    摘要： A reactant introduction device, for introducing reactant into an exhaust gas stream of an internal combustion engine, includes a reactant introduction housing (16) with a reactant introduction space (20) surrounded by a housing wall (18). The housing wall (18) includes an incoming flow wall area (30) positioned upstream in relation to an exhaust gas flow direction (A), an outgoing flow wall area (32) positioned downstream, in relation to the exhaust gas flow direction (A) and two side wall areas (34, 36) between the incoming flow wall area (30) and the outgoing flow wall area (32). At least one flow-through opening (72, 74, 76) is provided in at least one side wall area (34, 36) or/and in the outgoing flow wall area (32). A reactant injection device (28) injects reactant into the reactant introduction space (20) in a reactant introduction direction (E) onto a heatable reactant release element (48).
