給機付き内燃機関の吸気制御装置。 An intercooler for cooling the air compressed by the supercharger is installed in a portion between the supercharger and the throttle valve of the intake passage leading from the supercharger to the internal combustion engine via a throttle valve for adjusting air amount. and a bypass passage that detours around the intercooler, at a portion where the intake passage from the supercharger branches into a passage to the intercooler and a bypass passage,
In an intake system comprising a pressure-operated switching valve for selectively switching an intake passage from a supercharger to either a passage to an intercooler or a bypass passage, a pressure chamber in the switching valve includes: The intake pressure on the downstream side of the throttle valve is introduced and connected so that when the intake pressure becomes lower than a certain set value, the switching valve operates to cut off a passage from the supercharger to the intercooler. Air intake control device for internal combustion engine with supercharger.
