The invention relates to systems and methods for a boosted internal combustion engine with an intake-side bypass line. Methods and systems are provided for a boosted internal combustion engine. In oneexample, a system may include an intake system for supplying charge air, a compressor arranged in the intake system, a first shut-off element arranged in the intake system upstream of an impeller ofthe compressor, a bypass line that branches off from the intake system upstream of the first shut-off element and that rejoins the intake system upstream of the impeller, a second shut-off element arranged in the bypass line, a compressed air line that opens into the bypass line downstream of the second shut-off element, and a third shut-off element arranged in the compressed air line. A map widthof the compressor may be increased by providing airflow to the impeller via the bypass line during low mass flow conditions, and impeller acceleration may be expedited by providing compressed air viathe compressed air line. 本发
