Abstract

DISPOSITIVO DE RETRATAMENTO DE GÁS DE EXAUSTÃO. A presente invenção refere-se a um dispositivo de retratamento de gás de exaustão (1) para um sistema de exaustão de um motor de combustão interna, mais preferencialmente de um veículo a motor, compreendendo um alojamento (2), no qual são dispostos pelo menos um elemento de retratamento de gás de exaustão (3) e a jusante do mesmo pelo menos um dispositivo silenciador (4), um caminho de gás de entrada (7), que leva pelo menos desde uma entrada de alojamento (5) para uma saída (9) do elemento do retratamento de gás de exaustão (3) localizado no interior do alojamento (2), com um caminho de gás de exaustão (8) seguindo o caminho de gás de entrada (7), o qual, no interior do alojamento (2) leva a pelo menos um dispositivo silenciador (4) e/ou através do pelo menos um dispositivo silenciador (4), bem como, também, a uma saída de alojamento (6). Um projeto de custo efetivo pode ser obtido se o caminho de gás de entrada (7) tiver uma vedação de gás mais alta do que o caminho do gás de exaustão (8) e/ou se os componentes (11, 12, 14) do dispositivo de retratamento de gás de exaustão (1), limitando o caminho do gás de entrada (7), tiverem uma qualidade de material mais alta do que os componentes (21, 22, 23, 24, 25, 26) do dispositivo de retratamento de gás de exaustão (1) somente limitando o caminho do gás de exaustão (8).
