Cylinder Liner


a replaceable cylindrical insert mounted in the block of water-cooled reciprocating heat engines. Cylinder liners are made of cast iron and are used in aluminum-alloy blocks to reduce the wear on friction surfaces and to facilitate repair. The cylinder liner determines the displacement of the cylinder in which the piston is housed. The inner surface of a cylinder liner is carefully machined and polished, and the outside of the liner is cooled with water, which circulates in the water jacket of the engine block.
