微机控制点火系工作原理及故障诊断与排除

Working Principle and Trouble shooting of the Computer Controlled Igniton System

详细介绍微机控制点火系的组成、工作原理及故障处理。由于没有任何运动摩擦机件，这种点火系具有如下优点：提高了工作可靠性，减少了无线电干扰，自动修正点火正时，提高了发动机的动力性、燃油经济性，降低了排气污染。按结构的不同，可分为有分电器微机控制点火系和无分电器微机控制点火系两类。

This paper introduces in detail the component structure, the working principle and the trouble shooting of the computer controlled ignition system. Having no friction part, it has the following advantages: the improvement of working reliability, the reducing of radio interference, self adjusting the ignition timing, the improvement of the engine power and fuel economy and the reducing of pollution. According to the structure, these systems can be divided into two groups with distributor and distributorless.
