ABSTRACT:
An exhaust gas purification unit for purifying the exhaust gas from an internal combustion engine which is preferably operated in lean burn mode, in particular a diesel engine used in motor vehicles, has a particulate filter and a SCR catalytic converter arranged in the exhaust pipe in succession in the direction of flow, and a reducing agent supply. Ammonia can be added to the exhaust gas from the internal combustion engine on the entry side of the SCR catalytic converter by the reducing agent supply. A hydrogen-generating unit enriches the exhaust gas from the internal combustion engine with generated hydrogen.
