引言现代高增压四冲程柴油机的气缸套承受很高的热负荷和机械负荷。负荷一方面来自工作过程中柴油机燃烧室中燃气的温度和压力,另一方面来自缸套在气缸盖—气缸套—机体预应力安装中的压装条件。 Introduction Cylinder liners for modern high-pressure, four-stroke diesel engines are subject to high thermal and mechanical loads. The load on the one hand comes from the temperature and pressure of the fuel gas in the combustion chamber of the diesel engine during operation and on the other hand from the conditions of press-fit of the cylinder liner in the cylinder head-cylinder liner-body pre-stressing installation.
