徴とする過給機付内燃機関の吸気装置。 A plurality of resonance-type intake pipes connected to the upstream side of the intake collector and having a shape and dimensions suitable for inertial supercharging, and a control valve that communicates or shuts off the resonance-type intake pipes within the intake collector. In the intake system for a supercharged internal combustion engine, the control valve is opened in an operating range where the resonance type intake pipe is in a resonance region and the base supercharging pressure of the supercharger is high;
On the other hand, an intake system for a supercharged internal combustion engine, comprising a control means for closing a control valve in an operating range where the base supercharging pressure is low and in a resonance region.
