    摘要: Ion mobility spectrometer. The spectrometer includes an enclosure for receiving a sample therewithin and an electron beam window admits an electron beam into the enclosure to ionize the sample in an ionization region. A shutter grid is spaced apart from the ionization region and means are provided for sample ion preconcentration upstream of the shutter grid. The ion preconcentration is effective to reduce space charge resulting in a lowered threshold detection level.

    摘要: 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.

    摘要: A fuel tank system for gasoline or flexible gasoline/ethanol powered vehicles that use independently controlled direct ethanol injection to provide a large on-demand octane boost is disclosed. The on-demand octane boost is used when needed to prevent knock. The ethanol can be in the form of 100% ethanol or E85 (a 85% ethanol, 15% gasoline mixture) and is stored in a second tank that is separate from the tank that which contains the primary fuel. The primary fuel can be gasoline, E85, ethanol or a mix of these fuels. The fuel tank system enables convenient, quick, flexible and minimal cost refueling of the separate fuel tank. A range of fueling options is available to provide the driver with the maximum freedom to choose fuels depending upon price and availability. Valves may be utilized to direct the flow in fuel to the various tanks.
