Embodiment Construction

[0039] figure 1 An exhaust gas treatment unit 1 according to a first embodiment is shown. The exhaust gas treatment unit 1 consists of a housing 2 and a tube 5 , wherein the tube 5 is arranged concentrically in the housing 2 and forms an inflow region 6 for exhaust gas 7 . Exhaust gas 7 enters the housing 2 through the first end 3 . The tube 5 is correspondingly open towards the first end 3 of the housing 2 , with the result that the exhaust gas 7 which has entered there flows through the tube 5 in the direction towards the second end 4 . The tube 5 or the inflow region 6 has a tube inner diameter 25 . The second end 4 is of closed design, with the result that the exhaust gases 7 are deflected here. In the downstream part of the pipe 5 , the exhaust gas 7 is divided into a first partial exhaust gas flow 11 and a plurality of second partial exhaust gas flows 13 . A first part of the exhaust gas flow 11 leaves the pipe 5 via an outlet region 10 arranged adjacent to the secon...

Abstract

An exhaust gas treatment unit (1), comprising at least a housing (2) with a first end face (3) and an oppositely arranged second end face (4), having a housing (2) extending from the first end face (3) to the second end face ( 4) The pipe (5) for the inflow region (6) of the exhaust gas (7) has a deflection region (8) for the exhaust gas (7) in the region of the second end face, and has a pipe (5) and A recirculation zone (9) extending between the housings (2). In the deflection zone (8), the exhaust gases (7) are mixed and conveyed into the recirculation zone (9). A method for mixing exhaust gas (7) in an exhaust gas treatment unit (1) is also provided.

Description

technical field [0001] The invention relates to a compact exhaust gas treatment unit in which mixing of exhaust gases takes place and to a method for mixing exhaust gases. In particular, the mixing of the exhaust gases takes place simultaneously with the treatment of the exhaust gases with additives or reagents. Background technique [0002] Due to the continuous increase in traffic and / or increasingly stringent standards for exhaust gases, it is important in the case of vehicles with internal combustion engines that the exhaust gases from the internal combustion engine should be cleaned efficiently. For this purpose, the prior art provides exhaust gas purification systems in which the exhaust gas from an internal combustion engine passes over a catalytically active surface and, with the help of a catalyst material deposited on said surface, pollutants in the exhaust gas such as nitrogen oxides, soot Particulates, carbon monoxide, hydrocarbons, etc. are converted into subst...
