摘　　要：本文从点火不良、喷油不良、气缸气密性、进排气系统故障四个方面列举了可能引起发动机动力不足的故障原因,提出了发动机动力不足故障的“二分法”诊断思路,简化了故障诊断过程,并从存在“缺缸”故障与不存在“缺缸”故障两个角度阐述故障诊断方法,为同行提供参考借鉴。This article lists the possible causes of engine power shortage from four aspects:poor ignition,poor fuel injection,cylinder air-tightness,and intake and exhaust system failures,and proposes a"dichotomous"diagnosis method for engine power shortage failures to simplify the fault diagnosis process,and the fault diagnosis methods are explained from the two perspectives of"cylinder shortage"and non-existence of"cylinder shortage"faults,so as to provide reference for people.
