Abstract: An impact fuel system comprising an air chamber in communication with a fuel chamber, a rotatable fuel accelerator wheel interposed between the air chamber and fuel chamber, fuel passageway extending between a fuel supply and the central portion of the fuel accelerator wheel for directing fuel to the interior thereof, the fuel accelerator wheel being provided with outlet ports around the outer periphery thereof for ejecting fuel against an impact ring to break the fuel into small droplets, an air passageway provided around the outer periphery of the fuel accelerator wheel receives the air droplets at a void area in the air stream whereby highly vaporized fuel air mixture is delivered to an internal combustion engine or the like for fuel economy and reduction of pollutants in the exhaust gases of the engine.

Abstract: A centrifugal separator for a fluid stream and comprising a stationary outer housing having a drive drum assembly rotatably mounted therein, the drive drum assembly including multiple fluid compartments in successive downstream communication for successively receiving the fluid stream therein. The fluid stream is centrifuged in each of the fluid compartments whereby an efficiently separated fluid stream is discharged from the drive drum assembly for delivery to the ultimate use for the fluid stream.
