能使发动机顺利起动所必需的曲轴转速，称为起动转速。
起动转速取决于发动机的型号、大小和状态以及进入发动机的空气的温度。
The starting speed depends upon the type and size of the engine, its condition and the temperature of the air entering the engine.
研究了环境温度，过量空气系数，蓄电池电压，点火提前角对单循环冷起动时，起动转速和排放的影响。
The effects of environment temperature, excess air ratio, storage battery voltage on start speed and emissions are studied.
在发动机台架上对微型涡喷发动机进行的起动过程控制和转速闭环调节试验表明，该控制软件在时间精度和可靠性方面能够满足发动机控制的要求。
Engine tests of starting procedure control and rotation speed in closed loop have proven that the time precision and reliability of this software meet the demands of engine control system well.
