FIELD: engines and pumps.
SUBSTANCE: invention relates to automotive industry. Dispensing module (1) dispenses this reducing agent to the flow of exhaust gases generated by ICE and directed to postprocessing system (30). Dispensing module (1) comprises case (20), inlet (9) for transfer of exhaust gas flow to dispensing module case (20) and means (55) for dosed feed of urea-based reducing agent. Case (20) extends symmetrically in axis (X) while inlet (9) is axially symmetric circular and inclined relative to said axis (X) of dispensing module for development of inclined axially symmetric circular inlet jet (AJ). Said means (55) develops urea-based reducing agent jet (UWS) inside case (20).
EFFECT: better mixing of reducing agent with exhaust gas flow, higher efficiency of postprocessing catalyst.
