Abstract
1 / 1 resumo âsistema para tratar gases de exaustão contendo no x de um motor, e, mãtodo para tratar uma corrente de gãs de exaustão do motor contendo no e fuligemâ x um sistema para tratar gases de exaustã£o de um motor de combustã£o e um mã©todo para usar o mesmo que resulta em maior conversã£o de nox durante partida do motor. o sistema inclui um monã³lito de fluxo atravessante de scr compacto (20) instalado a montante de um filtro de fluxo de parede de scr acoplado de forma compacta (22), em que o monã³lito de fluxo atravessante de scr compacto pode ser extrusado ou feito de um substrato de parede fina, de maneira tal que o monã³lito de fluxo atravessante de scr tem um menor volume com menor capacidade tã©rmica e maior carregamento do catalisador em relaã§ã£o ao filtro de fluxo de parede de scr.
