| Abstract: | The hardware components and their working principle of the system were discussed. The software algorithm of spectrum analysis and user interface were achieved. Through spectrum analysis of the ignition voltage signal detection of each cylinder, the minimum peak of ignition voltage signal waveform of fault cylinder was found, with which fault cylinder was taken to be discriminated. |
