例1 大修后发动机机油压力失常1 故障现象一台东风 EQ6100发动机,因捣缸事故曾在某汽车修理部大修过。大修后主要技术性能很好,但机油压力不正常。2 故障分析我们对该发动机进行检查。先用机械式机油压力表对该发动机的机油压力表和机油压力感应塞进行校对和检验,结果证明两者指示准确、工作可靠。接着对发动机各工况下的机油压力进行观察和记录:冷车时,怠速油压为
Example 1 overhaul the engine oil pressure failure 1 failure phenomenon A Dongfeng EQ6100 engine, due to the tanker accident overhaul in a car repair department. After major overhaul the main technical performance is good, but the oil pressure is not normal. 2 Failure Analysis We examined the engine. The first mechanical oil pressure gauge on the engine oil pressure gauge and oil pressure sensor plug proofing and inspection, the results show that both instructions accurate and reliable work. Then the engine oil pressure under various operating conditions were observed and recorded: cold car, idle hydraulic pressure is
