    摘要: A fuel injection system is disclosed having a fuel injection nozzle which receives pressurized fuel pulses from a source. The nozzle includes a body having a tubular nozzle body with a longitudinally extending opening extending therethrough. A valve seat is located between the upstream and downstream ends of the longitudinal opening in the valve body for engagement with a valve member to thereby regulate the flow of fuel through the opening. A downstream stop member includes a hollow cylinder with a diametrical member extending across one end. The cylindrical stop member is received over the downstream end of the nozzle body with the diametrically extending member disposed across the downstream end of the longitudinal opening to thereby limit the outward range of movement of the valve member from the opening. As a result, the valve member and the downstream end of the longitudinally extending opening define an annular fuel metering orifice therebetween to regulate the flow of fuel from the nozzle.

    摘要: A shape memory alloy actuator assembly for a fuel injector, wherein the response times of the shape memory alloy element is decreased to less than about 1 millisecond by forced, convective heat transfer from the SMA element or elements. The forced, convective heat transfer is provided by the circulation of fluid across the SMA element by a metering orifice plate, which directs a fluid flow across the SMA element so as to maximize the area of contact between the fuel and the SMA element, regardless of whether the fuel injection valve is opened or closed. Use of forced convective heat transfer in accordance with the present invention allows greater power input levels than previously possible without resulting in an over-temperature condition of the SMA alloy, as well as constant response times.

    摘要: A solid-oxide fuel cell system having a relatively large primary fuel cell sub-assembly for steady-state operation and a relatively small secondary fuel cell sub-assembly which is rapidly heatable to a threshold operating temperature to a) produce usable power in a short time period, b) cascade a hot exhaust into the primary fuel cell sub-assembly to assist in preheating thereof, and c) provide steam into the primary fuel cell sub-assembly to prevent coking of the anodes thereof. As the primary sub-assembly reaches its threshold temperature, it too begins to generate electricity and continues to self-heat and to be heated by the secondary sub-assembly. Preferably, the secondary sub-assembly continues to provide electricity in complement with the primary sub-assembly until the primary sub-assembly reaches full power, at which time the secondary sub-assembly may be shut down or switched to standby status for fuel efficiency, as desired.

    摘要: An exhaust system can comprise a NOx adsorber, a reformer disposed upstream of a NOx adsorber and in fluid communication with a fuel source, a first valve for controlling the introduction of the fluid to an exhaust conduit; and a particulate filter disposed upstream and in fluid communication with the NOx adsorber and downstream an in fluid communication with the reformer such that the first valve controls introduction of fluid to the exhaust conduit upstream of the particulate filter. The reformer can be designed to generate a fluid comprising sufficient thermal energy, hydrogen, and carbon monoxide. Optionally, the particulate filter can be designed to be regenerated by the thermal energy and to adsorb a sufficient amount of the thermal energy to reduce the temperature of a gas stream comprising the fluid from a first temperature of about 600° C. to about 1,000° C. to a second temperature of less than or equal to about 500° C.
