Abstract

"DISPOSITIVO PARA AJUSTAR A TEMPERATURA DE GASES DE EXAUSTãO". A presente invenção refere-se a um dispositivo para ajustar a temperatura de gases de exaustão que passam através de um sistema de exaustão (11-17) de um veículo que apresenta um motor de combustão interna (10). O sistema de exaustão é dotado de um filtro de regeneração ativa (14) para coletar partículas da corrente de gás de exaustão. O dispositivo compreende um trocador de calor (12), que apresenta uma primeira passagem de fluxo para uma corrente de gás de exaustão proveniente do manifold de exaustão (11) do motor para o filtro de partículas (14), e uma segunda passagem de fluxo para uma corrente de gás de exaustão proveniente do filtro de partículas (14) para o tubo de saída (17) do sistema de exaustão.
