Abstract

DIFUSOR MúLTIPLO PARA UM MOTOR A COMBUSTãO DE PISTãO ALTERNATIVO E UM MOTOR A COMBUSTãO DE PISTãO ALTERNATIVO. A presente invenção refere-se a um difusor múltiplo (1) para um motor a combustão de pistão alternativo, em particular a um motor diesel de dois tempos grande, em que o difusor múltiplo (1) inclui um alojamento do difusor (4) divergindo desde uma entrada do difusor (2) até uma saída do difusor (3) ao longo de um eixo longitudinal (L), com uma inserção de difusor (5, 51, 52, 53) disposta no interior do alojamento do difusor (4). A entrada do difusor (2) é conectável a uma saída (6) de um turbo-alimentador de gás de exaustão (7) e a saída do difusor (3) é conectável a um resfriador de ar de carregamento (8) do motor a combustão de pistão alternativo, de forma que no estado operacional do motor a combustão de pistão alternativo pode ser introduzido ar puro (9), desde o turbo-alimentador de gás de exaustão (7) via o difusor múltiplo (1), dentro do resfriador de ar de carregamento (8). De acordo com a invenção o difusor múltiplo (1) é feito assimetricamente em relação ao eixo longitudinal (L). A invenção refere-se, ainda mais, a um motor a combustão de pistão alternativo, em particular a um motor diesel de dois tempos grande, com um difusor múltiplo (1) de acordo com a invenção.MULTIPLE DIFFUSER FOR AN ALTERNATIVE PISTON COMBUSTION ENGINE AND AN ALTERNATIVE PISTON COMBUSTION ENGINE. The present invention relates to a multiple diffuser (1) for an reciprocating piston combustion engine, in particular to a large two-stroke diesel engine, wherein the multiple diffuser (1) includes a diverging diffuser housing (4). from a diffuser inlet (2) to a diffuser outlet (3) along a longitudinal axis (L), with a diffuser insert (5, 51, 52, 53) disposed within the diffuser housing (4) . The diffuser inlet (2) is connectable to an outlet (6) of an exhaust gas turbocharger (7) and the diffuser outlet (3) is connectable to a charge air cooler (8) of the engine. reciprocating piston combustion, so that in the operating state of the engine reciprocating piston combustion fresh air (9) can be introduced from the exhaust gas turbocharger (7) via the multiple diffuser (1) into the cooler charging air (8). According to the invention the multiple diffuser (1) is made asymmetrically with respect to the longitudinal axis (L). The invention further relates to an reciprocating piston combustion engine, in particular a large two-stroke diesel engine with a multiple diffuser (1) according to the invention.
