A new method to determine mechanical efficiency of diesel engine by acceleration decelerationmethod under non external load is proposed.
提出了一种快速确定柴油机机械效率的方法——无外载加减速法。

Conventional acceleration and deceleration control method plans velocity in single segment of machining path, so it can not meet the need for high speed.
传统的段内加减速控制方法由于整体速度偏低，不能适应高速加工的需要。
