Abstract
disposições de conduto de dosagem para sistema de póstratamento de escape. trata-se de um dispositivo de pós-tratamento que inclui guias de fluxo dispostos dentro de um conduto de dosagem. o escape entra através de uma região perfurada do conduto de dosagem e passa através dos guias de fluxo. os guias de fluxo induzem redemoinho ou outra turbulência para misturar o reagente injetado com o gás de escape. vários tipos de guias de fluxo incluem palhetas fixas em cantiléver, passagens de guia e aberturas com aletas de um segundo conduto. alguns tipos de guias de fluxo induzem a mistura localizada para inibir a formação de depósitos na unidade de montagem de dosador. outros tipos de guias de fluxo induzem a mistura a jusante do conduto de dosagem.
