Abstract

ARRANJO PARA RECIRCULAçãO DE GASES DE EXAUSTãO EM UM MOTOR à COMBUSTãO INTERNO SUPERCARREGADO A presente invenção diz respeito a um arranjo para recirculação de gases de exaustão de um motor de combustão supercarregado (1). O arranjo compreende uma tubulação de exaustão (3) intencionada a conduzir gases de exaustão para fora do motor de combustão (1), uma tubulação de entrada (7) intencionada a conduzir ar acima da pressão atmosférica para o motor de combustão (1), uma tubulação de retorno (10) que conecta a tubulação de exaustão (3) à tubulação de entrada (7) de forma que por meio da tubulação de retorno (10) é possível a recirculação de gases de exaustão da tubulação de exaustão (3) para a tubulação de entrada (7), e um refrigerador EGR (12) em que os gases de exaustão de recirculação na tubulação de retorno (10) são resfriados por um refrigerante antes de serem misturados com o ar na tubulação de entrada (7). Os gases de exaustão no refrigerador EGR (12) são resfriados por um refrigerante circulante que é adaptado para estar em uma temperatura substancialmente correspondente à temperatura dos arredores quando for conduzido para dentro do refrigerador EGR (12).
