Abstract: A method for reducing required octane number and a spark ignition gasoline engine system with hydrogen-enhanced knock resistance. The method for reducing required octane number of gasoline needed to prevent knock includes the addition of hydrogen or hydrogen-rich gas containing carbon monoxide to gasoline. Octane number can be improved by 5 or more for a hydrogen energy fraction of 10%. The spark ignition gasoline engine system includes a spark ignition gasoline engine and a source of gasoline and hydrogen or hydrogen-rich gas. Apparatus is provided to supply the gasoline and the hydrogen or hydrogen-rich gas to the engine at a varying hydrogen or hydrogen-rich gas to gasoline ratio selected both to prevent knock and to ensure a desired level of combustion stability throughout a full range of engine operation. The engine system may be normally aspirated or boosted; the compression ratio may be high such as greater than 11 or below 11, and EGR may be added. The hydrogen or hydrogen-rich gas to gasoline ratio may be controlled as a function of boost pressure, torque, engine speed, or air/fuel mixture ratio.

Abstract: The singlet delta energy levels of molecular oxygen (SDO) are generated to enhance the performance of internal-combustion engines, diesel engines in particular. In the preferred embodiments, this control takes place just prior to, and in the initial stages of, fuel injection. The SDO can be generated using different methods according to the invention, including thermal means, optical/laser energy, electrical/electromagnetic excitation, or a combination of these approaches. SDO may also be generated through reactions of a chemical fuel additive or a laser-excited chemical additive. A system for improving the performance of an internal combustion engine according to the invention includes a source or energy operative to generate singlet delta oxygen (SDO) from molecular oxygen, and apparatus for mixing the SDO with fuel prior to, or during, combustion. In the preferred embodiment, the SDO is delivered with air through an air-intake port, and a laser is used in a multi-pass absorption cell.

Abstract: A system for conditioning intake air for an internal combustion engine includes an oxygen separation system. The oxygen separation system includes an entry port for ambient air, and at least two separate exhaust ports through which separate exhaust streams are drawn by separate suction sources. The oxygen separation system further includes a plurality of gas-permeable electrodes that are charged to provide a high-voltage static electric field inside the separator. An exhaust stream taken from the anode side of the separator is enriched in oxygen relative to ambient air. This oxygen-enriched stream is provided to an internal combustion engine for use in combusting fuel.
