PistonДЄ piston is fitted to each cylinder as a face to receive gas pressure and transmit the thrust to the connecting rod. It is made by casting or forging and usually in one piece. Cylinder head is usually made by cast iron or aluminum. The main function of the cylinder head is to seal the cylinder block and not to permit entry and exit of gases on the cover head valve engine. The inlet valve, exhaust valve, spark plug, injector, etc. Both the intake and exhaust ports are closed by the two valves known as inlet and exhaust valve. There are two holes or ports at the cylinder head, one for the intake of fuel and another for exhaust. The top end of the engine cylinder is closed by means of the removable cylinder head. It is made by casting and usually cast in one piece. To handle all this pressure and temperature generated by the combustion of fuel, cylinder material should have high compressive strength. The upper side of the cylinder is consisting of a combustion chamber where fuel burns. The cylinder head and crankcase at the bottom end of the cylinder are fixed at the top end of the cylinder. When cooling a cylinder, on the outer side of the cylinder there is a water jacket (when liquid cooling used in most cars) or fin (for air cooling used in most bikes). It is in direct contact with the combustion products, so it has to be cooled. The main function of the cylinder is to guide the piston. The cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. Cylinder blockДЄ cylinder is the main body of the IC engine. This engine easily starts in cold because it uses high volatile fuel.Д¬OMPONENTS OF IC ENGINE 1.These engines are compact and required less space.It has overall high efficiency over the E.C.These engines are generally used in automobile industries, generation of electric power, etc. In these engines, we can use only gases and high volatile fuel like petrol, diesel.

This high-pressure force is exerted on the piston (A device that frees to moves inside the cylinder and transmits the pressure force to crank by use of connecting rod), which used to rotate the wheels of the vehicle. When the fuel burns inside the engine cylinder, it generates a high temperature and pressure. It is an engine in which the combustion of fuel takes place inside the engine.
