A mixer device for an exhaust system of an internal combustion engine includes a tubular carrier () enclosing a mixer longitudinal axis (A) in a ring shape configuration and a mixer insert () carried at the carrier (). The mixer insert () has a plurality of connection attachments () located at spaced locations from one another in relation to the mixer longitudinal axis (A) radially on the outside. The carrier () has a plurality of connection recesses () for the permanent connection of the mixer insert () to the carrier ().

Mixer device

A mixer for an exhaust system of an internal combustion engine includes a first mixer part () with a plate shape body () having an incoming upstream flow side (), with respect to an exhaust gas main flow direction (A) and a downstream outflow side (), and a second mixer part (), on an outflow side, with a bottom wall () spaced apart from the plate shape body and with two side walls (), extending from the bottom wall () towards the plate shape body and fixed at the first mixer part. The mixer parts define a reactant injection duct () receiving reactant in a main injection direction (R). An exhaust gas main passage opening () the plate shape body opens towards the reactant injection duct with a plurality of exhaust gas secondary passage openings () run past the injection duct.

Mixer

A mixer for an exhaust system for mixing reactant injected into an exhaust gas stream with exhaust gas includes a mixer body (). The mixer body includes a reactant passage body area () with a reactant passage opening (), a mixer plate body area () adjoining the reactant passage body area () on one side in a mixer longitudinal direction (L) and a mixer main body area () adjoining the reactant passage body area () in the mixer longitudinal direction (L) on another side opposite the one side.

Mixer for an exhaust system comprising two oppositely bent areas

An exhaust system for an internal combustion engine includes an oxidation catalytic converter unit () with a first catalytic converter housing with a first housing axis (A). An SCR catalytic converter unit () has a second catalytic converter housing (), with a second housing axis (A). A mixer housing () has an upstream connection area () adjoining a downstream end () of the first catalytic converter housing () and has a downstream connection area () adjoining an upstream end () of the second catalytic converter housing. A mixer () is carried in the mixer housing. A reactant release device () at the mixer housing releases reactant into a reactant-receiving duct () of the mixer. The mixer housing includes a first housing part () forming the upstream connection area () and a second housing part () forming the downstream connection area together with the first housing part.

Exhaust system

A mixer for an exhaust system of an internal combustion engine includes a plate-shaped mixer body () with an incoming flow side () to be arranged oriented in the upstream direction in relation to an exhaust gas flow (H) and with an outflow side () to be arranged oriented in the downstream direction in relation to the exhaust gas flow (H), a first exhaust gas flow-through opening () in the mixer body (), a reactant-receiving body () carried on the mixer body () in the area of the first exhaust gas flow-through opening (), as well as a plurality of second exhaust gas flow-through openings () in the mixer body (). The second exhaust gas flow-through openings () are arranged surrounding the first exhaust gas flow-through opening () in the mixer body ().

An exhaust system, especially for an internal combustion engine of a vehicle, includes an exhaust gas-carrying duct () and a reactant injection device () for injecting reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying duct (). Downstream of the reactant injection device (), a mixer device () supports the mixing of reactant (R) injected by the reactant injection device () with exhaust gas (A) flowing in the exhaust gas-carrying duct (). Downstream of the reactant injection device () and upstream of the mixer device (), a reactant heating device () extends in the exhaust gas-carrying duct (). The exhaust gas (A) flows in and reactant (R) injected through the reactant injection device () flow around the heating device ().
