【Abstract】 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.更多还原
