Mixer

An exhaust system for an internal combustion engine, the exhaust system comprising:

• a mixer housing;
• a first exhaust gas-carrying conduit adjoining the mixer housing in an upstream end area of the mixer housing;
• a second exhaust gas-carrying conduit adjoining the mixer housing in a downstream end area of the mixer housing;
• a mixer arranged in a mixer carrying area of the mixer housing, wherein the mixer is arranged with an incoming flow side facing the first exhaust gas-carrying conduit, the mixer comprising:
• a plate-shaped mixer body with an incoming flow side arranged oriented in an upstream direction in relation to an exhaust gas flow directed in an exhaust gas principal flow direction in the first exhaust gas-carrying conduit and with an outflow side to be arranged oriented in a downstream direction in relation to the exhaust gas flow;
• a first exhaust gas flow-through opening in the mixer body, wherein the first exhaust gas flow-through opening is configured so as to be elongated in a direction of a first exhaust gas flow-through opening longitudinal axis extending essentially at right angles to the exhaust gas principal flow direction;
• a reactant-receiving body carried on the mixer body in an area of the first exhaust gas flow-through opening, wherein the reactant-receiving body defines a reactant-receiving body flow-through duct, through which exhaust gas can flow, and wherein the reactant-receiving body has a V-shaped reactant-receiving area tapering in a direction of the first exhaust gas flow-through opening longitudinal axis;
• and
• a plurality of second exhaust gas flow-through openings in the mixer body, wherein the second exhaust gas flow-through openings are arranged surrounding the first exhaust gas flow-through opening in the mixer body;
• and
• a reactant release device arranged downstream in relation to the mixer body at the mixer housing, for a release of reactant with a reactant principal direction of release directed toward the reactant-receiving body;
• wherein, in association with at least one second exhaust gas flow-through opening, the mixer body comprises a bulge, which protrudes on the outflow side and is open on a side facing the first exhaust gas flow-through opening.

A mixer for an exhaust system of an internal combustion engine, the mixer comprising:

• a plate-shaped mixer body with an incoming flow side to be arranged oriented in an upstream direction in relation to an exhaust gas flow directed in an exhaust gas principal flow direction, and with an outflow side to be arranged oriented in a downstream direction in relation to the exhaust gas flow;
• a first exhaust gas flow-through opening in the mixer body, wherein the first exhaust gas flow-through opening is configured so as to be elongated in a direction of a first exhaust gas flow-through opening longitudinal axis extending essentially at right angles to the exhaust gas principal flow direction;
• a reactant-receiving body carried on the mixer body in an area of the first exhaust gas flow-through opening, wherein the reactant-receiving body defines a reactant-receiving body flow-through duct, through which exhaust gas can flow, and wherein the reactant-receiving body has a V-shaped reactant-receiving area tapering in a direction of the first exhaust gas flow-through opening longitudinal axis;
• a plurality of second exhaust gas flow-through openings in the mixer body, wherein the second exhaust gas flow-through openings are arranged surrounding the first exhaust gas flow-through opening in the mixer body;
• wherein the reactant-receiving body comprises two mounting plate sections arranged bent at an angle to one another in the reactant-receiving area, at least one reactant passage opening, which is open toward the reactant-receiving body flow-through duct, being provided in at least one of the mounting plate sections;
• and
• wherein the reactant-receiving body has a central area with an essentially ring segment configuration enclosing the reactant-receiving body flow-through duct in some areas, the mounting plate sections extending toward one another, essentially uncurved, starting from the central area.
