汽车发动机失火故障的诊断方法研究

失火是发动机常见故障之一。失火的原因有很多。油路、电路和机械零件中的故障可能导致发动机失火。发动机失火故障发生后,不仅降低了发动机工作的稳定性、动力性和经济性,而且会增加因燃油燃烧不完全或不燃烧而产生的排放污染。因此,有必要对汽车发动机失火故障诊断方法进行研究。

Research on Diagnosis Method of Automobile Engine Misfire

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.
