過給機付内燃機関の吸気装置。 In an intake system for an internal combustion engine with an exhaust turbo supercharger in which a throttle valve is installed in the intake passage, the intake passage leading to some cylinders is divided into a passage that communicates directly with the atmosphere and a passage that passes through the compressor of the exhaust turbo supercharger. In addition, a load detecting means for detecting the engine load and a passage switching means for selectively opening the two passages according to the engine load are provided. An intake system for an internal combustion engine with an exhaust turbo supercharger.
