| 摘 要： | 通过优化火花塞离子流检测电路,抑制了点火高压所产生的高频高压干扰,得到了幅度在0.3～3.2V量级的稳定离子流信号。分别更换了3种不同的火花塞,在发动机不同转速、不同负荷情况下采集离子流信号,对这些信号的幅度进行分析对比。经对比发现,离子流信号幅度受火花塞参数影响较为明显,并且基本上随转速、负荷的增加而增强。最后,分析了离子流信号幅度受火花塞参数、发动机转速和负荷等因素影响的原因。

| Abstract: | By optimizing the detecting circuit of spark plug ion-current,the high frequency and high voltage interference generated by the high ignition was successfully controlled and the stable ion-current signals within the range of 0.3~3.2 V were obtained.In the testing process,three kinds of spark plugs were used and their ion-current signals at different engine operating condition(different engine speeds and loads) were gathered.By comparing these three different signals,it is obvious that the ion-current amplit... |
