Fan clutch device for engine and engine with same

The invention discloses a fan clutch device for an engine and the engine with the fan clutch device. The fan clutch device for the engine comprises a shell, a partition plate, a driving plate, a rotating shaft and a control assembly. The partition plate is arranged in a cavity and partitions the cavity into an oil storage cavity and a working cavity, and a switch for controlling the circulation of the amount of oil in the oil storage cavity and the working cavity is arranged on the partition plate. The rotating shaft is connected with the driving plate and drives the driving plate to rotate. The control assembly controls the switch to being opened and closed, and after oil in the oil storage cavity enters the working cavity, the shell is driven by the rotating plate to rotate. According to the fan clutch device for the engine, the rotating speed of the shell relative to the rotation shaft can be controlled, the variable speed control over the rotating speed of a driven object can be achieved, energy consumption of a cooling fan and the like can be greatly reduced, and accurate heat management can be conducted on the engine.
