EXHAUST SYSTEM FOR AN INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE AND METHOD FOR OPERATING AN EXHAUST SYSTEM

摘要

The invention relates to an exhaust system (3) for an internal combustion engine (2) of a motor vehicle, having an SCR catalytic converter (11) for carrying out selective catalytic reduction of pollutants contained in the exhaust gas of the internal combustion engine (2) using a reducing agent, wherein the SCR catalytic converter (11) is arranged downstream of a turbine (7) of an exhaust gas turbocharger (8), and a feed device (5) for feeding the reducing agent into the exhaust gas at a feed position (6) arranged upstream of the turbine (7) is provided. In this context there is provision that a nitrogen oxide storage catalytic converter (4) is arranged upstream of the feed position (6). The invention also relates to a method for operating an exhaust system (3).
