Abstract: The present invention refers to a method of using lean fuel-air mixtures at all operating regimes of a spark ignition engine, which is provided with an intake port fuel injection system, wherein said method is characterized in that in order to achieve the efficient lean mixture combustion process, an HHO oxy-hydric gas direct injection should be at a minimum pressure of 10 bar, during compression stroke, after intake valve closing, so that the hydrogen/fuel mixture volumetric fractions value is within the range of about 15% to 25%.

Abstract: A method of improving the efficiency of continuous water electrolysis processes to produce a hydrogen rich gas. Improved efficiency is realized by minimizing and/or eliminating wasted current, current that does not convert water to a hydrogen rich gas, attaining approximately 100% Faradic efficiency. This improvement in current or Faradic efficiency is attained by electrically isolating the electrolyte solution contained in each electrolysis cell as well as electrically isolating the electrolyte solution contained in each cell from the supply of electrolyte solution. This invention also improves the efficiency of water electrolysis processes through the utilization of electrodes coated with electrode specific nanomaterials, improving voltage efficiency at current densities exceeding 100 mA/cm2. Overall efficiency improvements of about 20% have been obtained with the present invention over other hydrogen rich gas generators.

Abstract: A method for improving the efficiency, enhancing the heat output, and reducing the harmful emissions of a solid carbonaceous fuel combustion system by introducing a hydrogen-rich gas into a solid carbonaceous fuel combustion process at one or more predetermined injection points or directly into a flame of the combustion process where the hydrogen-rich gas is controlled to be introduced at a desired flow-rate. The gas is introduced through one or more predetermined injection points which are selected from one or a combination of one or more primary air streams with the solid carbonaceous fuel prior to combustion, one or more secondary air streams with the solid carbonaceous fuel at combustion, one or more tertiary/overfire air streams downstream of the solid carbonaceous fuel combustion, and one or more injection ports near an exit end of a furnace of said combustion process.

Abstract: An electrolyzer with principal and supplemental electrodes configured and made from materials, which decomposes distilled water into a highly efficient clean burning fuel composed of hydrogen, oxygen and their bonds, called HHO or hydrogen-enriched gas that can be used as an additive to combustion engine fuels or in flame or other generating equipment such as torches and welders.

Abstract: The present invention discloses an electrolyzer for electrolyzing water into a gaseous mixture comprising hydrogen gas and oxygen gas. The electrolyzer is adapted to deliver this gaseous mixture to the fuel system of an internal combustion engine. The electrolyzer of the present invention comprises one or more supplemental electrode at least partially immersed in an aqueous electrolyte solution interposed between two principle electrodes. The gaseous mixture is generated by applying an electrical potential between the two principal electrodes. The electrolyzer further includes a gas reservoir region for collecting the generated gaseous mixture. The present invention further discloses a method of utilizing the electrolyzer in conjunction with the fuel system of an internal combustion engine to improve the efficiency of said internal combustion engine.
