Beschreibung
Zusammenfassung:	In a two-stage concept for supercharging of internal combustion engines, in which the first stage is performed by an exhaust-gas turbocharger and the second stage by an electrically driven compressor, the compressor is also used to provide the secondary air used for the heating of a catalytic converter. In this manner, the catalytic converter quickly reaches an efficient operating temperature.
