ABSTRACT:
The invention relates to a device and method for determining the need for regeneration in a NOxstorage catalyst (18) arranged in the exhaust train (12) of an at least periodically lean-operating internal combustion engine (10) for a motor vehicle. According to the invention, the need for regeneration is determined according to the engine power (P) of the internal combustion engine (10) and the remaining NOxstorage capacity of the NOxstorage catalyst.
