Capillary fuel injector with metering valve for 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.
