Abstract: An intensifier quill for a fuel injector fluidly connects a fuel injector to a common rail. The intensifier quill selectively supplies fuel to the fuel injector at either an intensified pressure or un-intensified common rail pressure. Fuel supplied by the quill at both the intensified and un-intensified pressure passes through a quill body, which includes an actuation chamber, a control chamber and a pressurization chamber. Energizing an actuator of the quill allows fuel from the control chamber to flow to drain, increasing pressure inside the pressurization chamber and the fuel injector to intensified pressure. Upon energizing the actuator of the fuel injector, fuel injector injects fuel at the intensified pressure. When the quill's actuator is de-energized and the fuel injector's actuator is energized, fuel injector injects fuel at the un-intensified pressure.

Abstract: A method of repairing a housing for a machine system includes returning an inner diameter of at least one bearing bore of the housing to a uniform diameter state. The at least one bearing bore is prepared for resurfacing via removing deeply entrapped grease from within pores in cast surface material of the housing subsequent to returning the inner diameter to a uniform diameter state. Subsequent to preparing the at least one bearing bore for resurfacing, it is resurfaced with a material different from cast material of the housing and bonded therewith, for example via thermal spray coating. Resurfacing a cast metallic component, of iron, steel, or the like with metal spray coating may include removing deeply embedded grease from pores of cast surface material of a cast component, in preparation for spraying the cast component with metal spray resurfacing material.

Abstract: A mechanically actuated electronically controlled fuel injector (MEUI) includes a first electrical actuator that controls the position of a spill valve, and a second electrical actuator to control pressure on a closing hydraulic surface associated with a directly operated nozzle check valve. The fuel injector is actuated via rotation of a cam to move a plunger to displace fuel from a fuel pumping chamber either to a spill passage, or at high pressure out of a nozzle outlet of the fuel injector for an injection event. The minimum controllable fuel injection quantity, especially as it relates to small closely coupled post injections following a large main injection, is accomplished by the inclusion of a Z orifice passage that maintains a fluid connection between a needle control chamber and the nozzle supply passage.
