Patent ID: 8082732

Claim:
A device for admixing a reducing agent into an exhaust gas flow of an internal combustion engine having an exhaust system, the device comprising: a dosing device for feeding the reducing agent into the exhaust system; a hollow body operatively arranged on the exhaust system and having an internal volume coupled to the exhaust system in order to conduct exhaust gas, the dosing device being operatively configured in or on the hollow body; at least one heating rib heatable by the exhaust gas, the at least one heating rib being operatively configured downstream from the dosing device in the exhaust system and being substantially oriented such that a longitudinal axis thereof extends in a flow direction of the exhaust gas; and at least one additional heating rib oriented largely parallel to the one heating rib, wherein the at least one heating rib and the at least one additional heating rib are thin plates, each plate having substantially no cross-sectional area and at least two broad plate surfaces aligned parallel to the exhaust gas flow direction so as to minimize resistance to the exhaust gas flow.
