摘　　要：文章针对发动机排气冒烟故障诊断进行了归纳和研究。首先对排气异常冒烟的几种现象进行了详细的描述,主要包括冒蓝烟、冒黑烟和冒白烟等。然后分析了发动机各个系统可能导致排气异常的失效模式。最后通过实际案例说明了利用排气烟雾快速判断发动机故障思路的可行性,排气烟雾的颜色特征可用于发动机故障的诊断。In this paper,the fault diagnosis of engine exhaust smoke is summarized and studied.Firstly,several phenomena of abnormal exhaust smoke are described in detail,including blue smoke,black smoke and white smoke.Then the failure modes of each engine system that may lead to abnormal exhaust gas are analyzed.Finally,the feasibility of using exhaust fumes to quickly judge engine faults is illustrated by a practical case.The color characteristics of exhaust fumes can be used to diagnose engine faults.
