Abstract
trata-se de um misturador para um sistema de exaustão veicular que inclui um corpo de misturador que define um eixo geométrico central de misturador e que tem uma entrada configurada para receber gás de exaustão de motor e uma saída. o misturador inclui, ainda, um defletor a montante posicionado no interior do corpo de misturador e um defletor a jusante posicionado no interior do corpo de misturador a ser espaçado do defletor a montante em uma direção ao longo do eixo geométrico central de misturador. um dosador define um eixo geométrico de dosador e é posicionado para aspergir um agente redutor em uma área entre o defletor a montante e o defletor a jusante de modo que uma mistura de agente redutor e gás de exaustão saia da saída. a mistura se move através de uma trajetória de fluxo giratória que é de pelo menos 360 graus antes de sair da saída.
