A mixing arrangement for an exhaust-gas system of an internal combustion engine for mixing exhaust gas and reactant includes an exhaust-gas guiding component which delimits an exhaust-gas flow volume and which extends in the direction of a longitudinal axis, a reactant dispensing unit for dispensing reactant into the exhaust-gas flow volume, downstream of the reactant dispensing unit an exhaust-gas flow volume dividing arrangement, the exhaust-gas flow volume dividing arrangement dividing the exhaust-gas flow volume in a dividing length region into a plurality of partial exhaust-gas flow volumes, the plurality of partial exhaust-gas flow volumes including a central partial exhaust-gas flow volume and at least one partial exhaust-gas flow volume which surrounds the central partial exhaust-gas flow volume in a ring-like manner.

Mixing arrangement for an exhaust-gas system of an internal combustion engine

A mixer for an exhaust system of an internal combustion engine for mixing exhaust gas and reactant includes a mixing chamber, a reactant dispensing arrangement for dispensing reactant into the mixing chamber axially between an upstream mixer wall and a downstream mixer wall, an inlet opening arrangement in the upstream mixer wall, an outlet opening arrangement in the downstream mixer wall, a flow guiding arrangement arranged between the upstream mixer wall and the downstream mixer wall, wherein the flow guiding arrangement provides a first flow path leading from the inlet opening arrangement to the outlet opening arrangement and a second flow path leading from the inlet opening arrangement to the outlet opening arrangement, wherein each flow path has at least two flow channels leading from the inlet opening arrangement to the outlet opening arrangement.

Mixer

A mixing subassembly for an exhaust gas system of an internal combustion engine for mixing exhaust gas, which is discharged by an internal combustion engine, with reactant includes a mixing path which extends in the direction of a mixing path longitudinal axis and which has an upstream mixing path inflow region for receiving exhaust gas and/or reactant in the mixing path. The mixing path includes a core flow channel, through which a first exhaust gas partial flow flows, and a bypass flow channel, through which a second exhaust gas partial flow flows. At least one flow blocking element reduces a flow cross section of the bypass flow channel and is arranged in the bypass flow channel.

Mixing subassembly for an exhaust gas system of an internal combustion engine

An exhaust gas/reactant mixing arrangement for an exhaust system of an internal combustion engine mixes exhaust gas and reactant. The mixing arrangement includes an exhaust gas guide housing defining a longitudinal axis and having a housing wall. An exhaust gas duct is surrounded by the housing wall and exhaust gas can flow therethrough. A mixing zone has a mixing chamber formed between an upstream end wall and a downstream end wall and a reactant dispensing arrangement is supported on the exhaust gas guide housing. The reactant dispensing arrangement dispenses reactant into the mixing chamber along a reactant dispensing line in a dispensing direction. A mixture flow path leads from an inflow opening to an outflow opening and is formed in the mixing chamber. The mixture flow path has two flow deflection regions, which follow one another in a mixture flow direction and have mutually opposite flow deflection directions.

Exhaust gas/reactant mixing device

A mixer assembly unit, for an exhaust system exhaust gas treatment unit of an internal combustion engine, mixes exhaust gas discharged by the internal combustion engine with reactant. A mixing section (), downstream in relation to a reactant release device (), mixes exhaust gas, flowing in an exhaust gas flow direction, with reactant. The mixing section includes a core flow duct (), extending in a direction of a mixing section longitudinal axis (L), through which a first exhaust gas partial stream (T) flows. A second exhaust gas partial stream (T) flows through a jacket flow duct () surrounding the core flow duct and separated from the core flow duct by an inner wall (). The reactant release device releases reactant into the core flow duct or/and into the first exhaust gas partial stream. A mixer () is provided at an upstream end area () of the mixing section.
