Abstract: A fuel injector for vaporizing a liquid fuel for use in an internal combustion engine. The fuel injector includes a plurality of capillary flow passages, each of the plurality of capillary flow passages having an inlet end and an outlet end; a heat source arranged along each of the plurality of capillary flow passages, the heat source operable to heat the liquid fuel in each of the plurality of capillary flow passages to a level sufficient to change at least a portion thereof from the liquid state to a vapor state and deliver a stream of substantially vaporized fuel from each outlet end of the plurality of capillary flow passages; and a valve for metering substantially vaporized fuel to the internal combustion engine, the valve located proximate to each outlet end of the plurality of capillary flow passages. The fuel injector is effective in reducing cold-start and warm-up emissions of an internal combustion engine.

Abstract: An internal combustion engine and a method of operating same are provided with direct injection of gaseous fuel into a combustion chamber and an ignition assist apparatus disposed within the combustion chamber. An ignition assist apparatus disposed within the combustion chamber comprises an electric incandescent ignitor with a sleeve disposed around the ignitor and a catalytic alloy. The catalytic alloy comprises a first catalytic element with a greater affinity for oxygen than that of a second catalytic element, and the second catalytic element having a greater affinity for the fuel than that of the first catalytic element.

Abstract: A fuel injector for delivering fuel to an internal combustion engine. The fuel injector includes a fuel injector housing, a system for metering vaporized fuel to the internal combustion engine, the system positioned within the fuel injector housing, and a system for delivering an atomized stream of liquid fuel to an internal combustion engine, the system positioned within the fuel injector housing, wherein the fuel injector is operable to transition from metering vaporized fuel to delivering an atomized stream of liquid fuel to an internal combustion engine.

Abstract: A fuel system for use in an internal combustion engine includes a plurality of fuel injectors, each injector including at least one capillary flow passage, the at least one capillary flow passage having an inlet end and an outlet end, a heat source arranged along the at least one capillary flow passage, the heat source operable to heat a liquid fuel in the at least one capillary flow passage to a level sufficient to convert at least a portion thereof from the liquid state to a vapor state, and a valve for metering fuel to the internal combustion engine, a controller to control the power supplied to the heat source of each of the plurality of fuel injectors to achieve a predetermined target temperature, a sensor for use in determining engine air flow and a sensor for measuring a value indicative of degree of engine warm-up of the internal combustion engine.

Abstract: A method for controlling a fuel system of an internal combustion engine. The method is employed with a fuel system having a source of alcohol-containing liquid fuel, at least one fuel injector, a heat source for heating the liquid fuel in the at least one fuel injector, the heat source capable of heating the liquid fuel to a level sufficient to convert at least a portion thereof from the liquid state to a vapor state and a metering valve operable to achieve a range of flow rates characterized by a valve open versus valve closed duty cycle. The method includes the steps of metering a predetermined amount of fuel based on engine operating conditions, controlling power supplied to the heat source of the at least one fuel injector to achieve a target temperature, determining alcohol concentration of the fuel and adjusting the power supplied to the heat source of the at least one fuel injector based on the alcohol concentration determination.

Abstract: A quiver apparatus for mounting on a bow has a mounting interface adapted for attaching the apparatus to the bow and one or more retainers adapted for holding arrows. A support extending away from the one or more retainers and mounting interface is formed such that, with the support resting on a surface, an arrow held in the one or more retainers is held above the surface with no portion of the arrow, including fletching, touching the surface. In some embodiments the support comprises two legs, and the legs may be substantially parallel and directed at substantially a right angle to a plane defined by the shape of the bow. In some embodiments boots are provided for attaching to leg extensions, adapted for providing increased surface area contact.
