Reducing agent i.e. aqueous urea solution, inserting component for use in exhaust gas line, has device provided for producing gas flow that flows over wall of supply nozzle additional to reducing agent flow

摘要

#CMT# #/CMT# The component has a supply nozzle (14), which discharges in an exhaust gas line (12) and a supply device (20) i.e. low pressure fuel injecting valve, for a reducing agent e.g. aqueous urea solution, which discharges in the nozzle. A device (22) is provided for producing a gas flow (G) that flows over a wall (16) of the nozzle additional to a reducing agent flow. The device has an inlet port (24) for the gas flow (G) arranged in the wall of the nozzle and designed in an orifice area of the nozzle in the line. #CMT#USE : #/CMT# Component for insertion of a reducing agent i.e. aqueous urea solution (claimed), into an exhaust gas line of an exhaust system of an internal combustion engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The component is designed in such a manner that the reducing agent i.e. aqueous urea solution, is inserted into the exhaust gas line of an exhaust system of an internal combustion engine of a motor vehicle, in such a manner that urea deposition is avoided or strongly reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a component.
