Abstract

resumo aparelho para redução de gás de exaustão que é provido em uma parte da extremidade do tubo de exaustão pela qual a outra parte da extremidade ser conectada a um motor montado sobre uma estrutura principal do equipamento pesado aparelho para a redução de gás de exaustão para equipamento pesado, que pode atender as normas de gases de exaustão dos motores diesel através da provisão de um dispositivo de redução catalítica seletiva (rcs), além de um filtro de particulado de diesel (fpd), e minimizar a influência da vibração devido ao mecanismo de condução através de montagem do filtro de particulado de diesel (fpd) e o dispositivo de redução catalítica seletiva (drc) em uma estrutura de capota. o aparelho para a redução de um gás de exaustão inclui uma estrutura de capota montada em uma lateral da estrutura principal, que é adjacente ao motor para reduzir uma influência devida à vibração do motor; um filtro de particulado de diesel (fpd) tendo uma parte da extremidade que comunica com a outra parte da extremidade do tubo de exaustão, e está montado sobre uma parte da extremidade superior da estrutura da capota, provida com o catalisador de oxidação de diesel (doc) na mesma, e a captura de matérias particuladas; um tubo de mistura, com uma parte da extremidade que comunica com a outra parte da extremidade do filtro de particulado de diesel, uma lateral que se comunica com um dispositivo de injeção injetando um agente de redução; e um dispositivo de redução catalítica seletiva (rcs) montado em uma parte da extremidade superior da estrutura da capota para se comunicar com a outra parte de extremidade do tubo de mistura para acelerar a reação de redução entre o agente redutor injetado e óxidos de nitrogênio (nox) no gás de exaustão.
