Abstract

tubulação de exaustão para um motor de combustão interna, em particular em veículos a motor. a invenção refere-se a uma tubulação de exaustão para um motor de combustão interna, em particular em veículos a motor, com turbo carregamento de exaustão e um dispositivo de recirculação de gás de exaustão para recircular o gás de exaustão a partir da tubulação de exaustão para a entrada de motor, onde a tubulação de exaustão compreende um tubo dianteiro com várias aberturas dce fluxo de entrada conectadas às câmaras de combustão do motor de combustão interna através de peças de conexão, e aberturas de saída ramificando a partir do tubo dianteiro através de ramificações de conexão para a recirculação de gás de exaustão e para o turbo carregador de exaustão. para alcançar uma taxa de recirculação de gás de exaustão alta e uma pressurização efetiva do turbo carregador de exaustão com o gás de exaustão, é proposto que pelo menos um elemento-guia de fluxo (10) seja disposto no tubo dianteiro (4) perto das aberturas de saída (7, 8) que dividem o fluxo de gás de exaustão em duas aberturas de saída (7, 8) de forma alvo.
