摘要
本文研究了柴油机示功图测任通道的频域特征，以及通道几何尺寸、发动机工况与通道效应的关系．研究表明，用数字滤波法消除通道效应对提高示功图测量精度是行之有效的．
This paper has investigated the frequency band characteristic of pressuremeasuring passage for diesel engine indicator diagram determinat ion as well as therelationship of passage effect with passage geometry and engine operatingcondition. The investigation has shown that it can he effective to improve theaccuracy rate of indicator diagram determination by using digital filtration toeliminate the passage effect.
