分析表明,随着柴油牌号的降低,CI计1与CI(?)1的平均差值在增大;CI计1与CI(?)1的最大差值、最小差值、平均差值小于或等于CI计2与CI(?)2的对应值,最小差值的平均值增大;CI计1计算法的最大值个数与CI(?)2计算法的最小值个数有减少趋势,CI计1计算法的最小值个数与CI计2计算法的最大值个数有增加的趋势;用CI计2计算法计算所得柴油十六烷指数平均值为最大、多数CI(?)2为最小。
The analysis shows that with the decrease of diesel grades, the average difference between CI 1 and CI (?) 1 increases; the difference between CI 1 and CI (?) 1 is less than or equal to Equal to the corresponding value of CI 2 and CI (?) 2, the average value of the minimum difference increases; the maximum number of CI 1 calculation method and the minimum number of CI (?) 2 calculation method decrease, The minimum number of CI-1 method and the maximum number of CI-2 method tend to increase. The average of Cetane Index of Diesel Oil calculated by CI-2 method is the largest, most CI (?) 2 For the smallest.
