Abstract

Die vorliegende Erfindung betrifft eine Abgasrückführeinrichtung (6) für eine Brennkraftmaschine (1), insbesondere in einem Kraftfahrzeug. Die Abgasrückführeinrichtung (6) umfasst eine Rückführleitung (7) sowie einen Frischgasleitungsabschnitt (8), in dem in einem Einleitungsbereich (9) eine Venturidüse (10) ausgebildet ist. Dabei mündet die Rückführleitung (7) in einem Niederdruckbereich (11) der Venturidüse (10) in den Frischgasleitungsabschnitt (8) ein.
Um eine Abgasrückführung in einem möglichst großen Betriebsbereich der Brennkraftmaschine (1) zu ermöglichen, weist die Venturidüse (10) einen variablen Durchströmungsquerschnitt auf.
