文档介绍：汽车点火系统故障诊断与维修
摘要
汽车工业的快速发展必将带动维修行业的前进步伐。本文则主要通过对汽车点火系统分类及结构的检测与维修和常见故障诊断与维修的方法的论述,使人们对点火系有了更深入的了解,有助于维修技师对点火系统进行快速的诊断和维修,有助于维修行业的发展。随着科学技术的不断发展,汽车的技术也有了巨大的发展,大量地使用电子元件以及利用计算机监控汽车的运转。而汽车发动机的点火系也有了很大的变化:从传统点火系到电子点火系,再发展到无分电器的独立点火系统,而其中的无分电器的独立点火系统又分为DFS(双火花线圈)点火系统和EFS(单火花线圈)点火系统。这些点火系统有各自的特点和结构及组成元件。

Abstract
The rapid development of automobile industry is bound to lead to repair the pace of the industry. This article is mainly based on the classification and structure of automobile ignition system testing and repair mon fault diagnosis and repair of the methods are discussed, so that people on the ignition system with more understanding, contribute to the repair technician to the ignition system for rapid diagnosis and repair, helps to repair the development of the industry. With the development of science and technology, automotive technology has achieved great development, to use a large number of ponents and the use puter monitoring vehicle operation. Automobile engine ignition system also had the very big change: from the traditional ignition system to the electronic ignition, and then to the distributor less ignition system of independent, of which the distributor less ignition system is divided into independent DFS ( double spark ignition system coil ) and EFS ( single coil ignition system. ). The ignition system has its own characteristics and structure ponents.

第1章绪论
一百多年来伴随着汽车的发展,汽油发动机的点火技术也逐渐提高。1886年,第一辆以四循环内燃机为动力的汽车使用的是磁电机点火系统
