Abstract

MéTODO PARA A OPERAçãO DE UM MOTOR A DIESEL GRANDE DE DOIS TEMPOS LONGITUDINALMENTE LAVADO E MOTOR A DIESEL GRANDE LONGITUDINALMENTE LAVADO. A presente invenção refere-se a um método para a operação de um motor a diesel grande de dois tempos longitudinalmente lavado (1), no qual fendas de lavagem (4) são providas em uma região de entrada (2) de um cilindro (3) para o suprimento de uma quantidade predeterminada de ar de lavagem, e uma válvula de saída (7) é írovida em uma tampa de cilindro (5) do cilindro (3) para a expulsão de um gás de combustão (6). No método da presente invenção, um ar fresco (8) disponível em uma pressão ambiental (Po) é aspirado por um turbocompressor de gás de exaustão (9) e é suprido para o cilindro (3) como ar de lavagem (10) a uma pressão de ar de carga predeterminada (PL) através das fendas de lavagem (4), de modo que uma mistura de gás de ignição (11) seja gerada no cilindro (3) a partir do ar de lavagem (10) e do gás de combustão (6). De acordo com a presente invenção, um meio para aumentar pressão (12, 121) para o aumento da pressão de ar de carga (PL) é provido, e um volume reduzido de ar de lavagem (VL) é suprido para o cilindro (3) a uma pressão de ar de carga elevada (PL). Além disso, a presente invenção refere-se a um motor a diesel de dois tempos longitudinalmente lavado (1) para a execução do método.
