Abstract

é fornecido um veículo do tipo para montar, em que a variação no desempenho de purificação da purificação do gás de escape pode ser restringida. uma unidade de mecanismo motor montada em um veículo do tipo para montar 1 inclui: um corpo principal de mecanismo motor 20 que inclui uma câmara de combustão 36; um membro de passagem de escape 43 que permite que o gás de escape flua a partir da câmara de combustão 36 para uma porta de descarga 42e; um catalisador a montante 46, que é o catalisador mais a montante no membro de passagem de escape 43 na direção de fluxo do gás de escape; um detector de oxigênio 92f; e uma porção de redução de adesão de fósforo 44. a porção de redução de adesão de fósforo 44 e o detector de oxigênio 92f são fornecidos no membro de passagem de escape 43, entre a câmara de combustão 36 e o catalisador a montante. uma camada de catalisador 49 do catalisador a montante 46 inclui um metal nobre e purifica o gás de escape. a porção de redução de adesão de fósforo 44 inclui pelo menos uma dentre uma camada de captura de fósforo 44a ou uma estrutura de captura de fósforo 44b e restringe a aderência de fósforo à camada de catalisador 49.
