| 摘 要： | 在对发动机外特性曲线扭矩与转速实验数据分析的基础上，对原有的经验公式进行了分析、改进，提出了新的经验公式．由这一经验公式所计算的数值，在最大扭矩与最大功率点之间，可与实验数据拟合得很好．与原经验曲线相比，新经验曲线与实验曲线的离差可下降50％以上．

| Abstract: | Based on the Analysing of experimental data of wrench moment and turning speed of engine, a new form of the outer characteristic curve is proposed. The new form is good to fit the experimental data between the point of the maxmum wrench moment and the point of the maxmum power. The standered differince between the data computed by the the new form and the experiment data is about 50％ less than that between the data computed by the the old form and the experiment data. |
