Cavitations Of Liners

Cavitations of liner is caused by vibration generated by piston bouncing against cylinder wall , particularly in the region of piston dead center. This causes the water jacket to vibrate too. When the cylinder wall gives in during the vibration phase, a vacuum a generated in cylinder for short time, and vapor bubblers will form consequently.


When the column swings back, these bubbles collapse. The water forced against the surface and erodes the metal.
