摘要
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。
On the basis of both IMEP and mass fraction burned derived from continuous cyclic pressure diagram, the correlation of vaiation coefficients of IMEP versus engine speed, load, A/F ratio and spark timing are determined. Analyse the autocorelation coefficients among the crank travelling angles from spark timing to mass fraction burned equal to 0.1, 0.5 and 0.9 respectively. The autocorelation coefficients between IMEP and crank traveling angle from spark timing to mass fraction burned equal to 0.1, 0.5 and 0.9 respectively are also studied.
