Abstract

dispositivo de tratamento de escape de trifluxo com tubo de mistura de redutor a presente invenção refere-se a um dispositivo de tratamento de escape que inclui primeiro e segundo substratos posicionados em paralelo dentro de um alojamento. uma placa defletora suporta o substrato, um tubo de entrada e uma tubulação de saída, e define uma porção de uma primeira câmara. as primeiras extremidades dos substratos e a segunda extremidade do tubo de entrada estão em comunicação fluida com a primeira câmara. uma divisória suporta os substratos, o tubo de entrada e a tubulação de saída e define uma porção de uma segunda câmara separa da primeira câmara. as segundas extremidades dos substratos e a segunda extremidade aberta da tubulação de saída estão em comunicação fluida com a segunda câmara. todo o escape flui em uma primeira direção através do tubo de entrada, inverte a direção através dos substratos e inverte a direção novamente para fluir através da tubulação de saída.
