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 de um motor de combustão de supercompressão (1) que é resfriado por um primeiro sistema de refrigeração por meio de um primeiro refrigerante. A disposição compreende uma linha de retorno (10) que conecta uma linha de exaustão (3) em uma linha de entrada (7) para suprimento de ar para o motor de combustão, de modo que é possível recircular os gases de exaustão por meio da linha de retorno (10). A disposição compreende um primeiro refrigerador de EGR (12a) em que os gases de exaustão recirculando na linha de retorno (10) são resfriados, como uma primeira etapa, pelo primeiro refrigerante no primeiro sistema de refrigeração. A disposição compreende um segundo refrigerador de EGR (12h) em que os gases de exaustão recirculando na linha de retorno (10) são resfriados, como uma segunda etapa, por um segundo refrigerante em um segundo sistema de refrigeração, cujo segundo refrigerante é adaptado para estar a uma temperatura que corresponde substancialmente à temperatura das adjacências quando é levado para dentro do segundo refrigerador de EGR (12b).
