Beschreibung
Zusammenfassung:	A device for the aftertreatment of exhaust gases from an exhaust-gas source, having a spatially delimited flow path through which flow may pass proceeding from the exhaust-gas source, having a heating catalytic converter which is arranged in the flow path and which, as viewed in a flow direction, firstly has a catalytically active catalytic converter through which flow may pass and, following this in the flow direction, has an electrically heatable heating disk, wherein at least one outlet of a secondary air supply is arranged in the region of the heating catalytic converter such that a gas flow referred to as secondary air is fed into the flow path in the region of the heating catalytic converter.
