About the product

Working conditions of cylinder liner

The inner surface of the cylinder liner is directly affected by high-temperature and high-pressure gas, and always experiences high-speed sliding friction with the piston ring and piston skirt. The appearance comes into contact with cooling water, causing severe thermal stress under large temperature differences and corrosion by the cooling water. The lateral thrust of the piston on the cylinder liner not only intensifies its internal friction, but also causes it to bend. When the lateral thrust changes direction, the piston also hits the cylinder liner. In addition, it is subjected to significant installation preload force.

The gas pressure causes tangential tensile stress and radial compressive stress on the cylinder wall, with the maximum stress occurring on the inner surface, all of which are high-frequency pulsating stresses.

Due to the temperature difference between the inside and outside of the cylinder wall, significant thermal stress is generated, resulting in compressive stress on the inner surface and tensile stress on the cooling surface at normal temperatures. But at extremely high temperatures, the metal near the inner surface undergoes creep plastic deformation, and residual tensile stress is formed on the inner surface after cooling. This low-frequency stress caused by changes in starting and stopping can cause material fatigue.
