It’s generally of two types compression rings and oil control rings.ĩ) Spark plug: It is used in petrol engines for the ignition of compressed charge.ġ0) Fuel injector: It is used in diesel engines to spray fuel into the Compressed air.ġ1) Connecting rod and crank: The main purpose of connecting rod and crank is to convert the reciprocating motion of the piston to the rotary motion of the crankshaft. It avoids leakage of gases from the combustion chamber to the crankcase. The movement of the outlet valve is also controlled by the camshaft.Ĩ) Piston rings: Piston rings are used to seal the combustion chambers. It opens only at exhaust stroke and remains closed in others strokes.
The movement of the inlet valve is controlled by the camshaft.ħ) Exhaust valve: the exhaust valve is used to control the flow of burned exhaust gases.
It opens only at a suction stroke and remains closed in other strokes. The main purpose of the intake manifold is to supply the charge equally in multi-cylinder engines.ĥ) Exhaust manifold: The exhaust gases from the cylinder are expelled out through the exhaust manifold.Ħ) Inlet valve: The inlet valves are used to control the flow of fresh charge into the cylinder. It is generally made up of aluminum alloy.Ĥ] Inlet manifold: The fresh charge is supplied to the cylinder from the intake manifold. The other end of the piston is connected to the connecting rod.
The intake and exhaust manifold are connected to the cylinder head.ģ] Piston: It is a reciprocating element that reciprocates into the cylinder. The piston moves inside of the cylinderĢ] Cylinder head: The valves and spark plug/fuel injector is mounted onto the cylinder head. 1] Cylinder: A cylinder is generally made up of cast iron.
