    摘要: In a method for regenerating a nitrogen oxide storage catalytic converter arranged in an exhaust pipe of an internal combustion engine, a constant value is set in a first regeneration phase for the air/fuel ratio λM of the air/fuel mixture fed to the internal combustion engine when a predeterminable triggering threshold value for the nitrogen oxide concentration in the exhaust gas on the output side of the nitrogen oxide storage catalytic converter is exceeded. The first regeneration phase is followed by a second regeneration phase, in which the time rate of change d λM/dt of the air/fuel ratio λM is set as a function of the mass flow of the exhaust gas flowing through the nitrogen oxide storage catalytic converter or as a function of an internal combustion engine operating variable linked with the mass flow of exhaust gas.

    摘要: A determination of a quality of a reducing agent solution containing ammonia used to reduce nitrogen oxides involves actuating a metering unit that delivers metered quantities of reducing agent solution into an engine's discharged exhaust gas and determining an efficiency value that is at least correlated with the efficiency of the SCR catalytic converter and comparing the efficiency value to a predefinable limit value. If an efficiency value not corresponding to proper functioning of the SCR exhaust emission control system is identified by the comparison, a switch is made to a diagnostic mode in a second method step. If a predefinable deviation of the efficiency value from a limit value is identified after expiration of the second method step time period, a third method step is performed for conditioning the SCR catalytic converter. A fourth step involves an adaptation mode in which a deviation from the efficiency value is determined.
