摘要 简单阐述火花塞离子电流法的基本原理,以NF157FMI汽油发动机为例设计一套火花塞离子电流检测系统.基于气缸内燃烧时产生的离子电流信号,经小波阈值去噪后分析其波形特点,根据其获得的燃烧信息实现对发动机早燃状态的检测. 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.
