    Abstract: Unit (11) for feeding a reducing solution from the tank to the exhaust duct of an endothemiic engine is provided. The unit comprises a supporting head (13) arranged for being associated to an aperture provided in a reducing solution tank and a heating device (15) for heating the reducing solution contained in the tank. The heating device (15) extends from the supporting head (13) and is provided with a duct (17) for a heating fluid. The duct (17) is defined by a side wall (31) which, when the unit (11) is in use, is internally in contact with the heating fluid passing through the duct (17) and externally in contact with the reducing solution present in the tank. At least one portion of the wall (31) of the duct (17) is non-smooth inside and/or outside the duct.

    Abstract: Dynamic mixer (11) with movable vanes (19) for exhaust gases of I.C. engines, comprising a stationary annular part (13) adapted to be connected to an exhaust gases duct of I.C. engines and a movable part (17) provided with a plurality of vanes (19), characterized in that the vanes (19) are disengaged from the stationary part (13) and have their roots associated to the movable part (17) so that the relative movement between the two parts (13,17) of the mixer causes a variation in the geometry of the vanes (19) with respect to the flow of exhaust gases that hits the mixer, while maintaining substantially constant form of the vanes.
