Abstract
The present invention relates to a dosing module () for dosing an urea-based reducing agent into a exhaust gas stream of combustion engine and addressed to an after-treatment system, () e.g. SCR or SCRT system. The module () comprises an housing () which develops along a longitudinal axis (X) and an inlet opening () for conveying the exhaust gas. Dosage means () are provided for dosing the reducing agent. According to the invention, the inlet opening is annular and inclined with respect to the axis (X) of the housing () so as to generate an exhaust gas inlet jet (AJ). Moreover the dosage means are designed so as to generate, inside the housing (), an urea-based reducing agent spray (UWS) coaxial to the axis (X) of the housing ().
