Abstract

SISTEMA DE EXAUSTãO PARA UM MOTOR DE COMBUSTãO INTERNA DE QUEIMA POBRE VEICULAR, MOTOR A DIESEL, E, MéTODO DE REDUZIR Nox NO GáS DE EXAUSTãO DE UM MOTOR DE COMBUSTãO INTERNA DE QUEIMA POBRE VEICULAR Um sistema de exaustão para um motor de combustão interna de queima pobre veicular compreende um absorvente de NOx, um injetor de redutor (78) disposto a montante do absorvente de NOx e meio (50), quando em uso, para controlar a adição de redutor, no qual o meio de controle de adição de redutor fornece redutor ao absorvente de NOx em todas as velocidades do veículo em um ciclo de funcionamento em uma taxa que é predeterminada para se correlacionar com uma conversão de NOx desejada na velocidade de ciclo de funcionamento média do veículo.
