PURPOSE:To enable a device to surely reduce a vibration in an engine, by increasing the engaging speed of a subflywheel when the engine is driven in operation with large air-fuel ratio. CONSTITUTION:When an engine is driven in operation with large air-fuel ratio easily generating a vibration, a subflywheel 7 sets its engaging speed NS to a large value. Consequently, the engaging speed, when it is set to 1,200rpm at operation time of the engine in its small air-fuel ratio, is increased to as large as 1,500rpm when the engine is in operation with large air-fuel ratio. Accordingly, the engine, adequately meeting a difference of the air-fuel ratio, comes to effectively reduce a vibration of the engine 1. |
