開口させたことを特徴とする過給機付エンジン。 A main turbocharger, a sub-turbocharger, and an intake switching valve and an exhaust switching valve respectively provided in the intake and exhaust systems of an engine connected to the sub-turbocharger, and the sub-turbocharger performs a run-up operation on the sub-turbocharger before the sub-turbocharger reaches supercharging operation. The supercharged engine is configured to rotate and allow intake air to flow into the compressor inlet side of a main turbocharger through a compressor of an auxiliary turbocharger and an intake bypass passage that can communicate with the compressor, the engine having a supercharger that causes intake air to flow into the compressor inlet side of a main turbocharger through a compressor of a sub-turbocharger and an intake bypass passage that can communicate with the compressor. A supercharged engine characterized in that an end thereof is opened on the small-diameter wall side of a curved part of an intake passage located upstream of a compressor of a main turbocharger.
