内燃机动力装置的使用寿命总的说来取决于装置中最重要组成部分的耐久性。装置中最重要的组成部分当然是内燃机,而内燃机的使用寿命又与结构、工艺、运动、动力等大量因素以及其它特性有关。这些因素因其本身的物理性质各异,而使内燃机的零部件受到不同程 The life of an internal combustion engine powerplant depends, in general, on the durability of the most important component of the installation. The most important part of the installation is, of course, the internal combustion engine, which, in turn, has to do with the large number of factors such as structure, workmanship, movement, power and other characteristics. These factors because of their different physical properties, leaving internal combustion engine parts are subject to different procedures
