Exhaust gas treatment device for e.g. diesel engine, has nitrogen oxide storage component provided proximate to substrate of diesel particulate filter, and catalyst provided for selective catalytic reduction of nitrogen oxide in gas

The device (100) has a diesel particulate filter (110) provided with a substrate. A nitrogen oxide storage component stores nitrogen oxide from exhaust gas (1) supplied from an internal combustion engine. A selective catalytic reduction (SCR)-catalyst (120) is provided for selective catalytic reduct...

Beschreibung
Zusammenfassung:	The device (100) has a diesel particulate filter (110) provided with a substrate. A nitrogen oxide storage component stores nitrogen oxide from exhaust gas (1) supplied from an internal combustion engine. A selective catalytic reduction (SCR)-catalyst (120) is provided for selective catalytic reduction of the nitrogen oxide in the gas, which is delivered from the catalyst. The storage component is provided proximate to the substrate. The substrate is made of cordierite or silicon carbide. The filter is arranged in a secondary exhaust line running parallel to a primary exhaust gas line. Die Erfindung betrifft eine Vorrichtung zur Behandlung von Abgasen eines Verbrennungsmotors. Eine erfindungsgemäße Vorrichtung zur Behandlung von Abgasen eines Verbrennungsmotors weist einen Dieselpartikelfilter (110, 210, 310, 430), welcher ein Dieselpartikelfiltersubstrat aufweist, eine NOx-Speicherkomponente zum Speichern von Stickoxiden aus dem vom Verbrennungsmotor zugeführten Abgas und einen stromabwärts des Dieselpartikelfilters (110, 210, 310, 430) angeordneten SCR-Katalysator (120, 320, 420) zur selektiven katalytischen Reduktion von Stickoxiden im dem SCR-Katalysator (120, 320, 420) zugeführten Abgas auf, wobei die NOx-Speicherkomponente unmittelbar auf dem Dieselpartikelfiltersubstrat vorgesehen ist.
