DEVICE AND METHOD FOR DETERMINING THE NEED FOR REGENERATION IN A NOx STORAGE CATALYTIC CONVERTER

摘要

The method involves determining the need for regeneration depending on the power of the internal combustion engine (10) and the remaining oxides of nitrogen storage capacity of the catalyser (18). The instantaneous engine power is taken into account and an acceleration gradient for a predetermined time interval can be taken into account. Independent claims are also included for the following: a device for determining the need for regeneration of a nitrogen oxide storage catalyser.
