发动机相位关系信号测试研究

Engine signal phase relationship test research

发动机工作过程中影响发动机性能的因素有很多。其中,发动机的相位关系就是很重要的影响因素之一。它影响着发动机进气、喷油、点火角度,更决定了整个配气机构工作是否合理。发动机相位关系主要由曲轴、凸轮轴转速信号,缸压信号的关系所组成,这三个重要的相位关系信号之间对应关系正确与否将直接影响了发动机工作状态及性能的好坏。

Engine during engine performance factors, many of them, the phase relationship of the engine is a very importantfactor. It affects the intake, fuel injection, ignition angle determines the entire valve timing is reasonable. Phase relationshipmainly by the crankshaft speed signal, the speed signal and the relative relationship between camshaft cylinder pressuresignal is composed, the correctness of these three relatively phase signal relationship between the influence of the phaserelationship of the engine is reasonable, i.e., affect the engine performance is good or bad.
