Injector with fuel deposit-resistant director plate |
摘要 |
An engine fuel injector for spraying fuel into an air intake passage includes an injection nozzle having a fuel passage with a valve seat selectively engagable by an electromagnetically-actuated valve member to control fuel delivery through the nozzle. A director plate outwardly adjacent the valve seat includes: an inner side, adapted for exposure to liquid fuel in the nozzle; a plurality of spray openings through the plate, adapted for directing fuel spray into such air intake passage for mixing and vaporization with air charges in the passage; and an outer side, adapted for exposure to mixtures of engine intake air and fuel spray in the intake passage. The director plate has at least a portion formed of a conductive fuel deposit-resistant fluoropolymer material. The plate may be formed of the fluoropolymer or the material may be coated onto a supporting substrate.
