【摘要】 论述了系统的硬件组成与工作原理,指出了基于频谱分析的软件算法及用户界面的实现。通过频谱分析对各个气缸的点火电压信号进行检测,得到了出现故障气缸的点火电压信号波形的峰值最小,并以此来鉴别故障气缸。更多还原

【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.更多还原
