機付エンジンの吸気装置。A supercharger, a cooler, and an on-off valve that opens and closes intermittently are arranged in the supercharging air passage in this order from the upstream side, and the supercharging air passage between the supercharger and the cooler opens and closes through the bypass passage. A control valve that communicates with the supercharging air passage on the downstream side of the valve, and also allows supercharging air to pass through the supercharging air passage when the engine speed is at medium or low speeds below the set value, and through the bypass passage when the engine speed is at high speeds exceeding the set value. An intake system for a supercharged engine, characterized in that it is provided with.
