Abstract
sistema de scr e método para purificar gases de escape em um sistema de scr. a invenção refere-se a um método para, por meio de um agente redutor, purificar gás de escape em um fluxo de gás de escape de um motor (230) em um sistema de scr que compreende duas configurações de catalisador de scr (260, 265) dispostas em série no dito fluxo de gás de escape, que compreende as etapas de: - determinar continuamente um teor de amônia no dito gás de escape a jusante de uma primeira configuração de catalisador de scr (260); - determinar continuamente um teor de nox no dito gás de escape a jusante de uma segunda configuração de catalisador de scr (265), a qual é disposta a jusante da dita primeira configuração de catalisador de scr; - realizar a dita purificação parcialmente em um primeiro estado (estado1) que compreende superdosagem evidente do dito agente redutor na dita primeira configuração de catalisador de scr (260) e parcialmente em um segundo estado (estado2) que compreende subdosagem evidente do dito agente redutor na dita primeira configuração de catalisador de scr (260); e - mudar entre o dito primeiro estado (estado1) e o dito segundo estado (estado2) com base no dito teor de amônia determinado e no dito teor de nox no dito gás de escape. a invenção refere-se também a um produto de programa de computador que compreende código de programa (p) para um computador (200; 210) para implantar um método de acordo com a invenção. a invenção refere-se também a um sistema de scr e um veículo a motor o qual é equipado com o sistema de scr.
