Abstract

DISPOSIçãO PARA RECIRCULAçãO DE GASES DE ESCAPE DE UM MOTOR DE COMBUSTãO INTERNA TURBOALIMENTADO EM UM VEìCULO. A presente invenção se refere a uma disposição para recirculação de gases de escape de um motor de combustão sobrealimentado (1) em um veículo. A disposição compreende uma linha de admissão (10) para alimentação de ar comprimido ao motor de combustão (1) . A linha de admissão (10) compreende um resfriador de ar de admissão (11) para resfriamento do ar. A disposição também compreende uma linha de retorno (15) que conecta a linha de escape (6) à linha de admissão (10) de modo que seja possível, por meio da linha de retorno (15), recircular os gases de escape a partir da linha de escape (6) para a linha de admissão (10) . A linha de retorno (15) compreende um resfriador EGR (17) para resfriamento dos gases de escape recirculantes. O resfriador EGR (17) e o resfriador de ar de admissão (11) são dispostos próximos ao motor de combustão (1) no lado frio do motor de combustão (1), em que um tubo de admissão ramificado (24) é fixado.
