Abstract
Die vorliegende Erfindung betrifft eine Einleiteinrichtung (16) für eine Abgasrückführeinrichtung (13) mit einem Frischluftkanalabschnitt (32) zum Führen von Frischluft und mit einem Rückführkanalabschnitt (33) zum Führen von rückgeführtem Abgas, wobei der Rückführkanalabschnitt (33) den Frischluftkanalabschnitt (32) in der Umfangsrichtung umschlingt und dabei wenigstens eine radiale Einlassöffnung (36) des Frischluftkanalabschnitt (32) abdeckt, wobei der Rückführkanalabschnitt (33) durch die jeweilige Einlassöffnung (36) fluidisch mit dem Frischluftkanalabschnitt (32) verbunden ist.The present invention relates to an inlet device (16) for an exhaust gas recirculation device (13) having a fresh air duct section (32) for guiding fresh air and with a return duct section (33) for guiding recirculated exhaust gas, the return duct section (33) forming the fresh air duct section (32) the circumferential direction wraps around thereby covering at least one radial inlet opening (36) of the fresh air channel section (32), wherein the return channel section (33) is fluidically connected to the fresh air channel section (32) through the respective inlet opening (36).
Ein verbesserter Schutz vor Verunreinigungen wird erreicht, wenn in oder an der jeweiligen Einlassöffnung (36) eine Abscheiderstruktur (39) zum Abscheiden von im Abgas mitgeführten Partikeln angeordnet ist. An improved protection against impurities is achieved if a separator structure (39) for separating particles entrained in the exhaust gas is arranged in or at the respective inlet opening (36).
