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.
