  • Publication number: 20140000571
    Abstract: The present invention relates to a system and method for providing fuel to internal combustion engines including fuel activation prior to injection. The method carried out by the system comprises dissolving a mixture of gasses providing improved fuel dispersing after fuel injection into a combustion chamber. Dissolved gasses desorption is stimulated from a unsaturated fuel solution. Full control of fuel flows with dissolved gas/gasses to and from injectors and FET technology based on Henry's law (dissolving gasses in the liquids) and Kelvin principle (vapor pressure over droplet surface). The system consists of compact components, including exhaust gasses recirculation system which can be easily added to existing diesel and gasoline engine fuel supply systems. The method and system were tested with four different types of engines and provides fuel economy in 12-20% decrease of emissions and up to 25% at variable engine loads and significantly at engine cold start.

  • Publication number: 20130312699
    Abstract: Many IC engine inefficiencies are linked to the relatively low mixture formation rates of current injection methods. Process intensification (PI) is excellent at high mixture formation rates, high mass transfer rates, and short residence times, therefore a wall integrated injection method and device featuring PI has been provided. It allows increased number of injection sites and interfacial surface area between fluid jets and the volume of the squash area, hence high mixture formation rates shorter Liquid Lengths and the use of micro nozzles to further intensify the mixing process by locally mixing fuel and oxidant. This allows high EGR and low compression ratios and better control of HCCI start of ignition. PI effectively achieves thermo and species stratification for extending the load range of the HCCI engine while permitting effective water addition for reciprocating and turbine for lower exhaust heat and less fuel burned hence less CO2 emissions.

  • Patent number: 8555866
    Abstract: An injection gate (44,144,244,344) for high pressure, high velocity secondary fluid for admixture of an atomized spray (80,180) thereof with another or primary fluid that atomizes the other fluid. The secondary fluid may be an accelerant and the primary fluid may be a low pressure fuel/air mixture in a fuel injection arrangement for an internal combustion engine. An injection billet (10,110,210,310) for an engine is interposed between the carburetor (12) and the manifold (14), with an array of such injection gates (44,244,344) paired with an array of fuel/air gates (34,234,334) about an aperture coinciding with a throttle bore (60,160,260,360) and evenly balancing the spray about the throttle bore, creating a halo effect of atomized admixture of accelerant/fuel. The injection of accelerant is directed sharply downwardly toward the center of the bore and through the injected fuel stream, atomizing the fuel thereof for a high efficiency boost of horsepower.

  • Patent number: 8495990
    Abstract: A pre-injection fuel atomization system for a combustion engine that reduces droplet size of incoming fuel at air intake, creating an aerosol that is injected by fuel injectors into the combustion chambers. The system uses a vibrating crystal in a transducer, the vibrations atomizing the fuel into an aerosol. The droplet size is reduced to around 0.1 microns, providing more surface area available for fast surface combustion. The fuel droplets are maintained in a stoichiometric ratio to oxygen in the air so that burning is complete and clean.
