  • Fuel pump assembly
    Patent number: 9291132
    Abstract: A high-pressure fuel pump assembly for use in an internal combustion engine is disclosed. The fuel pump assembly comprises a pumping plunger for pressurizing fuel within a pump chamber during a plunger pumping stroke, and being slidably received in a plunger bore; a rider member co-operable with a drive; and an interface member for imparting drive from the rider member to the pumping plunger to perform the plunger pumping stroke, the interface member having an interface side co-operable with the rider member). The pumping plunger comprises fluid delivery means for delivering fuel from the pump chamber to one or more contact surfaces of the pumping plunger, thereby to lubricate the contact surfaces.

  • Method for operating a reciprocating-piston internal combustion engine
    Patent number: 6513487
    Abstract: A method for operating a reciprocating-piston internal combustion engine, having an injector nozzle operable by a single valve element and configured to directly inject a fuel into a combustion chamber and having a piston including a piston crown and a piston recess, includes the steps of injecting the fuel by the injector nozzle into the combustion chamber in the form of separated jets of the fuel having different inclinations relative to a top surface of the piston crown and selectively setting the inclinations of the fuel jets depending on an engine load.
