Abstract: A plunger pump includes a housing with a discharge valve in communication with an outlet. The housing includes a bore that slidably accommodates a plunger. The housing also includes an inlet. The plunger has a closed proximal end connected to an actuator and a distal end with an outlet valve. The plunger also includes a sidewall with an opening that is in communication with the inlet of the housing. Fluid flows through the inlet and through the opening and into the plunger. When the plunger is retracted away from the discharge valve, the outlet valve of the plunger opens thereby providing fluid for the housing bore. As the plunger is moved towards the discharge valve, pressure in the housing bore increases thereby opening the discharge valve and permitting the pressurized fluid to exit through the outlet.

Abstract: A system for selectively intensifying fuel for injection utilizing a fuel injector having an intensifier piston connected to a drain and a pressurized fuel source. The intensifier piston includes a control chamber co-axially positioned opposite from an intensification chamber, and a pressurization chamber co-axially positioned between the control chamber and the intensification chamber. The control chamber selectively fluidly communicates with the pressurized fuel source and the drain. The intensification chamber fluidly communicates with the pressurized fuel source and the pressurization chamber fluidly communicates with the pressurized fuel source and a nozzle assembly.

Abstract: A regeneration device is disclosed. The regeneration device has an injector configured to inject pressurized fuel during an injection event. The regeneration device also has a heater configured to ignite the pressurized fuel during the injection event. The heater is also configured to purge the injector between injection events.

Abstract: A method of assembling an apparatus such as a fuel injector (200) wherein parts or components are selected based on their capacity to compensate for variations in timing and delivery contributed by the tolerance variations of components assembled or measured for assembly prior to the selected components. The method involves an apparatus such as an injector of the type including a set of input parameters, a set of control parameters, and a set of observed performance parameters wherein the method includes the steps of performing tests (214, 216, 218, 220) on the injector (14) to measure the values of the input parameters and determining the values of the set of control parameters (222) using the set of input parameters to reduce performance parameter variability of the final assembly. The method also includes the steps of selecting (232, 234), for each control parameter, the component associated therewith and, assembling the selected components into the injector (14).

Abstract: A valve for use in a fuel injector includes a moveable valve member disposed in a first chamber and an armature coupled to the valve member and reciprocally disposed in a second chamber which dampens the motion of the valve member when fluid is present in the second chamber. A fluid passageway extends into the second chamber and delivers fluid to the second chamber while a further fluid passageway drains fluid from the second chamber when the fluid within the second chamber reaches a predetermined level.
