作者由连续循环的压力示功图求出各循环的平均指示压力及燃烧百分率,取得了平均指示压力变动率随转速、负荷、空燃比、点火提前角的变化曲线。并分析了从火花跳火到燃烧百分率为0.1、0.5、0.9时曲轴所转过角度之间的自相关系数。最后还研究了平均指示压力同从点火到燃烧百分率为0.1、0.5、0.9时曲轴转过角度之间的自相关系数。
The author obtained the average indicated pressure and the percentage of combustion of each cycle from the pressure cycle chart of continuous cycle, and obtained the curves of the average indicated pressure rate of change with the speed, load, air-fuel ratio and ignition advance angle. The autocorrelation coefficient between crankshaft rotation angle from spark-ignition to combustion percentage of 0.1, 0.5, 0.9 was analyzed. Finally, the autocorrelation coefficient between the average indicated pressure and the angle of crankshaft rotation from ignition to the combustion percentage of 0.1, 0.5, and 0.9 was also studied.
