A carburetor atomizer including a cylindrical body with a central bore is disclosed. The body is arranged upstream of the venturi and throttle plate. The bore is oriented parallel to the flow axis of the carburetor. The body has one or more annular conduits circumferentially arranged around the bore, each conduit communicating with the bore through a respective plurality of circumferentially spaced ducts, which can be radially or tangentially oriented relatively to the bore. Respective feeder tubes supply at least one annular conduit with fuel which is drawn into the bore through the ducts where the fuel is broken-up into droplets and mixed with air flowing through the carburetor and bore. Metered air is injected into the bore through a second annular conduit and plurality of ducts which promotes further atomization of the fuel and mixing of the fuel-air mixture in the bore. A passageway is provided between the inlet end of the bore and the annular conduit wherein ram air causes a region of higher pressure to counteract fuel siphoning into the bore at engine idle speeds.
