ABSTRACT:
A coating for fuel injector components adapted for use with low lubricity fuels is disclosed. The invention consists of a metal carbon material coating or a metal nitride coating to the fuel pump plunger or other fuel injection system components. The invention utilizes a coating on the fuel injector plunger that minimizes scuffing or seizure associated with the plunger and barrel.
