Abstract
Disclosed is an apparatus and method for lubricating a plunger residing within a bushing of a fuel injector. The apparatus includes a fuel lubrication mechanism comprised of lubrication grooves formed within and around the outer axial surfaces of the plunger. The grooves act as fuel reservoirs for storing a small portion of fuel on the outer axial surface of the plunger. The stored or retained fuel interfaces with the walls of the bushing during injection to provide a lubricated interface between the bushing and plunger. The lubricated interface increases the service life of the fuel injector by reducing seizing, scoring and scuffing caused by excessive heat.
