奥迪五缸机电脑控制点火装置及其故障诊断

奥迪五缸机轿车采用的电脑集中控制式点火系统主要是通过各种传感器采集原始信号，经微处理器处理（如与微处理器内的ROM芯片中存贮的故障自诊断程序进行比较等），最终输出信号驱动执行部件，从而达到自动控制的目的。详细地介绍了该系统的工作原理和故障诊断方法。

The article presents in detail the working principle and trouble diagnostic method of a central control type ignition system by electronical computer adopted in the Audi car with five cylinder engine,which collects prime signals through various sensors,and then these-signals are processed by micro processor (for example, to compare signals with a self diagnosis program stored in ROM core plate of the micro processor etc.). Finally output signals passed to executive components to achieve the aim of self control.
