Drive Device, In Particular For A Vehicle

A drive device for a vehicle with and an exhaust gas tract connected to engine. The exhaust gas tract has a main line with an exhaust gas turbine of a turbocharger and a catalytic convertor downstream of the turbine. The exhaust gas tract has a bypass, by which at least some of the is conductible pa...

Beschreibung
Zusammenfassung:	A drive device for a vehicle with and an exhaust gas tract connected to engine. The exhaust gas tract has a main line with an exhaust gas turbine of a turbocharger and a catalytic convertor downstream of the turbine. The exhaust gas tract has a bypass, by which at least some of the is conductible past a turbine wheel of the turbine such that the exhaust gas is conductible out of the main line at at least one a conducting-out region into the bypass line upstream of the turbine wheel. The bypass exhaust gas flow in the bypass line is conductible into the main line at downstream of the turbine wheel (41) and upstream of the catalytic convertor. To prevent overheating of the catalytic convertor, a cooling device is provided, by which the bypass exhaust gas flow flowing through the bypass line is coolable.
