摘要： The invention relates to a device for the purification of exhaust gases for an exhaust strand of an internal combustion engine, having an exhaust-gas duct which is of multi-flow design in a predefined region and which has a plurality of partial exhaust strands (4, 5), and having a dosing device (14), by means of which a predefined quantity of a reducing agent can be dosed into the exhaust-gas duct in the region upstream of a catalytic converter arrangement (7, 8) at predefined times. According to the invention, each of the partial exhaust strands (4, 5) is assigned a dosing duct (19, 20) which branches off from a single dosing device (14), wherein a predefined proportion of the dosed reducing agent quantity can be supplied via the dosing ducts (19, 20) to each partial exhaust strand (4, 5).

摘要： The invention relates to a device and to a method for purifying exhaust gases for an internal combustion engine, having a multi-flow exhaust system which, at least in regions, has a plurality of partial exhaust strands and in which are arranged an NOx storage catalytic converter device and an SCR catalytic converter device. According to the invention, the NOx storage catalytic converter device (7) and the SCR catalytic converter device (9) are arranged so as to be distributed between different partial exhaust strands (6, 8) in such a way that, in the event of a nitrogen oxide store of the NOx storage catalytic converter device (7) being filled with nitrogen oxides, for a predefined time period, a predefined quantity of an exhaust-gas flow (16) generated by a substoichiometric rich mode of the internal combustion engine (2) flows via the NOx storage catalytic converter device (7) for the production of a reducing agent, in particular ammonia, to the SCR catalytic converter device (9), in which the produced reducing agent, in particular ammonia, can be stored.
