Patent ID: 8297046

Claim:
An installation for aftertreatment of exhaust gas generated by a diesel engine of a motor vehicle, said installation comprising: a nitrogen oxide storage catalytic converter configured for temporarily storing nitrogen oxides contained in the exhaust gas during adsorption operating phases with a lean exhaust gas air ratio and for releasing and reducing stored nitrogen oxides during regeneration operating phases with a rich exhaust gas air ratio, wherein the nitrogen oxide storage catalytic converter is configured to generate ammonia by reducing stored nitrogen oxides during the regeneration operating phases; a particulate filter arranged upstream of the nitrogen oxide storage catalytic converter; a first oxidation catalytic converter arranged as a first exhaust gas aftertreatment component, as seen in a direction of flow of the exhaust gas; a second oxidation catalytic converter arranged downstream of the nitrogen oxide storage catalytic converter, said second oxidation catalytic converter having a lower precious metal loading than the first oxidation catalytic converter; a reducing agent supplying device configured to feed fuel into the exhaust gas stream, as a reducing agent, wherein said reducing agent supplying device is configured to feed fuel into the exhaust gas stream upstream of the particulate filter; and an SCR catalytic converter arranged between the nitrogen oxide storage catalytic converter and the second oxidation catalytic converter.
