    摘要： 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. The system for metering vaporized fuel includes 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 the liquid fuel in the at least one capillary flow passage to a level sufficient to change from the liquid state to a vapor state and deliver a stream of vaporized fuel from the outlet end of the at least one capillary flow passage. The system for metering vaporized fuel further includes a valve for metering vaporized fuel located downstream to the outlet end of the at least one capillary flow passage. The fuel injector is effective in reducing cold-start and warm-up emissions of an internal combustion engine.

    摘要： A fuel injector for vaporizing a liquid fuel for use in an internal combustion engine. The fuel injector includes at least one capillary flow passage, a heat source arranged along the at least one capillary flow passage, the heat source operable to heat the liquid fuel in the at least one capillary flow passage 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 the outlet end of the at least one capillary flow passage; and a valve for metering fuel to the internal combustion engine, the valve located proximate to the outlet end of the at least one capillary flow passage, the valve including a low mass member for substantially occluding the stream of fuel to the internal combustion engine; wherein the low mass member for substantially occluding the stream of fuel to the internal combustion engine is formed of a material having low mass and or a low coefficient of thermal conductivity. The fuel injector is effective in reducing cold-start and warm-up emissions of an internal combustion engine.
