Abstract

Mischvorrichtung (1) zur Nachbehandlung von Abgasen (2) in einer Abgasanlage einer Brennkraftmaschine, die ein einen Eintrittsquerschnitt (3) aufweisendes Gehäuse (4) und ein innerhalb des Gehäuses (4) angeordnetes, sich im Wesentlichen parallel zu einer Hauptinjektionsrichtung (5) einer Dosiereinrichtung (6) zur Zuführung einer Flüssigkeit und/oder eines Flüssigkeit-Gas-Gemisches erstreckendes Innenrohr (7) mit einem im Inneren (8) des Innenrohres (7) ausgebildeten Vormischbereichs (10) umfasst, wobei das Gehäuse (4) einen spiralförmigen Gehäuseabschnitt (13) aufweist und an einer Stirnseite (11) des Gehäuses (4) die Dosiereinrichtung (6) angeordnet ist, wobei ein Abgashauptstrom (12) zwischen dem Gehäuse (4) und der äußeren Mantelfläche (14) des Innenrohres (7) geführt und einem Hauptmischbereich (16) zuführbar ist und ein Abgasteilstrom (17) durch einen Innenrohrdurchtritt (18) in den dosiereinrichtungsnäheren Vormischbereich (10) zuführbar ist, wobei der Abgasteilstrom (17) über den Vormischbereich (10) in den Hauptmischbereich (16) mündet und der Abgashauptstrom (12) einen größeren Abgasvolumenanteil als der Abgasteilstrom (17) umfasst.
