Abstract

uma porção do tubo externo (70) de um tubo de escape (10, 10a a 10c), a porção estando localizada mais próxima a um silenciador (56) que um catalisador (58), é configurada como uma saída (84, 90, 96) a partir da qual o gás de escape purificado descarregado a partir do catalisador (58) é induzido a fluir para o silenciador (56). um dentre o comprimento (lpa a lpc) da saída (84, 90, 96), que é medido na direção de cima - debaixo, e o comprimento (lha a lhc) da mesma, que é medido na direção da esquerda - a direita, é menor que o diâmetro (d) do catalisador (58), e o outro é maior que o diâmetro (d) do catalisador (58).
