摘　　要：建立了基于神经网络的发动机点火系统故障诊断专家系统 ,并较好地应用于自行开发的汽车示波器上。经实车测试证明 。Ignition system is the major composition of a gasoline engine and its working condition directly influences the performance of an engine. It is very important to test engine ignition and diagnose engine fault timely. Automobile oscilloscope is an effective instrument for examining engine ignition. It can determine the fault part of mechanical system, fuel system and ignition system of engine by displaying ignition wave. The fault diagnosis expert system of engine ignition based on neural network was established and applied for the mentioned self-made, automobile oscilloscope. The practical test on the CA488Q engine shows that the oscilloscope can accurately diagnose engine fault on line and the approach is successful.
