Abstract

DISPOSIçãO PARA CONTROLE DE PULSOS DE PRESSãO DE EXAUSTãO EM UM MOTOR DE COMBUSTãO INTERNA. A presente invenção se refere a uma disposição para controle de pulsação de pressão de exaustão em um motor de combustão interna (10) compreendendo seis cilindros (12). O motor de combustão interna (10) também compreende uma entrada (admissão) (13) para suprimento de ar para os cilindros (12), e um manifold de exaustão (14) para entrega de gases de exaustão a partir dos cilindros (12). O manifold de exaustão (14) está proporcionado com uma primeira saída (31) para um sistema de exaustão (22) e com uma segunda saída (32) para um conduto (24) para alimentação de gases de exaustão de volta, por intermédio de um circuito de EGR, a partir de pelo menos um dos cilindros (12) do motor de combustão interna (10) para referida entrada (13). Pelo menos um dos cilindros (12) está adaptado para enriquecimento dos gases de exaustão com hidrocarboneto não queimado com uma visão para regeneração de uma unidade de pós-tratamento de gás de exaustão (23) situada no sistema de exaustão (22). Em concordância com a presente invenção, a referida disposição para controle de pulsação de pressão de exaustão em um motor de combustão interna (10) está caracterizada pelo fato de que apresenta uma configuração especial do manifold de exaustão (14) que resulta em separação de gás de regeneração a partir de gás de EGR no manifold de exaustão (14).
