汽车发动机的故障诊断探究

Research on Fault Diagnosis of Automobile Engine

发动机内部构造和机械原理较为复杂,且长期在高温或高寒条件下运行,经常会造成机体内部的各种零部件性能发生变化,从而致使出现各类的运行故障。以发动机的构造和运行原理为基础,归纳出造成发动机故障的一些基本原因和主要类型,以期为解决发动机故障问题提供一定的参考。

The structure of automobile engine is complex. It works in high temperature or extremely cold conditions for long time,which makes the performances of automobile engine parts easy to change,and ultimately leads to engine failures. Based on structure and working principle of automobile engine,the common fault types and main fault reasons were summarized to provide reference for fault diagnosis of automobile engine.
