汽车发动机电子控制系统的故障诊断与维修

Fault Diagnosis and Repair of Automobile Engine Electronic Control System

随着科学技术的快速发展,我国汽车业逐渐实现电子化,作为汽车重要组成部分的发动机也进入电子控制化时代。本文主要分析发动机电子控制系统的工作原理,并探讨发动机电子系统的故障及诊断方法,最后以丰田卡罗拉GL1.6为例,分析发动机怠速转速过低的诊断及故障排除方法。

With the rapid development of science and technology, China＇s auto industry gradually realized electronically, as an important part of the car engine has entered the era of electronic control. This paper analyzes the working principle of electronic engine control systems, and to explore fault and diagnosis engine electronics system, and finally to the Toyota Corolla GL1.6 example, analysis of the engine idle speed is too low diagnostic and troubleshooting methods.
