Study on the Fault Diagnosis Expert System of Engine Ignition

Ignition system is the major part of gasoline engine, its working condition directly affects the engine performance. It is very important to measure engine ignition and diagnose engine fault timely. Automobile oscilloscope is an effective instrument 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 is established and applied for the mentioned self-made automobile oscilloscope .The road test results on the CA488 engine show that the oscilloscope can accurately diagnose engine fault on line and the approach is successful.;
