The Piston rings near the head are called вЂњcompression ringsвЂќ and those away from the compression ring are called вЂњoil ringsвЂќ. The Piston rings are made of special quality cast iron which can retain its elastic property event at high temperature. The Piston rings provide gas-tight fitted between the Piston and the cylinder so that leakage of high-pressure gas is prevented. Piston rings are accommodated in the grooves provided around the outer surface of the piston. Piston rings are known as the compression ring. A number of piston rings are fitted in the groups towards the top of the Piston to prevent the leakage of charge passes the piston. engines moving to the end inside the cylinder are known as trunk pistons.

The cylinder body contains the passage for the inlet and outlet of the gases. And atomizer is fitted with the cylinder on the head and side of the Piston through studs and nuts. A cylinder head containing the spark plug. In the case of water, it is sufficient to replace the liner. For smaller engines the cylinder with water jacket is cast in one block for a large engine, however cylinder liners are used with the main cylinder. In the case of a large engine, all the cylinders are cast in one block. The cylinders of internal combustion generally made of cast iron and Nickel cast iron.
