介绍了作者开发的柴油机工况监测诊断系统．提出了一种基于数字信号理论的数字滤波法，采用该方法处理内燃机示功图，可以消除通道效应对系统测量精度的影响；并在分析内燃机燃绕特性的基础上，给出了一种校正测量上止点的方法
This paper introduces the diesel condition monitoring and diagnosis system developed by the author. A digital filter method based on digital signal theory is proposed. By using this method to process the engine dynamometer, the influence of the channel effect on the system measurement accuracy can be eliminated. Based on the analysis of the combustion characteristics of the internal combustion engine, a correction method Method to measure TDC
