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...
