本文介绍一种新研制的微机控制点火系统的构成和工作原理。此系统以发动机转速、进气管压力和冷却水温等作为输入参数,采用静态存贮器控制方法,控制点火提前角和闭合率。与传统的点火系统相比较,此系统具有点火稳定和均匀等优点。通过试验证明,使用这种系统可以降低发动机循环变动量,改善各缸工作的均匀性,从而使发动机的动力性和经济性得到改善。 This article describes a newly developed microcomputer control ignition system composition and working principle. The system takes engine speed, intake manifold pressure and cooling water temperature as input parameters, and adopts static memory control method to control ignition advance angle and closing rate. Compared with the traditional ignition system, this system has the advantages of stable and uniform ignition. Experiments show that using this system can reduce the engine cycle variation, improve the uniformity of each cylinder work, so that the engine power and economy improved.
