摘要
利用实测示功图对柴油机燃烧过程进行分析,是进行柴油机性能研究的重要手段。针对这一需要,对实测示功图中压力值的修正处理方法进行了研究,并利用MATLAB工具箱对测量信号进行频谱分析,就通道效应对示功图的影响进行了讨论。
It＇s an important mean to predict the performance of diesel engine through the study of combustion process based on the measured indicator diagram correctly.So in this paper,the methods of modifying the pressure of indicator diagram is studied,and the frequency-chart of the measured signal are analyzed depending on the MATLAB tool-box,and influence of passage effect for indicator diagram is analyzed.
