| Abstract: | The basic principle of the spark plug ion current method was elaborated simply. Taken the NF157FMI gasoline engine as an example, a set of spark plug ion current detection system was designed. Based on the ion current signal produced by the combustion in the cylinder and the wavelet threshold denoising used to analysis the waveform characteristics, the combustion information was obtained for the preignition state detection of engine. |
