  • Patent number: 10018109
    Abstract: The present invention directly affects two primary limitations of diesel fuel: poor vaporization and ease of auto-ignition. Superheated fuel is injected within a cone of steam. As a result, fuel is fully vaporized and steam controls ignition by momentarily isolating fuel from air. In order to achieve high vapor velocities, the present invention uses momentum of circulating fuel and water to propel them through the injector. Momentum is preserved by transfer valves that transfer moving liquids between through paths and injection paths. Momentum is further preserved by an injector design that minimizes turbulence that would absorb energy and reduce injected velocity. The fuel and water may be superheated before injection to convert to steam and vapor upon the release of pressure when injected into the combustion chamber. The injector may also be used to achieve high injection velocity for liquid fuel injection without heating.

  • Publication number: 20170241379
    Abstract: The present invention provides systems, methods and apparatus to overcome limitations of liquid fuel engine combustion. Liquid fuel is mixed with superheated water which vaporizes, mixes with air and ignites within the injector nozzle. The injector nozzles then accelerate the mixture into the engine combustion chamber where unburned fuel vapor mixes and burns. Combustion begins the instant of injection and increases uniformly. Combustion pressure builds progressively. Combustion of fuel vapor is more ideal, and better controlled. As part of the system and apparatus, the present disclosure also includes a low-cost high-speed solenoid valve which produces shorter injection pulses. It also includes a high-speed, high-air-volume solenoid fuel valve. In addition, the present invention and its disclosure create tools to develop and optimize this new method of fuel vapor injection.

  • Patent number: 7350514
    Abstract: The vaporizing liquid fuel system converts virtually all of the liquid passing through it to a vapor state for chemical or physical processes in the vapor state. One chemical process is combustion in an engine or fuel burning apparatus such as a heating device. The evaporator is comprised of a vapor chamber enclosed by a tube having liquid inlet and vapor outlet ports. The vapor chamber is virtually filled with a thermally conductive vaporizing surface. In the preferred embodiment the thermally conductive vaporizing surface is bonded to the inner surface of the tube. Heat is applied to the other surface and is conducted into the thermally conductive vaporizing surface where vaporization occurs. Heat may be supplied by a resistive film heater bonded to the outer surface of the tube, by heat conducted from a fuel burning system, by heat carried by fluid circulated from a fuel burning system.

  • Patent number: 6739846
    Abstract: A fluid moving system is disclosed wherein a plurality of stacked blowers may provide for the redundant supply of cooling fluid such as air. This system may be advantageously utilized to cool electronic equipment or other uses. One or more of the blowers may utilize an impellor design that allows for the axial flow of fluid through the blower in addition to a transverse fluid outlet. In addition, the blowers may incorporate a flow gate operative to reduce back flow should a particular blower have a reduced fluid flow.
