摘　　要：在汽车故障诊断维修过程中单靠解码仪检测远远不够,波形分析法的运用可以提高故障诊断的效率。文章介绍了波形分析法的概念与优点以及波形分析法诊断故障的机理,并以氧传感器和喷油器为例试述波形分析法在汽车故障诊断中的具体运用方法。In the process of the automobile fault diagnosis, it is not enough to apply decoding instrument only, so application of waveform analysis method can greatly increase the efficiency of fault diagnosis. This paper first introduces the concept of waveform analysis, its advantages and its mechanism of diagnosing fault, and then describes the application of waveform analysis in automobile fault diagnosis by taking oxygen sensor and fuel injector as examples.

关 键 词：波形分析 故障诊断 氧传感器 喷油器
