Abstract: A method of controlling wear in a fuel injector assembly is provided. The method can include selecting an injector assembly including a fuel injector plunger including a plunger substrate material and a first coating on the plunger substrate material, and a fuel injector bore including a bore substrate material and a second coating on the bore substrate material. The first and second coatings of the plunger and bore are in sliding engagement and can include chromium nitride. Fuel may be supplied to the bore assembly using a fuel that includes at least one of an ultra-low sulfur fuel and a low lubricity fuel.

Abstract: A fuel pump assembly is provided. The assembly includes a first pump component having a first substrate and a first coating disposed on the first substrate. The assembly further includes at least one second pump component having a second substrate and a second coating disposed on the second substrate, wherein the first and second coatings are configured to repeatedly impact one another. In addition, the first coating may be selected from the group consisting of metal nitrides and diamond like carbon, and the second coating may be selected from the group consisting of metal nitrides and diamond like carbon.
