Abstract

a presente invenção refere-se a um sistema de gás de exaustão (10) para um motor de combustão interna (2), que compreende um sistema de purificação (34) de redução catalítica seletiva (scr), compreendendo um arranjo de injeção (28) para adicionar um agente redutor (30) a um fluxo de gases de exaustão (22) e uma câmara de vaporização cilíndrica essencialmente circular (41) compreendendo uma extremidade de entrada (48) e uma extremidade de saída (49). a câmara de vaporização (41) está disposta em conexão de fluido com um meio gerador de redemoinho (60), que proporciona movimento de redemoinho para o fluxo de gás de exaustão (22) e para o agente redutor dentro da câmara de vaporização (41). a extremidade de saída (50) da câmara de vaporização (41) está disposta em ligação de fluido com um meio retardador de turbilhonamento (70) organizado para retardar o movimento de turbilhonamento do fluxo de gás de exaustão (22) e do agente redutor dentro da câmara de vaporização (41).
