston by use of piston pin. The connecting rods are made of nickel, chrome, and chrome vanadium steels. For small engines the material may be aluminum.
Crank Shaft: - The crankshaft of an internal combustion engine receives the efforts or thrust supplied by piston to the connecting rod and converts the reciprocating motion of piston into rotary motion of crankshaft. The crankshaft mounts in bearing so it can rotate freely. The shape and size of crankshaft depends on the number and arrangement of cylinders. It is usually made by steel forging, but some makers use special types of cast-iron such as spheroidal graphitic or nickel alloy castings which are cheaper to produce and have good service life.
Cam Shaft: - Camshaft is used in IC engine to control the opening and closing of valves at proper timing. For proper engine output inlet valve should open at the end of exhaust stroke and closed at the end of intake stroke.
So to regulate its timing, a cam is use which is oval in shape and it exerts a pressure on the valve to open and release to close. It is driven by the timing belt which drives by crankshaft. It is placed at the top or at the bottom of cylinder. It takes driving force from crankshaft through gear train or chain and operates the inlet valve as well as exhaust valve with the help of cam followers, push rods and rocker arms.
Gudgeon Pin: - These are hardened steel parallel spindles fitted through the piston bosses and the small end bushes or eyes to allow the connecting rods to swivel. It connects the piston to connecting rod. It is made hollow for lightness. It is made of steel. Crank Case: - The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearing is called crankcase. It serves as the lubricating system too and sometime it is called oil sump.
All the oil for lubrication is placed in it. Fly wheel: - Fly wheel is a rotating mass used as an energy storing device. A flywheel is secured on the crankshaft. The main function of flywheel is to rotate the shaft during preparatory stroke. It also makes crankshaft rotation more uniform. It is done by storing excess energy during the power strokes, which is returned during other strokes.
The number of valves in an engine depends on the number of cylinders. Two valves are used for each cylinder one for inlet of air-fuel mixture inside the cylinder and other for exhaust of combustion gases.
The valves are fitted in the port at the cylinder head by use of strong spring. This spring keep them closed. Both valves usually open inwards. Governor: - As the name indicates, it controls the speed of engine by controlling the fuel supply. It controls the speed of engine at a different load by regulating fuel supply in diesel engines. In petrol engines, supplying the mixture of air-petrol and controlling the speed at different load conditions.
Spark plug: - It is used in petrol engine only. The main function of a spark plug is to ignite the compressed air fuel mixture. It is fitted on cylinder head. The spark plug consists of a metal shell having two electrodes which are insulated from each other with an air gap.
Carburetor: - It is a small but the important part of engine. It converts petrol in fine spray and mixes with air in proper ratio as per requirement of engine.
Internal combustion engines come in a wide variety of types, but have certain family resemblances, and thus share many common types of components. Internal combustion engines can contain any number of combustion chambers cylinders , with numbers between one and twelve being common, though as many as 36 Lycoming R have been used. Having more cylinders in an engine yields two potential benefits: first, the engine can have a larger displacement with smaller individual reciprocating masses, that is, the mass of each piston can be less thus making a smoother-running engine since the engine tends to vibrate as a result of the pistons moving up and down. Doubling the number of the same size cylinders will double the torque and power. The downside to having more pistons is that the engine will tend to weigh more and generate more internal friction as the greater number of pistons rub against the inside of their cylinders. This tends to decrease fuel efficiency and robs the engine of some of its power.
Automobile engines are complicated mechanisms that are made up of several internal parts that work like clockwork to produce that power that moves your vehicle. In order for the engine to operate properly it needs all of its parts to be in good condition. One fault can be disastrous! Let's take a look at the main parts of the engine. The block is the main part of the engine. All other parts of the motor are essentially bolted to it. Inside the block is where the magic happens, such as combustion.
List of Car Engine Parts: Its Function (With Pictures). By The internal combustion engine is those heat engines that burn their fuel inside the.
This is a list of automotive parts , mostly for vehicles using internal combustion engines which are manufactured components of automobiles :. From Wikipedia, the free encyclopedia. Wikipedia list article.
In this post, we will discuss the engine parts. The engine has two types one is the internal combustion engine and another one is the external combustion engine. The engine most essential part of automobile industries or we can say that the engine is the heart of an automobile.
Just like humans in order to move, your engine requires energy. In fact, the core responsibility of the engine is to transform energy from fuel with a spark, to create the power to move. This internal combustion creates tiny, contained explosions to produce movement. Car engines are designed around sealed, resilient metal cylinders.
Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated. You might want to know what's going on simply out of curiosity. Or perhaps you are buying a new car , and you hear things like "2.
A Reciprocating Engine is a classification of the internal combustion engines in which the piston moves up and down. The top portion of the piston where valves are located is called Top dead center , and the opposite extreme down portion of the piston is called Bottom dead center. The air or air-fuel mixture is drawn into the cylinder through the Intake valve and the combustion products are expelled from the cylinder through the Exhaust valve. This is the powerhouse of the vast majority of automobiles such as trucks, aircraft, ships, electric power, generator and so on. The minimum volume formed in the cylinder when the piston is at TDC is called Clearance volume.
Сьюзан на мгновение заколебалась и оглянулась на заблокированную дверь. Всего двадцать минут, подумала. Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла. Она подумала, что дело, быть может, в неисправном ионизаторе воздуха. Запах показался ей смутно знакомым, и эта мысль пронзила ее холодом.
Пора было отсюда вылезать.
