Abstract
a presente invenção se refere a um coletor para receber gases de exaustão de um motor de combustão interna de múltiplos cilindros (1). o motor de combustão interna (1) possui uma tal ordem de disparo que o duto (4a, 4b) no coletor (4a, 4b) recebe gases de exaustão a partir de dois cilindros (c2, c4, c7, c8) durante um estágio de sobreposição, simultaneamente através de uma abertura de entrada (3a2, 3b3) disposta à montante e a partir de uma abertura de entrada (3a4, 3b4) disposta à jusante no duto (4a, 4b). o duto (4a, 4b) compreende uma área transversal substancialmente constante, exceto em uma área (a, b), que é localizada em uma posição em conexão com a abertura de entrada disposta à jusante (3a4, 3b4) das duas aberturas de entrada (3a2, 3a4, 3b3, 3b4), recebendo gases de exaustão simultaneamente. a área (a, b) possui uma geometria de forma a facilitar o recebimento e o fluxo de gases de exaustão na direção pré-determinada no duto (4a, 4b), em ocasiões em que as duas aberturas de entrada (3a2, 3a4, 3b3, 3b4) recebem gases de exaustão simultaneamente.
