Abstract
resumo da patente de invenção para: “sistema de tratamento de exaustão com catalisador de nox baixo de hidrocarbonetos”. um sistema para tratamento de uma corrente de exaustão a partir de um motor inclui uma passagem de exaustão principal adaptada para receber a corrente de exaustão a partir do motor. uma ramificação lateral está em comunicação com a passagem de exaustão principal. uma unidade de regeneração é posicionada dentro da ramificação lateral para a combustão de um combustível e aquecimento da exaustão que flui através da passagem de exaustão principal. um catalisador de nox baixo é posicionado dentro da passagem de exaustão principal a jusante da unidade de regeneração. um injetor de redutor é posicionado a jusante da unidade de regeneração e a montante do catalisador de nox baixo para injetar as partículas redutoras para a corrente de exaustão. um controlador opera a unidade de regeneração para aumentar a temperatura de exaustão, bem como opera o injetor de redutor para reduzir nox no catalisador de nox baixo.
