ABSTRACT:
The invention relates to a combustion air supply arrangement, including an air intake duct of an internal combustion engine, and a compressor arranged in the air intake duct, and a first throttle located downstream the compressor and upstream the internal combustion engine and arranged to change the flow area of the air intake duct between the compressor and the internal combustion engine, the same furthermore including a second throttle, which is located upstream the compressor and which is arranged to change the flow area of the air intake duct upstream the compressor. Furthermore, the compressor is a centrifugal compressor, the rotational speed of which is directly dependent on the rotational speed of the internal combustion engine, and that the combustion air supply arrangement is arranged in such a way that the sucked-in air is compressed once between the second throttle and the internal combustion engine.
