| 20100018507 | FUEL INTAKE FOR AN ENGINE - The two-stroke engine fuel intake connects a carburator with the intake port of a two-stroke engine, to homogenize substantially all of the fuel droplets in the fuel-air mixture. The intake tube is in thermal contact with the engine and uses the engine heat to heat the fuel-air mixture. Preferably an oil injection tube extends through the fuel intake tube and injects oil into the fuel-air mixture, heat from which vaporizes substantially all of the fuel-air mixture and assists with vaporizing the oil into the fuel-air mixture. | 01-28-2010 |

| 20120138024 | Coolant-to-Catalyst Fuel Modification Method and Apparatus - A catalytic apparatus for efficient pre-combustion refinement of fossil fuel in vehicular engines, including an elongated outer metal pipe containing an elongated stainless steel inner tube of smaller diameter. The outer pipe is crimped or welded onto the inner tube to create a fuel chamber with connectors for the inflow and outflow of fossil fuel therethrough. The fuel chamber contains at least three catalytic elements each comprised of a different metal selected from the group Au, Cu, Ir, Ni, Pd, Pt, Zn and platiniridium, which may be electroplated small-pore screens. As engine coolant is diverted through the inner tube, excess heat is transferred to the inflowing fuel. The fuel is forced to flow in close proximity to the inner tube for maximum convection, and through the catalytic elements before flowing out through the fuel line to the fuel injectors for more efficient combustion. | 06-07-2012 |

| 20080230039 | Continuous liquid fuel vaporizer - A tubular vaporizer for vaporizing volatile liquids, and especially hydrocarbon fuels. Liquid fuel is passed into the vaporizer tube, is vaporized by heat transferred through fuel contact with the hot walls, and vaporized fuel exits the vaporizer tube. A hot carrier air stream is passed through the vaporizer with the vaporized fuel, greatly reducing the rate of buildup of deposits on the vaporizer walls; however, fueling of the vaporizer eventually must be shut down to remove the deposits. The deposits are easily removed, and the vaporizer tube completely regenerated, by passing hot air alone through the tube for a period of time. In a preferred embodiment, two parallel-path vaporization tubes and switching means therebetween are provided for alternate use and regeneration cycles, affording a continuous flow of vaporized fuel from the apparatus. The vaporizer is especially useful in providing gaseous fuel for a catalytic hydrocarbon reformer. | 09-25-2008 |
