| 摘 要： | 通过分析发动机实测试验数据,提出了燃油消耗率同转速和扭矩之间存在类似幂指函数的关系,运用多元回归的方法对发动机的万有特性曲面进行了拟合,对拟合结果用数理统计的方法进行了检验,最后指出对发动机万有特性曲面的拟合采用分段函数进行数值计算,将得到更为精确的结果。

| Abstract: | According to the datum of engine experimenting, this article puts forward the non-linearity relationship between fuel consumption rate and rotate speed and torque. The universal characteristic of engine is cambered by using the multiple regression analysis. The result of calculation is checked out with statistic inspection. This article, in the end, points out that the universal characteristic of engine will be more accurately expressed by subsection function. |
