Abstract

Die Erfindung gibt eine Mischvorrichtung (2) zur Nachbehandlung von Abgasen in einer Abgasanlage einer Brennkraftmaschine, die ein Gehäuse (4) mit einer einen Eintrittsquerschnitt aufweisenden Eintrittsöffnung (24) und ein innerhalb des Gehäuses (4) angeordnetes Innenrohr (6) mit einem im Inneren des Innenrohres (6) ausgebildeten Mischbereich (8) umfasst, wobei an einer Stirnseite des Gehäuses (4) eine Dosiereinrichtung (10) zur Zuführung einer Flüssigkeit und/oder eines Flüssigkeit-Gas-Gemisches (14) angeordnet ist, und wobei das Innenrohr (6) an seiner Mantelfläche (16) Zutrittsöffnungen (18) aufweist, durch welche die Abgase in den Mischbereich (8) einleitbar sind. Dabei weist das Gehäuse (4) einen spiralförmigen Gehäuseabschnitt (22) auf, wobei sich der spiralförmige Gehäuseabschnitt (22) zumindest entlang sämtlicher Zutrittsöffnungen (18) erstreckt. Ferner gibt die Erfindung ein Verfahren zum Mischen Abgases mit einer Flüssigkeit und/oder einem Flüssigkeit-Gas-Gemisches unter Verwendung einer vorgenannten Mischvorrichtung (2) an.
