When the clutch is in the coupling (or normal running) position, power flows through it from the engine to the transmission.
当离合器处于结合状态时(或者说处于正常运行状态时)，动力从发动机传递到变速器。

This special viscous clutch is much like the viscous coupling sometimes found in all-wheel drive cars.
这种特殊的粘液离合器就像四轮驱动汽车里的粘性联轴器。

It is very hard to solve well the start control problem of the clutchcoupling by relying on the traditional control method and the auto-control method based on the modern control theory.
