Abstract
Abstract The invention concerns a charged internal combustion engine with at least one stage of charging by a turbocharger. The invention is characterized by the fact that at least one supplemental compressor is connected parallel to or in series with the turbocharger, where the supplemental compressor has a drive independent form the working medium cycle of the internal combustion engine.
