Abstract
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.
