Abstract
A unit fuel injector is modified for use with low lubricity, low viscosity fuels by the following: providing a replaceable, deformable fluid seal between the brushing and the injector body; providing a drain conduit extending through both the bushing and the injector body which connects a fluid collecting cavity in the bore of the bushing to an exterior drain outlet; providing a pair of non-galling materials respectively on the plunger and bushing; providing diametrically symmetrical fuel ports on the bushing; providing a diametrically symmetrical metering groove arrangement on the plunger; and increasing the spray tip orifices to provide approximately a 20% increase in fuel discharge rate.
