一、前言水冷四冲程柴油机缸套和缸体上,有时发生穴蚀损伤,严重时使缸套和缸体穿通而引起重大事故。目前,愈来愈强烈地要求柴油机轻量,高速、大功率化,因此穴蚀现象就成为一 I. Introduction Water-cooled four-stroke diesel engine cylinder liner and cylinder, and sometimes cavitation damage occurs, so serious when the cylinder liner and cylinder piercing caused a major accident. At present, diesel engines are increasingly required to be light-weight, high-speed, and high-power, thus causing cavitation to become one
