摘要

Process for the simultaneous reaction of nitrogen oxides and soot particles in the exhaust gas of a diesel engine comprises feeding the exhaust gas that has been passed over a NOx absorber to a particle filter arranged downstream so that burning of the soot particles occurs in the filter with exhaust gas heating above the diesel exhaust gas temperature produced by a controlled regeneration with oxygen-deficient exhaust gas in the storage catalyst.
