introduction：neiranji shouming Internal combustion engine life service life of internal combustion engine The period from the beginning of the internal combustion engine to the time when it does not work properly。There are different understandings of the life of internal combustion engines，One refers to the whole life of the internal combustion engine from the beginning of use to the end of damage；The other refers to the overhaul life from the beginning of use to the first overhaul。Major parts need to be repaired and replaced during overhaul，After many overhauls, the whole life is no longer meaningful，So people usually pay more attention to overhaul life。
