特徴とする過給機付き内燃機関。 The turbocharger has a leak passage that opens to the atmosphere from the intake passage downstream of the turbocharger and upstream of the carburetor, and this leak passage is equipped with a control valve that closes and opens according to increases and decreases in engine load. In an internal combustion engine, a circulation passage is provided that communicates a leak passage downstream of the control valve with an upstream side of the supercharger, and a leak passage is provided in the leak passage or the circulation passage when the temperature of intake air or the like is low. closes and opens the circulation passage, while opening the leakage passage when the temperature is high.
An internal combustion engine with a supercharger characterized by being provided with a switching valve that closes a circulation passage.
