ENGINE CYLINDER LINER PARTS FOR S6D125 OEM 6150-21-2221;6151-21-2220

Cylinder liner is the abbreviation of engine cylinder liner, which is embedded in the cylinder of the cylinder block and forms the combustion chamber with the piston and cylinder head.
Cylinder liners are divided into two categories: dry liners and wet liners. The cylinder liner whose back side does not contact the cooling water is called a dry cylinder liner, and the cylinder liner whose back side is in contact with the cooling water is a wet cylinder liner. The thickness of the dry cylinder liner is thin, the structure is simple, and the processing is convenient. The wet cylinder liner directly contacts the cooling water, so it is conducive to the cooling of the engine, which is conducive to the size and weight of the engine.
