用Kaiser差分滤波方法识别柴油机燃烧始点的分析研究

Study on Identification of Combustion Timing of Diesel Engine with Kaiser Differentiator

柴油发动机燃烧时刻的辨识对于控制柴油机性能、故障诊断是一个重要的环节。文章在大量实验的基础上 ,提出并运用Kaiser差分算法 ,根据实测气缸压力识别柴油机的燃烧始点。同时 ,给出文献 [1 ]的修改算法。实践证明 ,运用Kaiser差分算法的有效性。

The identification of combustion timing of diesel engine is an important role on control of diesel engine characteristic and fault diagnosis.Based on experiments,this paper designs and uses a Kaiser differentiator to identify combustion timing according to cylinder pressure.It is proved that the method is valid.
