Abstract
coletor de escape para um motor de combustão, em particular em veículos a motor, método para operar um motor de combustão e veículo a presente invenção diz respeito a um coletor de escape (1) para um motor de combustão, em particular em veículos a motor tendo um sistema de turboalimentação de escape e um sistema de recirculação de gás de escape para recirculação de gás de escape do coletor de escape (1) para a entrada de motor, em que o coletor de escape (1) tem um tubo coletor (4) tendo uma pluralidade de aberturas de influxo (6), que são conectadas às cámaras de combustão do motor de combustão, preferencialmente por meio de pontas de conexão e aberturas de saída (7, 8) para o sistema de recirculação de gás de escape e para o turbocompressor de escape que se ramificam a partir do tubo coletor (4) por meio de conectores, em que as aberturas de saída (7, 8) são atribuídas a um elemento orientador de fluxo que pode ser movido de maneira controlada e que distribui a corrente de gás de escape de forma seletiva para as aberturas de saída (7, 8) em conformidade com parâmetros de operação especificáveis. de acordo com a invenção, é previsto que o elemento orientador de fluxo é formado por uma aba de gás de escape (10) que é montada de forma passível de giro no tubo coletor (4) e por meio da qual a corrente de gás de escape pode ser direcionada tanto para a abertura de saída (7) para o sistema de recirculação de gás de escape quanto também para a abertura de saída (8) para o turbocompressor de escape.
