EXHAUST-GAS TREATMENT DEVICE AND METHOD FOR OPERATING AN EXHAUST-GAS TREATMENT DEVICE

摘要

The invention relates to an exhaust-gas treatment device (10) for a vehicle, having an SCR catalytic converter (24) for reducing nitrogen oxides in the exhaust gas of an internal combustion engine (12). At least one turbocharger (16, 18) is connected in front of the SCR catalytic converter (24). A reducing agent can be introduced into the exhaust gas by means of a metering device (26) at an introduction point which is preferably arranged upstream of a turbine (28) of the at least one turbocharger (18). An oxidation catalytic converter (22) is arranged upstream of the introduction point. Furthermore, the invention relates to a method for operating an exhaust-gas treatment device (10) of this type.
