Abstract: A valve includes a valve body having a valve plunger barrel formed therein and configured to be mounted to a pump head of a fuel pump, a valve plunger arranged to perform reciprocal motion with respect to the valve plunger barrel, a drive assembly configured to cause the valve plunger to perform reciprocal motion, and a spacer configured to couple to the valve plunger to perform reciprocal motion together with the valve plunger and configured to interface with the pump head. The spacer has a spacer body with first and second opposing spacer surfaces and with a central aperture extending from the first to the second spacer surface and configured to receive the valve plunger therethrough. At least one of the first and second spacer surfaces includes one or more grooves recessed into the spacer body to reduce or inhibit cavitation of the interface of the spacer and pump head.

Abstract: The present disclosure provides a system for adjusting a fuel injector drive signal during a fuel injection event wherein the system comprises an engine having a fuel injector, a fuel control module configured to generate control signals corresponding to a desired fueling profile of a fuel injection event, and a fueling profile interface module that outputs drive profile signals to the fuel injector in response to the control signals to cause the fuel injector to deliver an actual fueling profile, wherein the fueling profile interface module changes the drive profile signals during the fuel injection event in response to a parameter signal indicating a characteristic of the actual fueling profile.

Abstract: Fueling systems and methods are disclosed. Various fueling systems may comprise a single fuel pump configured to supply fuel to a first fuel rail at a first fuel pressure along a first fuel circuit and configured to supply fuel to a second fuel rail at a second fuel pressure along a second fuel circuit, wherein the first fuel rail and second fuel rail are arranged in parallel, and the first fuel circuit is independent of the second fuel circuit.
