摘　　要：尾气成分与发动机的工况有最直接的联系,通过实验总结出发动机各部分技术状况与尾气成分间的关系,分析了尾气成分异常的原因。指出通过尾气分析可诊断出发动机故障所在的部位,并通过故障实例得到了验证。The operating mode of the engine and the composition of vent gas has the most direct connection. Through experiment this article summarized the relation between each engine partial technical conditions and the composition of vent gas, and analyzed the reason of the unusual composition of vent gas. Through the analysis of vent gas it can diagnose the position of engine fault, which was verified by the real fault example.
