发动机凸轮轴、曲轴信号不同步故障问题研究

Study on Signal Fault of Engine Camshaft

发动机凸轮轴、曲轴转速传感器信号发生错误,会导致发动机动力性和经济性变差,严重时甚至会导致发动机不能起车。本文针对信号问题开展研究,全面分析造成信号不同步问题的原因,总结查核信号问题的方法,对于指导发动机的设计及故障的排查具有重大意义。

Engine camshaft and crankshaft speed sensor signal an error occurs,will cause the engine performance and fuel economy,serious when even lead to engine can't a car.Signal problems,the author of this paper research,comprehensive analysis of the cause of problem of signals are not synchronized,summarizes check signal problem,for guiding the design of the engine and the fault is of great significance.
