御装置。 In an engine output control device that controls engine output using the intake inertia effect, three intake passages of different lengths, long, medium, and short, are connected in parallel to the engine intake section and are combined in parallel. The intake system is located upstream from the confluence of the long and short intake passages in this intake system, and is provided at the confluence branch of the medium and short intake passages. one intake control valve that can be opened and closed to open and close an intake passage with a length of Operate the above intake control valve to the state,
When the engine is in a medium speed range, the intake control valve is operated to open a medium length intake passage and close a short length intake passage; and control means for controlling an actuator that operates the intake control valve to a state where each of the short-length intake passages is cut off.
