摘    要
汽车作为现代社会人们出行的基本交通工具，汽车的科技发展水平也越来越迅速。汽车的电子技术水平在近几十年的发展过程中，有着越来越大的进步。汽车的点火系统做为普遍存在于以内燃机为动力源的车辆当中，点火系统的设计与布置对车辆的行驶有着极其密切的关系。点火系统是汽油发动机重要的组成部分，对发动机的性能有着决定性的影响。随着汽车工业的不断发展，汽车电子化程度不断提高，汽车的点火系统已由传统的蓄电池点火系统发展到国内外广泛采用的电子点火系统，电子点火系统又称为半导体点火系统或晶体管点火系统，越来越多的汽车厂家将电子技术应用到了汽车上.
本文主要设计一款汽车的点火系统，主要完成的内容有对汽车点火系统的方案论证、原理叙述、各部分的结构设计等。还包括点火系统的设计概念、点火系统的发展趋势、点火系统的原理及分析等。
本文希望通过汽车点火系统的设计，来使设计者掌握本专业的所学知识，可以将理论知识融合到实际零部件系统的设计当中，并熟练掌握系统设计的流程与步骤。 [资料来源：THINK58.com]

Abstract
As the basic means of transportation for people to travel in modern society, the scientific and technological development level of automobile is also more and more rapid. The level of automotive electronic technology has made greater and greater progress in the development process of recent decades. The design of ignition system is closely related to the driving power of vehicle. Ignition system is an important part of gasoline engine, which has a decisive impact on the performance of the engine. With the continuous development of automobile industry and the continuous improvement of automobile electronization, the automobile ignition system has developed from the traditional battery ignition system to the electronic ignition system widely used at home and abroad. The electronic ignition system is also known as semiconductor ignition system or transistor ignition system. More and more automobile manufacturers have applied electronic technology to automobiles
