Piston rings are circular metal rings that fit around the outer diameter of a piston. They have several important functions:

Sealing: Piston rings create a seal between the cylinder and the piston. This helps prevent exhaust gases from leaking into the crankcase and oil from entering the combustion chamber.

Heat Transfer: They help transfer heat away from the piston to the cylinder wall.

Lubrication: Piston rings help distribute oil along the cylinder walls, ensuring proper lubrication.

Support: They help support the piston as it moves up and down in the cylinder.

In an engine, you typically have multiple rings on each piston, including compression rings and oil control rings. The compression rings are responsible for sealing the combustion chamber, while the oil control rings help prevent excessive oil from entering the combustion chamber Cylinder liners, also known as cylinder sleeves, are cylindrical metal components that are inserted into an engine block to provide a wear-resistant surface for the piston to move up and down within the cylinder. They help protect the engine block from wear and tear caused by the piston movement.
