摘要： A fuel swirler plate for improving atomization of fuel in a fuel injector. A plurality of identical fuel supply passages is formed in the plate, each passage including an outer fuel reservoir region; a region having converging walls wherein fuel is accelerated and turned partially tangential to the axis of the plate and fuel injector; a metering region wherein flow is regulated; and an exit region wherein the fuel is combined with similar fuel flows from the other passages to form a high velocity swirl annulus between the swirler plate and a pintle ball of the fuel injector. An advantage of the novel swirl plate over prior art plates is that, when the injector valve is closed, only a very small volume of fuel resides in the swirl annulus between the pintle ball and the exit region of the plate, and such residual fuel is urged rotationally and becomes the leading edge of a new vortex the next time the valve is opened, thus minimizing SAC spray formation. The present invention is useful in fuel cells, burners, and in both direct injection and port injection fuel injectors of internal combustion engines.

摘要： A three-way gas control valve assembly for selectively controlling gas flow from one inlet port into two outlet ports or vice-versa, such as may be required for flow control of hydrogen-containing reformate in fuel cell applications. The valve assembly comprises three subassemblies: a metering subassembly disposable within the high-temperature environment in the fuel cell for mechanically regulating reformate flow; an actuating subassembly disposable outside the fuel cell and connected to the metering subassembly for actuating a pintle shaft and valve head in the metering subassembly; and a coupling tube subassembly extendable through an insulative shroud to mechanically couple and thermally isolate the metering and actuating subassemblies.

摘要： A fuel injector that includes a flying armature movable relative to a pintle stop, and an electromagnetic circuit configured to move the flying armature away from the pintle stop prior to accelerating the armature toward the pintle stop as part of moving the pintle to open the fuel injector. The flying armature increases the total force applied to the pintle to open the fuel injector by supplementing the static force imparted to the armature by a magnetic field with an impact force imparted by the armature being in motion toward and impacting with the pintle stop. The arrangement of magnetic circuit devices and materials used to make the magnetic circuit devices cooperate to provide a reversing force that urges the armature away from before urging the armature toward the pintle stop, and increases the rate at which the force that urges the armature toward the pintle stop increases.

摘要： A fuel injector assembly incorporating a heat exchanger and a fuel injector and being disposable in a bore in a mounting substrate such as an internal combustion engine or a hydrocarbon fuel reformer. The exchanger includes an outer wall in direct contact with the bore and also surrounds and supports the dispensing portion of the fuel injector, forming an annular plenum space therebetween. The heat exchanger has an inlet port and an outlet port communicating with the plenum space. The exchanger outlet port is connected to an inlet port of the fuel injector, such that fuel entering the fuel injector is preheated by passing first through the heat exchanger. In some applications, it may be desirable to maintain the fuel at a high pressure to prevent premature vaporization of the fuel in the exchanger and resulting vapor lock of the fuel system.
