燃機関の吸気装置。 An intake system for an internal combustion engine, comprising: an intake control valve that generates an intake swirl by closing an intake passage; and a drive control means that closes the intake control valve when the air-fuel ratio exceeds a predetermined value. The present invention is characterized by being provided with a determining means for determining when to increase and when to decrease the opening of the control valve, and a predetermined value changing means for setting the predetermined value to a different value when increasing and decreasing the opening. Intake system for internal combustion engines.
