The dry cylinder liner has a thinner thickness, simple structure and convenient processing. The wet cylinder liner is in direct contact with the cooling water, so it is beneficial to the cooling of the engine, and is conducive to the miniaturization and weight reduction of the engine.
Cylinder failure type
