Abstract
A catalytic converter assembly for nitrogen oxide reduction in the exhaust gas of an internal combustion engine, in particular a Diesel engine, includes a catalytic converter through which exhaust gas can flow in a given flow direction. The catalytic converter has a catalyst carrier and a catalytically active layer. The catalytic converter has a reducing agent storage capacity per unit of length being increased in the given flow direction.
