A device for use between the carburetor and intake manifold of an internal combustion engine, to produce a highly turbulent flow condition in fuel/air mixture, thereby causing better mixing and homogenization of the fuel and air, and breakup of the minute fuel droplets into even finer droplets. The device has a narrow outer conical ring contiguous to the inner surface of the manifold throat, with sides converging in the downstream direction. Helically twisted fins extend downwardly and radially inward from the outer ring, and are attached to a smaller-diameter inner conical ring located in the center of the manifold throat. Adjacent the inner ring, the fins are enlarged to form blades that are curved to impart a gyratory movement to part of the fuel/air mixture, while part of the mixture passes straight through the device without being given a gyratory motion. The gyrating and non-gyrating portions of fuel/air mixture intermix below the device to form a highly turbulent flow that breaks up the liquid droplets of fuel and produces intimate mixing and homogenization of the fuel and air.
A device for post-atomization of fuel/air mixture delivered by a carburetor through an intake manifold to the cylinder of an internal combustion engine, said device including a flange mounted between the carburetor and the intake manifold, said flange forming a conical ring contiguous with the inner surface of the manifold throat, a plurality of fins attached at their outer ends to said conical ring and extending radially inward toward the center of the manifold throat, and in the downstream direction with respect to the flow of the fuel/air mixture, a circular nozzle at the center of the manifold throat and below said conical ring, said nozzle having a central opening, said fins at their inner ends being enlarged and curved to form blades that join said nozzle tangentially with respect to said opening, and said blades for the most part extending radially outward toward the wall of the intake manifold.
