通过ZB 2型柴油机燃油喷射系统故障诊断仪 (即柴油机燃油压力波检测仪 )对DF4 型机车柴油机燃油压力波的检测 ,在对大量检测事例进行跟踪、统计、分析的基础上 ,揭示出燃油压力波的检测波形与该缸喷射装置质量状态的对应关系 ,并据此确定故障部位 ,为故障处理提供参考。
Through the ZB 2 diesel engine fuel injection system fault diagnosis instrument (ie, diesel fuel pressure wave detector) on the DF4 locomotive diesel fuel pressure wave detection, a large number of detection cases were tracked, statistical analysis, based on the revealed fuel pressure Wave detection waveform and the cylinder jet device quality status of the corresponding relationship, and to determine the fault location, provide a reference for troubleshooting.
