摘要
通过对柴油机气缸压力测量中的通道误差的分析研究,基于MATLAB工具箱设计了一种低通滤波器对示功图进行处理,计算结果表明该方法简单易行,可以有效消除通道误差,满足计算精度。
In this paper, the passage error in diesel engine cylinder pressure measurement is studied. A low pass filter to deal with the diesel engine indicator diagram is designed according to the MATLAB tool box. The calculated results have proved that the method can eliminate the errors of passage effectively, and satisfy the calculating accuracy.
