A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head. Pistons are commonly made of a cast aluminum alloy for excellent and lightweight thermal conductivity.
The cylinder liner or sleeve or bore provides the engine with the cylindrical structure needed to confine the combustion gasses and to act as a guide for the engine’s pistons. In engines using sleeves, there are two types of sleeves, wet and dry.
The valve which allows mixture into the cylinder is the inlet valve; the one through which the spent gases escape is the exhaust valve. They are designed to open and close at precise moments, to allow the engine to run efficiently at all speeds.

The oil pumps primary purpose is to circulate engine oil under pressure to the bearings, pistons and the camshaft. This lubricates these systems, allows the use of higher-capacity fluid bearings and also assists in engine cooling.
