Abstract: A method for operating an internal combustion engine is provided, wherein the internal combustion engine has at least one combustion engine and a fresh gas line and wherein a compressor, to which a trim adjuster is assigned, is integrated into the fresh gas line, said trim adjuster by which an edge section of the inlet cross section of a compressor wheel can be covered to a variable extent. In this case, the edge section of the inlet cross section is covered relatively little in a release position of the trim adjuster and covered relatively greatly in a covering position of the trim adjuster. It is provided that the trim adjuster is adjusted between the release position and the covering position, when substantially the same compressor pressure ratio and substantially the same fresh gas mass flow and substantially the same compressor efficiency are achieved in both operating positions.

Abstract: A method of operating a motor vehicle having an internal combustion engine, wherein the internal combustion engine has at least one combustion engine which is connected by a rotary drive via a transmission and optionally a clutch with powered wheels of the motor vehicle, and further comprises a fresh gas line, and wherein in the fresh gas line, a compressor is integrated, which is associated with a trim controller, by means of which an edge-side portion of the inlet cross section of a compressor impeller of the compressor is coverable to a variable extent. In this case, in a release position of the trim controller, the edge-side portion of the inlet cross section is covered relatively little, preferably the least possible, and in a covering position of the trim controller, is mostly covered, preferably as much as possible.
