Abstract
1 / 1 resumo “sistema de escape para tratar um gã�s de escape de um motor de combustãƒo internaâ€� um sistema de escape para tratar gã¡s de escape de um motor de combustã£o interna ã© descrito. o sistema compreende um catalisador de trãªs vias (twc), um catalisador reformador de combustãvel localizado a jusante do twc, e um meio de fornecimento de combustãvel localizado a montante do catalisador reformador de combustãvel. o gã¡s de escape ã© dividido em duas porã§ãµes. a primeira porã§ã£o do gã¡s de escape desvia do twc e faz contato com o catalisador reformador de combustãvel na presenã§a de combustãvel adicionado a partir do meio de fornecimento de combustãvel, e ã© entã£o reciclado de volta para a admissã£o de motor. a segunda porã§ã£o do gã¡s de escape ã© contacta com o twc e ã© entã£o utilizada para aquecer o catalisador reformador de combustãvel antes de ser expelida para a atmosfera. o sistema de escape permite mã¡xima troca de calor pelo gã¡s de escape.
