The cylinder liner forms the cylindrical surface along which the piston and piston rings slide. It maintains the correct geometry of the cylinder, transfers heat to the engine block, and allows the engine to be rebuilt without having to replace the entire engine block. It is specified as a flanged cylinder liner and is supplied without sealing rings.
Cummins 6C-Series engines are also used in power plants, including the ISC 8.3, QSC 8.3, ISL 8.9 / 9, and QSL 8.9 / 9 models.

It is mounted in the engine block and directs a jet of oil toward the bottom of the piston, helping to reduce its temperature and lubricate the piston-cylinder assembly. It is located in the cylinder block, where its function is to spray oil under the piston for cooling and lubrication. It is made of metal, primarily steel.
