Patent ID: 7814747

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, releasing and reducing stored nitrogen oxides during regeneration operating phases with a rich exhaust gas air ratio; an SCR catalytic converter arranged downstream of the nitrogen oxide storage catalytic converter, said SCR catalytic converter being configured to receive and store ammonia generated by the nitrogen oxide storage catalytic converter, and to reduce nitrogen oxides in the exhaust gas with the stored ammonia; a particulate filter arranged upstream of the SCR catalytic converter and downstream of the nitrogen oxide storage catalytic converter; and an oxidation catalytic converter arranged as a first exhaust gas aftertreatment component, as seen in the direction of flow of the exhaust gas.
