Remanufactured Fuel Injector Tip And Fuel Injector Tip Remanufacturing Process

US Patent:
7866574, Jan 11, 2011
Filed:
Jan 22, 2007
Appl. No.:
11/656193
Inventors:
Karen Raab - Peoria IL,
James D. Sparks - Edelstein IL,
Scott A. Johnston - East Peoria IL,
Sami El-Sayed - Peoria IL,
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F02M 59/00
US Classification:
2395332, 239 88
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.

B23P 6/00
B29C 73/00
US Classification:
264 3617, 264314, 29888011
Abstract:
A method for repairing a wear-induced void associated with a surface of a component including applying a heat-cured ceramic material to the wear-induced void, wherein the heat-cured ceramic material is configured to substantially fill the wear-induced void and providing a volume of material to a bladder configured to retain the volume of material and expand in one or more directions, wherein at least a portion of the bladder is further configured to apply at least one of pressure and heat to the heat-cured ceramic material. The method further includes applying at least one of pressure and heat, via the bladder, to the heat-cured ceramic material.

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B05D 3/02
B05D 3/04
B05D 3/06
H05B 6/02
H05B 6/36
H05B 6/40
US Classification:
427543, 427591, 427226, 4273765
Abstract:
A method of coating a component is disclosed. The method includes applying a coating composition to a surface of the component. The method also includes providing an induction coil having a coil configuration corresponding to the surface.
