ABSTRACT:
In a device and a method for removing nitrogen oxides from the exhaust of an internal combustion engine which is operated predominantly with an excess of air, the internal combustion engine is assigned an exhaust system having a nitrogen oxide reduction catalytic converter which comprises two catalytic converter parts, whose reducing agent filling levels can be determined. Metering of a reducing-agent-containing additive into the exhaust gas of the internal combustion engine takes place as a function of the reducing agent filling level of the first catalytic converter part and/or of the second catalytic converter part.
