Method for operating internal combustion engine in motor vehicle, involves driving first compressor by turbine, closing second valve element, and partly opening first valve element in operation range

摘要

The method involves arranging downstreams of a branching point (18) and a first compressor (36) and upstream of a supply point (20) in an air conduit (16). Through-flow of a cross-section of the conduit is adjusted by a first valve element (42). Air is compressed by the first compressor (26) while driving a second compressor and compacting the air caused by the second compressor in an operation range of an internal combustion engine (10). The first compressor is driven by a turbine (24). A second valve element (40) is closed, and the first valve element is partly opened in the range.
