Abstract

MéTODO PARA A OPERAçãO DE UM MOTOR DIESEL GRANDE DE DOIS TEMPOS LAVADO LONGITUDINALMENTE E UM MOTOR DIESEL GRANDE DE DOIS TEMPOS LAVADO LONGITUDINALMENTE. A presente invenção refere-se a um método para a operação de um motor diesel grande de dois tempos longitudinalmente lavado (1), tendo um pistão (20) sendo disposto para ser móvel indo e vindo de um cilindro (2) ao longo de uma superfície de deslocamento entre um ponto morto inferior (UT) e um ponto morto superior (OT), em que um combustível é alimentado no cilindro (2) do motor diesel grande (1) por um bocal de injeção, e fendas de lavagem (3) são fornecidas em uma região de entrada do cilindro (2) para o suprimento de uma quantidade predeterminada de ar de lavagem (4). Uma válvula de saída (5) é fornecida em uma cobertura de cilindro do cilindro (2) para a expulsão de um gás de combustão (6), em que, no dito método, um ar fresco (7) disponível em uma pressão ambiente é sugado por um primeiro turbocompressor de gás de exaustão (8, 81) e/ou por um segundo turbocompressor de gás de exaustão (8, 82) e o dito ar fresco (7) é suprido no cilindro (2) como o ar de lavagem (4) a uma pressão de ar de carga predeterminado por meio das fendas de lavagem (3), de modo que uma mistura de gás de ignição seja gerada no cilindro (2) a partir do ar de lavagem (4) e do combustível. De acordo com a invenção, pelo menos um meio de redução (9, 91, 92, 93) para reduzir um fluxo de gás de exaustão através do primeiro turbocompressor de gás de exaustão (8, 81) e/ou através do segundo turbocompressor de gás de exaustão (8, 82) é fornecido, e em que, no dito método, o fluxo de gás de exaustão através do primeiro turbocompressor de gás de exaustão (8, 81) e/ou através do segundo turbocompressor de gás de exaustão (8, 82) é reduzido em dependência de um dado valor de um parâmetro operacional do motor diesel grande (1). Além do mais, a invenção refere-se a um motor diesel grande de dois tempos longitudinalmente lavado (1) para a realização do método.
