When the locomotive is traveling at a constant speed or idling, the battery rather than the diesel engine can power the motor.
当火车头在相对恒定速度下前进或者空转时，这时电池就为马达提供能量，柴油发动机不工作。

If the light ahead is red, the driver is told the optimal speed to avoid stopping and idling.
如果前面的交通灯是红的，就会告诉司机一个最佳车速以避免停车和挂空挡。

By taking account of nonlinearity, time variation and unsteadiness of idling process in engines, this paper studies the application of fuzzy control theory in the idlingspeed control.
