Engine Spare Parts V2203 Overhaul Kit Piston Piston Ring Set Liner Kit for Kubota Excavator Diesel Engine
In addition, the installation is subject to greater preload. The gas pressure makes the cylinder wall produce tangential tensile stress and radial compressive stress, and the inner surface is larger, such stress is high frequency pulsation stress.
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.
