摘 要：失火是發(fā)動(dòng)機(jī)常見故障之一。失火的原因有很多。油路、電路和機(jī)械零件中的故障可能導(dǎo)致發(fā)動(dòng)機(jī)失火。發(fā)動(dòng)機(jī)失火故障發(fā)生后，不僅降低了發(fā)動(dòng)機(jī)工作的穩(wěn)定性、動(dòng)力性和經(jīng)濟(jì)性，而且會(huì)增加因燃油燃燒不完全或不燃燒而產(chǎn)生的排放污染。因此，有必要對(duì)汽車發(fā)動(dòng)機(jī)失火故障診斷方法進(jìn)行研究。

Abstract：Misfire is one of the common engine failures. There are many reasons for the fire. Failures in the oil circuit， electrical circuits， and mechanical parts may cause the engine to catch fire. After an engine misfire failure occurs， it not only reduces the stability， power and economy of the engine， but also increases the emission pollution caused by incomplete or incombustible fuel combustion. Therefore， it is necessary to study the method of car engine misfire fault diagnosis.

Key words：car maintenance， engine， fault diagnosis
