浅谈汽油发动机气缸压力检测

Cylinder pressure detection of gasoline engine

随着经济社会发展,中国已经成为汽车上的国家,汽车成为人们生活中重要的交通工具。发动机是汽车的动力来源,发动机机械性能中的气缸压力是发动机的一个重要参数,对发动机性能影响极大。如果气缸压力过低,会导致发动机燃烧不完全,降低燃油经济性,引发汽车启动困难,怠速不稳,行驶无力等一系列连锁故障。文章主要讲述气缸压力检测步骤,气缸压力检测标准值,气缸压力检测结果分析及案例分析。

With the development of economy and society,China has become a country on automobiles and an important means of transportation in people's lives.Engine is the power source of automobile.Cylinder pressure in engine mechanical performance is an important parameter of engine,which has great influence on engine performance.If the cylinder pressure is too low,it will lead to incomplete combustion of the engine,reduce fuel economy,cause a series of interlocking failures such as difficult start-up,unstable idle speed,powerless driving and so on.This article mainly describes the cylinder pressure testing steps,cylinder pressure testing standard values,cylinder pressure testing results analysis and case analysis.
