Abstract

Trata-se de um conjunto de saída para um sistema de pós-tratamento que compreende um conduto de saída configurado para receber um gás de escape do sistema pós-tratamento. O conduto de saída define uma primeira abertura através de uma parede lateral do mesmo. Uma passagem de saída é disposta dentro do conduto de saída. A passagem de saída compreende uma primeira extremidade voltada para um lado a montante do conduto de saída e uma segunda extremidade situada a jusante da primeira extremidade. A segunda extremidade é acoplada de forma fluida à primeira abertura. Um orifício é definido através de uma parede lateral de passagem de saída em um local radial que é próximo à parede lateral do conduto de saída. O orifício é configurado para permitir que um sensor seja inserido através dele em uma trajetória de fluxo definida pela passagem de saída. A passagem de saída é configurada para receber uma porção do gás de escape do conduto de saída, de modo que o sensor fique exposto à porção do gás de escape.
