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

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 electronic components

and the use of computer 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 and

components.
