摘要： The present invention relates to an exhaust-gas aftertreatment system which comprises a preferably catalytically active particle filter (wall-flow filter) which is followed in turn by a throughflow monolith (flow-through monolith) which is preferably provided with a catalytically active function. Both components have the same storage functions for gaseous substances present in the exhaust gas of internal combustion engines. The system is suitable in particular for the simultaneous removal of particles and pollutants from the exhaust gas of both predominantly lean-operated internal combustion engines and also of internal combustion engines operated predominantly with a stoichiometric air/fuel mixture. Likewise described is a process for the production and the use of such a system for exhaust-gas aftertreatment.

摘要： The present invention relates to a regulating strategy for a special catalytic converter for exhaust-gas aftertreatment. The catalytic converter concept is distinguished in that at least two nitrogen oxide storage catalytic converters are used in the exhaust section of a vehicle. The first, possibly close-coupled unit is followed by one or more nitrogen oxide storage catalytic converters, which are possibly situated in the underbody of the vehicle. The nitrogen oxide storage catalytic converters are then regenerated as a function of the exceedance of nitrogen oxide threshold vales downstream thereof.

摘要： The invention relates to a method for removing carbon monoxide and hydrocarbons from the exhaust gas of lean-burn internal combustion engines, said exhaust gas being passed over a catalyst which contains platinum supported on one or more refractory supporting materials, pure cerium oxide, and optionally an additional noble metal selected from the group consisting of platinum, palladium, and rhodium, said pure cerium oxide being in close contact with the noble metal. The catalytic activity is regenerated using rich exhaust gas under lean conditions after a threshold temperature load is exceeded.
