目前对同类型,但其功率各不相同,且工作条件亦异的柴油机搞系列化,已得到了普遍推广。因此,对某一变型柴油机,制订出其第一次大修期的评定方法,并将其应用于整个系列柴油机上,引起人们的兴趣。分析以往的研究成果表明,多数研究者在评定柴油机大修期时,是考虑负荷 P_e 和速度 C_m Currently on the same type, but its power is different, and different working conditions of diesel engine series, has been widely promoted. Therefore, for a certain variant diesel engine, the assessment method of its first overhaul period was formulated and applied to the whole series of diesel engines, arousing people’s interest. Analysis of past research results show that most researchers in the assessment of diesel overhaul period, is to consider the load P_e and speed C_m
