| Abstract: | Ignition waveform reflects the relationship between the variation of primary,secondary electrical current and voltage of ignition coil and the time or crankshaft turn angle of engine during operation of the engine ignition system,which is displayed on a single purpose oscilloscope and can show working mode of the ignition system in real time.Secondary ignition waveform analysis is a common method of fault diagnosis of modern vehicles.In this article,the author analyzes the standard waveforms and fault waveform of ignition system and uses a typical fault waveform case to illustrate how to use the secondary ignition waveform for automobile fault diagnosis. |
