FUEL INJECTOR FOR AN INTERNAL COMBUSTION ENGINE

摘要

A fuel injector for vaporizing a liquid fuel for use in an internal combusti on engine. The fuel injector includes at least one capillary flow passage (12), said at least one capillary flow passage (12) having an inlet end (14) and a n outlet end (16), a fluid control valve (18) for placing said inlet end of sa id at least one capillary flow passage in fluid communication with the liquid fuel source (F) and introducing the liquid fuel in a substantially liquid state; and a heat source (20) arranged along said at least one capillary flo w passage (12), said heat source (20) operable to heat the liquid fuel in said 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 said outlet end said at least one capillar y flow passage (12).
