Abstract

"MéTODO DE DECOMPOR DIóXIDO DE NITROGêNIO EM MONóXIDO DE NITROGêNIO EM UM GáS DE ESCAPAMENTO DE UM MOTOR A DIESEL, SISTEMA DE ESCAPAMENTO PARA UM MOTOR A DIESEL, APARELHO, E, VEìCULO". Método de decompor NO~ 2~ em NO em um gás de escapamento de um motor de combustão interna de queima pobre compreende as etapas de contatar um óxido metálico ácido selecionado dentre o grupo consistindo de zeólitos, titânia dopada com tungstênio, sílica-titania, zircónia-titânia, gama-alumina, sílica-alumina amorfa e misturas de quaisquer dois ou mais dos mesmos, com uma mistura de gás compreendendo o gás de escapamento, ajustar a composição da mistura de gás, por injeção de hidrocarboneto ai a uma taxa que muda durante o curso de um ciclo de trabalho de modo que, em média sobre o ciclo de trabalho, a relação de hidrocarboneto C1 óxidos de nitrogênio da mistura de gás contatando o óxido metálico ácido é de 0,1 a 2,0 e passando o gás efluente diretamente para a atmosfera, opcionalmente via primeiro contato da mistura de gás com um catalisador de oxidação de hidrocarboneto.
