Methods and systems are provided for a boosted internal combustion engine. In one example, 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 of the 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 width of 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 via the compressed air line.

Embodiments for cooling a turbine of an engine are provided. In one example embodiment, an internal combustion engine comprises a turbocharger including a turbine having a coolant jacket integrated in a housing of the turbine, and an oil circuit coupled to the coolant jacket of the turbine. By cooling the turbine with the oil circuit, the turbine may be constructed from less-heat resistant materials.
