发动机掉功率、排温低及不能点火故障排查分析

Analysis Faults about Engine Dereasing Power Decreasing Exhaust Temp and Can not be Started

某柴油发动机在试验过程中出现了掉功率、排温低及不能点火等故障。为了排查问题,建立了针对发动机掉功率、排温低及不能点火的鱼骨图,并逐一排查问题。通过排查,最终找到了发动机失效的原因。

In the process of testing,a problem shows that the power of diesel engine has decreased and the temperature of exhaust gas at a lower and lower standard. At last the engine can not be started.For solving the faults,we built the fishbone diagram,and investigated all the possible reasons. Finally we find out the real reason.
