Abstract

método para injetar amonia dentro de uma corrente de gas de exaustão. um método para injetar amônia (nh~ 3~) dentro do gás de exaustão à montante do catalisador de um sistema de pos tratamento inclui as etapas de determinar se um evento de reneneração é iminente (14), com base em parâmetros predeterminados, e determinando se os parâmetros de dosagem são insatisfeitos (22). o método (10) ainda incluí as etapas de calcular uma quantidade de nh~ 3~ para encher o catalisador (18) e ajustando a quantidade de nh~ 3~ dosada (22) antes que ocorra o evento de regeneração.
