An elongated upstanding bearing block is provided and rotatably supports a bladed axial flow impeller from the upper end thereof with the axis of rotation of the impeller extending longitudinally of the bearing block. A pair of support arms are carried by and spaced about the block and include upper end portions outwardly displaced from corresponding peripheral portions of the block. The upper ends of the support arms are secured to peripherally spaced portions of a split expansion ring at points spaced from overlapped ends of the ring and a generally cylindrical screen body is disposed about the bearing block in spaced relation thereto and about the support arms and the split ring with the upper end of the cylindrical screen body being placed under expansive tension by means of the expansion ring, the upper end of the screen body being positionable within the inlet port of an intake manifold and retained therein by the expansive forces acting upon the upper end of the screen body by the split expansion ring. Further, a heat coil is spiralled about the bearing block spaced inwardly of the screen body and outwardly of the block and the opposite ends of the coil extend downwardly below the bearing block and the lower end of the screen body for projection into an underlying exhaust passage.

In combination an internal combustion engine including an intake manifold of the type including a main passage extending therethrough and an inlet port opening transversely into said passage intermediate its opposite ends, a fuel atomizing device comprising a central elongated bearing block, a rotary bladed axial impeller journaled from and outwardly of one end of said block, a cylindrical screen body substantially concentrically disposed about said block and said impeller in spaced relation thereto and with the latter spaced inwardly of one inlet end of saId body, and mounting means stationarily supporting said block in position within said body and the latter from said manifold with said inlet end of said screen body disposed within the inlet port of said manifold and the remainder of said screen body extending substantially fully transversely across the central passage of the manifold into which said inlet port opens, said mounting means including a pair of opposite side elongated arms supported from said block and having one pair of ends thereof projecting endwise outwardly of said one end of said block, a split expansion ring disposed outwardly of said one end of said block and to peripherally spaced portions thereof said one pair of arm ends are secured, said expansion ring being expanded in said inlet end of said body and thereby expanding said inlet end of said screen body into seated position within said port.
