The first cylinder group is connected to the second surge tank via a first surge tank. A shut-off valve is arranged in the connecting portion of the first surge tank and the second surge tank. When the level of the load of the engine becomes higher than a predetermined level, the shut-off valve is slowly opened by a DC motor.
