  • Publication number: 20100063712
    Abstract: Engine management system for operation of a direct injection spark ignition gasoline engine. The system includes a gasoline engine, a source of gasoline and a source of an anti-knock agent. Gasoline and anti-knock agent are introduced into a proportioning valve that delivers a selected mixture of gasoline/anti-knock agent to a high pressure pump. At least one injector receives the selected mixture from the high pressure pump and delivers the mixture into a cylinder of the engine. The engine management system provides a rapidly variable mixture of directly injected anti-knock agent and gasoline which prevents knock as the engine torque increases.

  • Patent number: 7656258
    Abstract: A magnet structure for particle acceleration includes at least two coils that include a continuous path of superconducting material [e.g., niobium tin (Nb3Sn) having an A15-type crystal structure] for electric current flow there through. The coils can be mounted in a bobbin, which together with the coils form a cold-mass structure. The coils are cooled to their superconducting temperatures via cryocoolers. Radial-tension members are coupled with the cold-mass structure to keep it centered, such that it remains substantially symmetrical about a central axis and is not pulled out of alignment by magnetic forces acting thereon. A wire can be wrapped around the coils, and a voltage can be applied thereto to quench the coils to prevent their operation of the coils in a partially superconducting condition, which may otherwise cause damage thereto. A magnetic yoke surrounds the cold-mass structure and includes a pair of poles that, in part, define an acceleration chamber there between.

  • Publication number: 20100022669
    Abstract: The present invention includes a method for converting renewable energy source electricity and a hydrocarbon feedstock into a liquid fuel by providing a source of renewable electrical energy in communication with a synthesis gas generation unit and an air separation unit. Oxygen from the air separation unit and a hydrocarbon feedstock is provided to the synthesis gas generation unit, thereby causing partial oxidation reactions in the synthesis gas generation unit in a process that converts the hydrocarbon feedstock into synthesis gas. The synthesis gas is then converted into a liquid fuel.

  • Publication number: 20100006050
    Abstract: Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.

  • Patent number: 7640913
    Abstract: Fuel management system for operation of a spark ignition engine. The system includes a source of gasoline and a source of anti-knock fuel. A proportioning valve receives the gasoline and the anti-knock fuel to discharge a mixture having a controlled gasoline/anti-knock fuel ratio. A single high pressure pump receives the mixture and delivers the mixture to an injector. A fuel management control system controls the proportioning valve and the injector for injection of the mixture into a cylinder of the engine to control knock. A preferred anti-knock fuel is ethanol.

  • Patent number: 7640915
    Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

  • Patent number: 7637250
    Abstract: Fuel management system for operation of a spark ignition gasoline engine. The system includes a gasoline engine powering the vehicle and a source of gasoline for introduction into the engine. A source of an anti-knock fuel such as ethanol is provided. An injector directly injects the anti-knock fuel into a cylinder of the engine and the control system shuts down the engine by stopping gasoline and anti-knock agent flow into the engine during vehicle deceleration and idling and restarts the engine upon driver demand. Direct ethanol injection and engine shutdown results in efficiencies similar to those of full hybrid vehicles.

  • Publication number: 20090260350
    Abstract: Regeneration system in which a hydrogen-rich gas from an onboard reformer flows into an aftertreatment unit in a direction opposite to the flow of engine exhaust to regenerate the unit. The aftertreatment unit is segmented with independent regeneration capability for each segment. Regeneration is performed with hydrogen-rich gas produced by an onboard reformer. A hydrogen-rich gas switchbox is used to direct the flow of the reformate to the segment of the aftertreatment unit that is undergoing regeneration.

  • Patent number: 7597860
    Abstract: A novel apparatus and method is disclosed for a plasmatron fuel converter (“plasmatron”) that efficiently uses electrical energy to produce hydrogen rich gas. The volume and shape of the plasma discharge is controlled by a fluid flow established in a plasma discharge volume. A plasmatron according to this invention produces a substantially large effective plasma discharge volume allowing for substantially greater volumetric efficiency in the initiation of chemical reactions within a volume of bulk fluid reactant flowing through the plasmatron.

  • Publication number: 20080210861
    Abstract: The present invention describes apparatuses and methods that provide energy to ions in a non-thermal manner. The elevated ion energy minimizes or eliminates interferences due to clustering with polar molecules, such as water. The energized ions are separated in an ion mobility spectrometer. During the ion transportation and separation process, the elevated energy level of ions prevents them from clustering with neutral molecule inside the spectrometer. The additional electric field component only causes ions to reach elevated energy level, whereby the spectrometer can preserve its normal performance, meanwhile avoiding interference from water and other neutral molecules. A RF electric field is applied to the ions in ionization, reaction and separation region of ion mobility spectrometers.

  • Patent number: 7407634
    Abstract: A novel apparatus and method is disclosed for a plasmatron fuel converter (“plasmatron”) that efficiently uses electrical energy to produce hydrogen rich gas. The plasmatron has multiple decoupled gas flow apertures or channels for performing multiple functions including fuel atomization, wall protection, plasma shaping, and downstream mixing. In one aspect, the invention is a plasmatron fuel converter comprising a first electrode and a second electrode separated from the first electrode by an electrical insulator and disposed to create a gap with respect to the first electrode so as to form a discharge region adapted to receive a reactive mixture. A power supply is connected to the first and second electrodes and adapted to provide voltage and current sufficient to generate a plasma discharge within the discharge region. Fluid flows are established in the vicinity of the plasma discharge region by multiple decoupled flow establishing means.

  • Publication number: 20080169417
    Abstract: Ion mobility spectrometer. The spectrometer includes an enclosed region having a gas with a selected chemical species contained therein. An energy source ionizes the gas and the chemical species. Spaced apart electrodes generate high frequency and DC electric fields across the enclosed region and circuitry is provided for generating voltage waveforms on the electrodes. The voltage waveforms include a symmetric RF field to minimize ion loss and to prevent clustering of the ions with water molecules during an ion buildup phase. A DC and asymmetric, non-uniform RF field is provided to separate and focus the ions in the region during an ion separation phase. Finally, a changing DC or RF field causes the ionized chemical species to move to the electrodes and read-out circuitry responds to current in the electrodes to indicate the presence and/or amount of the chemical species.
