関の吸気制御装置。 An engine-driven mechanical supercharger is placed in the intake passage upstream of the throttle valve, and an intake cutoff valve is placed in the intake passage upstream of the mechanical supercharger. A bypass passage is branched from the passage, the bypass passage is connected to an intake passage between the mechanical supercharger and the throttle valve, a bypass control valve is provided in the bypass passage, and the bypass control valve is opened during deceleration operation. In an internal combustion engine in which the intake cutoff valve is closed, the air circulation area of the intake cutoff valve when the intake cutoff valve is closed is larger than the air circulation area of the intake cutoff valve when the throttle valve is at its idling opening. An enlarged intake control device for an internal combustion engine.
