設けたことを特徴とする内燃機関の吸気装置。An intake passage that communicates the outside of the internal combustion engine with the combustion chamber and allows air taken in from the outside to flow toward the combustion chamber, a throttle valve provided in the middle of the intake passage that can freely open and close the intake passage, and a throttle for the intake passage. It is equipped with a regulator passage that communicates between the upstream side and the downstream side of the valve, and an air regulator that is installed in the middle of this regulator passage and can change the flow area of the regulator passage. In the intake system for an internal combustion engine, the air regulator expands the flow area of the regulator passage, and as the cooling water temperature increases, the air regulator gradually reduces the flow area of the regulator passage. An internal combustion engine characterized in that a flow passage area variable means is additionally provided in the middle of the regulator passage so that the flow passage area of the regulator passage can be immediately reduced to a predetermined value when the temperature of the cooling water exceeds a predetermined value. intake device.
