摘要
随着汽车技术的飞速发展和人们对安全、舒适、节油及环保要求的提高，电控发动机在汽车上的应用已经普及。作为汽车维修和检测人员，为适应现代汽车新技术发展的需要，必须主动去了解、认识电控发动机，为下一步的学习作好铺垫。
现代电子技术的快速发展，特别是微机技术在汽车上的广泛应用，使得汽车的内涵和功能不断拓展和延伸，汽车机电一体化和汽车电子化正逐渐成为现代汽车（特别是轿车）的基本特征。发动机电控作为汽车电控中的重要一环，为适应日趋严格的排放、安全法规，已受到国内外汽车厂商的高度重视，并得到了空前发展。
本篇论文将着重介绍电控发动机的基础理论知识和基本维修技能，它以最近生产的国产轿车及部分进口轿车电控发动机为例，简要地介绍了典型结构特点、故障诊断方法及其维修技术，并精选大量典型维修案例加以分析。要想成为一名出色的维修专家，就必须掌握电控发动机的基本结构组成及其工作原理，为维修打好扎实的理论基础。

Abstract
Starter for starting engines, is the key components of car. Hyundai motor starter for the requirement is: small volume, light weight, reliable performance, large power, long service life. So the structure design of the starter has once again the new breakthrough tradition, which led to the design of new technology, new material and new technology applications, Make the volume, weight, starter motor performance and life are achieved more satisfaction degree.
Starters must meet the future development of the new cars are endless varieties, with the optimization design of automotive starter to constantly improve the level of design and manufacture, puts forward a higher request. Automobile industry will in future in energy conservation and environmental protection. Also will constantly toward the reliable, safe, comfortable, etc. The key components of a car equipped with science and technology will be the high-speed development, new processing technology, automatic control technology, automatic detection technology and the wide application of computer technology, and constantly improve, still in the small, lightweight, high-power output, long life direction.
This article introduces various types of starter, the structure and the working principle of the common faults can explain and maintenance methods, we can understand more about the performance of different types of starter.
Keywords：the starter principle development structure
