摘要

Process for regenerating and de-sulfatizing a nitrogen oxides storage catalyst in an internal combustion engine exhaust gas purification device, comprises introducing combustion gases of an air-fuel mixture ignited in a separate chamber to the exhaust gas flowing in from the engine and flowing to the catalyst. Process for regenerating and de-sulfatizing a nitrogen oxides storage catalyst in an internal combustion engine exhaust gas purification device, comprises introducing combustion gases of an air-fuel mixture ignited in a separate chamber to the exhaust gas flowing in from the engine and flowing to the catalyst. The air-fuel mixture is produced and ignited in a ratio of air to fuel so that nitrogen oxides regeneration and/or de-sulfatization of the catalyst is carried out by the combustion gases produced.
