Abstract

A method for operating a drive device includes heating a hot air stream with a heating device integrated in a cylinder head of an internal combustion engine of the drive device, wherein the internal combustion engine is connected with an exhaust gas system; mixing the hot air stream upstream of a catalytic converter with a cold fresh air stream for adjusting a defined temperature of the hot air stream; and supplying the hot air stream having the adjusted defined temperature to the catalytic converter in at least one operating state of the internal combustion engine so as to heat the catalytic converter.
