汽车柴油机耐久试验方法与活塞典型失效模式浅析

Analysis on Durability Test Methods of Diesel Engine and Classic Failure Model of Piston

当今柴油机不仅具有动力性强、省油的特点,而且排放和振动噪声水平也得到极大的提升,越来越多的车型已搭载柴油机作为动力源,并且这种趋势正在逐渐扩大,因此对汽车用柴油机的可靠性和耐久性提出了更高的要求。结合实际工作情况,介绍柴油机耐久试验方法,简要分析活塞的典型失效模式。

Not only diesel engine has the characteristic of stronger power and saving fuel,but also the emission and NVH are improved greatly. Diesel engine is more and more taken as vehicles power,so higher requirements are raised for diesel engine＇s reliability and durability. According to actual working condition,reliability testing methods for diesel engine and classic failure model analysis for piston were introduced.
