Abstract

A invenção diz respeito a um dispositivo (10) para misturar um fluxo de gás de escape com um aditivo, particularmente um agente redutor. O dispositivo (10) possui um tubo de mistura (14) para misturar o fluxo de gás de escape com o aditivo. O dispositivo (10) possui um primeiro tubo defletor (12) para desviar o fluxo de gás de escape, particularmente em 180°. O fluxo de gás de escape pode ser alimentado ao tubo de mistura (14) no lado da extremidade por meio do primeiro tubo defletor (12). O primeiro tubo defletor (12) possui uma região de fixação (28) para fixação de um injetor de aditivo (30) ao primeiro tubo defletor (12). O primeiro tubo defletor (12) possui uma região de parede geradora de redemoinho (26) que é disposta no lado da extremidade em relação ao tubo de mistura (14) e é configurada para transmitir um redemoinho ao fluxo de gás de escape. O dispositivo (10) possibilita uma disposição que é favorável em termos de espaço de instalação, uma vez que o primeiro tubo defletor (12) é usado tanto para a geração de redemoinho do lado da extremidade quanto para a fixação do injetor de aditivo (30).
