Abstract

DISPOSIçãO PARA RECIRCULAçãO DE GASES DE EXAUSTãO DE UM MOTOR DE COMBUSTãO INTERNA DE SUPERCOMPRESSãO. A presente invenção refere-se a uma disposição para recirculação de gases de exaustão em um motor de combustão de supercompressão (1). A disposição compreende uma linha de exaustão (3) pretendida para levar gases de exaustão para fora do motor de combustão (1) uma linha de entrada (6) pretendida para levar o ar acima da pressão atmosférica ao motor de combustão (1) , uma linha de retorno (7) que compreende uma conexão com a linha de exaustão (3) e uma conexão com a linha de entrada (6) , de modo que a linha de retorno (7) é possível de recircular gases de exaustão da linha de exaustão (3) para a linha de entrada (6). A disposição compreende um refrigerador de carga (12) que é resfriado por ar ambiente. O refrigerador de carga (12) é incorporado na linha de entrada (6) à jusante da conexão da linha de retorno (7) com a linha de entrada (6) de modo que, quando os gases de exaustão são retornados por meio da linha de retorno (7), o dito refrigerador de carga (12) resfria uma mistura de gases de exaustão e ar antes da mistura ser levada para o motor de combustão (1).
