数据流和波形诊断技术在发动机故障诊断中的应用

Application of Data Flow and Waveform Analysis Technology on Engine Fault Diagnosis

随着电控发动机的广泛应用,为发动机故障排查提供了很大的便利。通过故障码的读取,可以快速定位故障原因。但在一些特殊情况下,发动机无法报出故障码或者报出的故障码不准确时,需要分析相关数据流,并结合发动机外围件的信号波形,进行故障的排查和定位。

With the continuous development and application of electronic control engine,it provides great convenience for processing fault.It is quickly locate faults by reading fault codes.On special occasion,the engine cannot accurately report the fault,we need to analyze the data flow and combine the waveform of sensors and actuators,to achieve the rapid and accurate judgment of engine fault reasons.
