Abstract

An internal combustion engine exhaust system mixer device includes a bottom element (12) includes a downstream rear side (22) and a front side (44). The bottom element has a reactant introduction opening (31), open to a reactant receiving volume (46), and expands therefrom radially from the reactant introduction opening toward the front side. Exhaust gas passage ducts (58), arranged following one another in the circumferential direction about the opening axis (A), open to the reactant receiving volume. A swirl generation element (20) is connected to the bottom element and encloses the opening axis. A mixing volume (64) adjoins the reactant receiving volume in the direction of the opening axis and is formed in the swirl generation element. A plurality of exhaust gas passage openings (66), following one another in the circumferential direction, about the opening axis are provided in the swirl generation element.
