Abstract: The invention relates to a system and a control method for an exhaust aftertreatment system (10) of an engine (12) in which one or more constituents of the exhaust gas are oxidized in an oxidation catalyst (20) and one or more constituents of the exhaust gas are deoxidized in a selective-catalytic-reduction catalyst (70), wherein the exhaust gas flows from the oxidation catalyst (20) to the selective-catalytic-reduction catalyst (70). It is.

Abstract: Method and device for reduction of a gas component in an exhaust gas flow of a combustion engine (1) that is adapted for operation by a lean air/fuel mixture. An exhaust pipe (21) is included for transport of the exhaust gas flow from the engine (1). A separation unit (22) is also included that is arranged along the exhaust pipe (21), which separation unit (22) has a wall structure (32) of a material which provides separation of the gas component from the exhaust gas flow by means of a selective passage of the gas component before other gas components in the exhaust gas flow. The method provides for a reduction and a separation unit that is intended to be utilized during such a reduction. An improved reduction of in particular NOx compounds from a so-called “lean-burn” engine is also provided.
