Abstract
resumo sistema de escape; sistema de tratamento de escape; e sistema de escape que inclui um sistema de pós- tratamento de escape trata-se de um sistema de escape que inclui um componente de redução catalítica seletiva (scr) e um componente de catalisador de oxidação. o sistema de escape também inclui um sistema de injeção de fluido de tratamento de escape para dispersar um fluido de tratamento de escape em uma corrente de escape a uma localidade adjacente tanto ao componente de scr quanto ao componente de catalisador de oxidação, em que o dispositivo de injeção de fluido de tratamento de escape inclui um tubo comum (common rail) que fornece o fluido de tratamento de escape sob pressão a uma pluralidade de injetores que dosam o fluido de tratamento de escape na corrente de escape. o dispositivo de injeção de fluido de tratamento de escape também inclui um tubo de retorno para retornar o fluido de tratamento de escape não usado à fonte de fluido. 1/1
