Abstract
A method of manufacturing a fuel injector having high-flow orifices in its tip includes removing a bulb from a fuel injector tip having at least one spray orifice with a first diameter, and friction welding a slug to the fuel injector tip, including forming a fused interface of material of the slug and material of the fuel injector tip. The method further includes modifying the slug subsequent to friction welding the slug to the fuel injector tip, including forming a new bulb from the slug having at least one spray orifice therein with a different diameter than that of the removed bulb. A remanufactured fuel injector, and fuel injector tip, includes an injector tip body having a first tip portion of a first material and a second tip portion of a material compatible for friction welding with the first material. The injector tip body further includes a third tip portion attaching the first tip portion to the second tip portion, the third tip portion including a friction weld formed during remanufacturing of the fuel injector tip.
