摘要： A static mixer for exhaust gas ducts of internal combustion engines includes an elongated hollow metal body having a shape which, relative to a symmetry axis, substantially corresponds to a solid of revolution defining at its inside a cavity having opposite bases, at least one of which has an axial opening, and a closed lateral wall connecting the opposite bases and having at least one radial opening over which a concave blade is arranged extending radially outward from a portion of the peripheral edge of the radial opening and surrounding a portion of the radial opening so as to define, in a first angular direction relative to the symmetry axis, a corresponding concave screen or spoon and, in a second, opposite direction, a mouth intended for the passage of gases and located substantially in front of the concave screen or spoon.

摘要： Unit for reduction of exhaust gases for an IC engine. The unit has a cylindrical housing with gas inlet and outlet openings and injector for a reducing substance. A helicoid is coaxially arranged inside the housing. A channel conveys the exhaust gases, has a substantially quadrangular cross-section, and helicoidally develops inside the unit. The helix is generated by the intersection between the inner surface of the housing and the helicoid has an inclination angle (β) relative to planes perpendicular to the generatrices of the cylindrical housing ranging from 0° to 30°. The unit includes a coaxial stiffening and stabilization sleeve located at the center of the helicoid passing axially throughout the helicoid and axially over a length at least equal to the axial length of the helicoid. The sleeve cooperates with the inner surface of the housing and with the opposite surfaces of the helicoid to define the helicoidal channel.

摘要： Multi-layered filter element (11) comprising at least two layers (13,15) of filtering material made of paper pleated in an accordion-like way along parallel bending lines, so as to define, along said bending lines, a series of ridges (13a, 15a) alternated with grooves (13b, 15b), the at least two layers (13,15) being undetachably held together in the filter element, except when the filter element itself becomes destroyed, by sealing gaskets (23,25) made of plastic material in which the paper of the layers (13,15) is partially incorporated, adjacent layers (13,15) of filtering material being arranged close to each other and the ridges (13a, 15a) of different layers being mutually parallel, wherein between adjacent layers (13,15) there are provided spacers (17) arranged on the paper ridges (13a, 15a) perpendicularly thereto, said spacers preventing the ridges (13a, 15a) of a layer (13,15) from penetrating into the grooves (13b, 15b) of the adjacent layer (13,15) and vice versa; the invention further relates to a method for making the filter element.
