摘　　要：发动机怠速抖动不仅影响发动机的性能,而且对发动机的寿命也有不小的影响。如何解决汽车怠速时发生抖动这一问题,成为很多维修厂和企业亟需解决的难题。文章旨在通过分析发动机怠速时容易发生抖动问题的原因,并提出解决发动机怠速时发生抖动问题的方法。文章通过实例分析法,最终得出结论:发动机怠速抖动主要原因是进气系统故障、燃油系统故障、点火系统故障,并提出发动机怠速抖动的诊断与排除方法。Engine idle shake not only affect the engine performance,but also to the life of the engine has a big influence how to solve the jitter occurred this problem,when the car idle for many repair shops and companies need to solve the problem of this article is to through the analysis of the engine idle speed are prone to the cause of the jitter problem,and puts forward the method to solve the problem of engine idle when shaking through example analysis,this paper finally concluded that the engine idle dithering main reason was that the air intake system failure fuel system failure ignition system failure,and puts forward the diagnosis and elimination method of engine idle speed jitter.
