通过对柴油机燃油压力波形的分析与研究，探讨了波形形成的机理以及波形局部畸变与燃油供油系统故障之间的联系。介绍了燃油压力波形的特点及数据特征，为利用燃油压力波形诊断燃油系统故障提供了必要的数据处理依据。
By analyzing and studying the pressure waveform of diesel fuel, the mechanism of waveform formation and the relationship between local waveform distortion and fuel supply system failure are discussed. The characteristics and data characteristics of the fuel pressure waveform are introduced, which provides the necessary data processing basis for diagnosing the fuel system fault using the fuel pressure waveform.
