氧传感器波形分析法在电控发动机故障诊断中的应用

Application of Waveform Analysis of Oxygen Sensor to Fault Diagnosis of Electronic Engines

文章就如何将氧传感器的波形分析运用于发动机的故障诊断进行探讨分析,确定氧传感器自身状态正常的方法,指出了电控发动机正常工作时氧传感器的波形要求,归纳了杂波的类型。在此基础上,对几种故障下氧传感器的波形进行了分析,为汽车发电机的维护提供了具有较强参考意义的故障诊断手段。

Automobile electronic control technology makes fault-diagnosing increasingly rely on fault codes,data flow,waveform analysis and some other means.Luckily,the waveform analysis of electronic signals can greatly make up for the lack of fault codes and data flow,so it has been given much attention nowadays.The paper analyzes how to apply the waveform analysis of oxygen sensor to the engine fault diagnosing.
