Abstract

An exhaust gas/reactant mixing arrangement is for an exhaust system of an internal combustion engine for mixing exhaust gas and reactant. The mixing arrangement includes an exhaust gas guide housing extending in the direction of a housing longitudinal axis and a housing wall. The housing wall surrounds and defines an exhaust gas duct accommodating a flow of exhaust gas. A mixing zone is formed between an upstream end wall and a downstream end wall arranged downstream of the upstream end wall. The mixing zone includes a first chamber and a second chamber as well as a reactant dispensing unit carried on the exhaust gas guide housing for dispensing reactant into the first chamber in a reactant main dispensing direction oriented substantially along a reactant dispensing line.
