本文提出了用低压示功图按照拉格朗日多项式所确立的方法,计算在任何工况下各类发动机的充气效率。文中画出柴油机和汽油机的实测法和计算法之间充气效率的对比曲线,并描述出满意的结果。
In this paper, we propose to calculate the charge efficiency of all kinds of engines under any operating conditions by using the low-voltage dynamometer in accordance with the Lagrange polynomial method. The paper draws a contrast curve of the inflation efficiency between the measured and calculated diesel and gasoline engines, and describes the satisfactory results.
