    摘要: A hydrogen enhanced engine system using high compression ratio is optimized to minimize NOx emissions, exhaust aftertreatment catalyst requirements, hydrogen requirements, engine efficiency and cost. In one mode of operation the engine is operated very lean (equivalence ratio φ=0.4 to 0.7) at lower levels of power. Very lean operation reduces NOx to very low levels. A control system is used to increase equivalence ratio at increased torque or power requirements while avoiding the knock that would be produced by high compression ratio operation. The increased equivalence ratio reduces the amount of hydrogen required to extend the lean limit in order to avoid misfire and increases torque and power. The engine may be naturally aspirated, turbocharged, or supercharged.

    摘要: Rotary power system. The system includes a source of hydrocarbon fuel which is supplied to a plasmatron which reforms the fuel into a hydrogen-rich gas. An internal combustion engine is connected to receive the hydrogen-rich gas from the plasmatron. The engine powers an electrical generator and the generated electricity is connected to the plasmatron. In one embodiment, the engine also receives hydrocarbon fuel along with the hydrogen rich gas. The combination of plasmatron and internal combustion engine results in lowered exhaust emissions.

    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.

    摘要: 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.

    摘要: 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.
