Engine Spare Parts  4D84 Overhaul Kit Piston Piston Ring Set Liner Kit for Yanmar

The inner surface of the cylinder liner is directly affected by the high-temperature and high-pressure gas, and the 6-cylinder liner assembly is always in high speed sliding friction with the piston ring and piston skirt. Surface contact with the cooling water, in the larger temperature difference under the serious thermal stress, by the cooling water corrosion.

Because of the temperature difference between the inside and outside of the cylinder wall, the thermal stress is extremely great. However, at extremely high temperatures, the metal near the inner surface is subject to creep plastic deformation, while the residual tensile stress is formed on the inner surface after cooling.

The low-frequency stress caused by changes in starting and stopping will fatigue the material.

The cylinder liner is a cylindrical part placed in the cylinder block hole of the engine body and held in place by the cylinder head. The piston reciprocates in its inner hole and has cooling water outside.
