Abstract

Abstract Process for desulphurising an exhaust gas purifier (5) of a diesel engine (1) containing a NOx storage (7) comprises: (a) feeding exhaust gas-increasing measures to an oxidation catalyst (6); (b) producing an almost oxygen-free exhaust gas stream containing 1-10% CO after reaching the lowest desulphurisation temperature necessary for desulphurisation; and (c) returning to normal engine operating conditions after running the necessary regeneration time of the NOx storage (7). An apparatus for use with the above process is also claimed.
