摘要： Device for improving the purifying liquid evaporation in an axially symmetric dosing module for an SCR device. The dosing module is able to dose a urea-based reducing agent into a gas exhaust stream generated by a combustion engine. The dosing module comprises a housing developing symmetrically along a development axis; a nozzle for dosing the urea-based reducing agent, arranged along said development axis; and an inlet opening for conveying the gas exhaust stream into the dosing housing, arranged annularly with respect to the nozzle. The device further includes a splitting wall, arranged within the inlet opening for defining at least two separate annular gas stream paths, one annular and coaxial with respect to another, one of them shaped for inducing a different axial speed into a respective gas stream with respect to another.
