Abstract
ARRANJO PARA TRATAMENTO POSTERIOR DE GáS DE ESCAPE EM MOTORES DE COMBUSTAO INTERNA E MéTODO PARA A FABRICAçãO DE UM ARRANJO PARA TRATAMENTO POSTERIOR DE GáS DE ESCAPE EM MOTORES DE COMBUSTAO INTERNA. Arranjo para o tratamento posterior em motores de combustão interna operados com excesso de ar, tais como motores diesel e motores Otto com injeção direta, sendo que o arranjo para a redução de áxidos de nitrogênio contém pelo menos um catalisador de armazenamento de NO~ X~ instalado no tubo de gás de escape de um motor de combustão interna, no qual são armazenados óxidos de nitrogênio em fases operacionais pobres e esses áxidos de nitrogênio armazenados serem reduzidos em fases operacionais ricas. Está previsto dispor entre o gás de escape e pelo menos um catalisador de armazenamento de NO~ X~ e/ou em curso ascendente de pelo menos um catalisador de armazenamento de NO~ X~, pelo menos uma peneira molecular, que retém diáxido de enxofre de pelo menos um catalisador de armazenamento de NO~ X~.
