Abstract

sistemas e métodos para fornecer fluxo de gás de escape uniforme para um componente de pós-tratamento. a presente invenção refere-se a um conjunto de entrada para uma carcaça contendo um componente de pós-tratamento de um sistema de pós-tratamento que compreende um conduto de entrada configurado para ser disposto de modo substancialmente perpendicular a um eixo geométrico longitudinal da carcaça. um conduto de redirecionamento de fluxo está disposto a jusante do conduto de entrada e é acoplado à extremidade da carcaça. uma pluralidade de protuberâncias se projeta a partir de uma parede lateral do conduto de redirecionamento de fluxo em direção a uma face de entrada do componente de pós-tratamento e são configuradas para fornecer um fluxo de gás de escape uniforme para a face de entrada. alternativamente, uma placa de distribuição de fluxo tendo uma pluralidade de fendas definidas de modo substancialmente perpendicular ao eixo geométrico longitudinal, está disposta no conduto de redirecionamento de fluxo, a placa sendo inclinada em relação ao eixo geométrico longitudinal. as fendas são configuradas para fornecer um fluxo de gás de escape uniforme para a face de entrada.
