Abstract

The method involves initiating regeneration at least when a threshold value for a state of charge of the catalyser or an oxides of nitrogen emission downstream of the catalyser is exceeded by detecting whether the engine is in an idling state and alternatively or in combination, increasing the threshold in the idling state, initiating regeneration only after a defined time and interrupting regeneration if a change to idling occurs. Independent claims are also included for the following: a device for controling oxides of nitrogen regeneration of a storage catalyser.
