摘要： A fuel filtration system is provided. The fuel filtration system includes a pump configured to receive a flow of fuel from a fuel storage tank and at least one filter positioned downstream to the fuel filtration system and fluidly coupled to the pump. The fuel filtration system further comprises a recirculation loop configured to recirculate at least a portion of the fuel through the at least one filter. The recirculation loop is also configured to provide a remaining portion of the fuel to an engine during the recirculation. The remaining portion of the fuel is determined based on a fuel consumption of the engine.

摘要： A fuel filtration system includes an electric pump, a filter assembly, and conduits for fluidly connecting the pump and filter assembly in series with a fuel tank to define a kidney filtration loop. The filter assembly includes a filter assembly head, including attachment openings therethrough, and a filter exchange module, including a mounting plate having externally threaded mounting connectors extending outwardly from one face thereof and internally threaded bores opening through another face thereof. In a mounted configuration, a fuel filter is threaded onto each mounting connector such that the filter is fluidly aligned with a fuel flow opening through the mounting plate, fasteners are positioned through the attachment openings and threadably received within the bores, and fuel flow passages of the filter assembly head define a flow distribution in which one pair of filters is fluidly in parallel and another pair of filters is fluidly in series.

摘要： Mixing of lubrication fluid and pumped fluid within a pump can undermine lubricity of the lubrication fluid and/or contaminate the pumped fluid (e.g. fuel) with lubrication fluid. In order to reduce mixing of fluids within a high pressure pump of the present disclosure, a lubrication fluid is supplied to the high pressure pump. A low pressure pump supplies a second fluid to the high pressure pump. The pressure of the second fluid is increased within at least one piston bore of the high pressure pump. Mixing of the lubrication fluid and the second fluid is reduced by fluidly connecting a weep annulus which is opened to the at least one piston bore to a low pressure pump inlet of the low pressure pump.

摘要： A pump and rail assembly includes a plurality of quills that are compressed between quill seats on a pump and an output rail. A rail pressure control valve and a rail pressure sensor are attached to respective ends of the output rail. An inlet throttle valve is attached to a housing of the pump and rail assembly. Depending upon the application, the output rail may supply fuel to a first injection bank that includes a plurality of fuel injectors in a first common rail, and a second fuel injection bank that includes a second common rail and a plurality of fuel injectors. Different engines having different numbers of cylinders may use similar pump and rail assemblies that each include a plurality of quills, a plurality of pumping elements positioned in a pump housing and an output rail. The quills for each of the different engine applications are interchangeable but differ in number. In addition, the pumping elements of each of the different engine applications are also interchangeable but differ in number.

摘要： A pumping element for pressurizing a fluid within a fluid pump includes a plunger reciprocally disposed within a bore defined in a barrel. The plunger and barrel at least partially define a pressurization chamber into which fluid is pressurized. A flow path is defined between the plunger and the bore, the flow path permitting fluid to pass from the pressurization chamber during pressurization of fluid disposed therein. A collection chamber is formed between the plunger and the bore, the collection chamber being disposed adjacent to the bore and being part of a cooling circuit for the pumping element. A plurality of weep openings is defined in the barrel and is fluidly connected to the collection chamber. A reduced diameter portion of the barrel forms an annular reservoir that receives fluid from the weep openings.

摘要： In an engine equipped with a common rail fuel injection system, the engine can sometimes experience an overspeed condition, and the pump may respond to this overspeed condition with self-actuation even in the absence of any control signal. In order to prevent an over pressurization condition, a liquid supply into a pumping chamber of the pump is limited during a retraction stroke of a pump plunger by energizing an electrical actuator coupled to a spill valve, to move the spill valve toward a closed position. The electrical actuator is de-energized during a pumping stroke of the pump plunger to allow the spill valve to more toward an open position. Liquid from the pumping chamber is discharged through the spill valve during the pumping stroke, but over pressurization is avoided by limiting the amount of liquid that can enter the pumping chamber during the retraction stroke.

摘要： Because of the relatively high pressures experienced within fuel injectors, several internal components can undergo substantial deformation each time fuel is pressurized to injection levels. In some instances, such as when a solenoid operated control valve is positioned near a distortion region, the internal distortion can cause a fuel injector to behave with less predictability, and can undermine consistency from one fuel injector to another, since distortion levels and affects therefrom are likely to vary substantially from one injector to another. In order to desensitize fuel injector performance to this internal distortion, a deflection cavity is disposed within the fuel injector between the distortion region and the needle valve of the fuel injector. This strategy finds particular applicability to needle control valves disposed deep within fuel injectors in order to control fluid pressure on a closing hydraulic surface of a direct control needle valve, which opens and closes the nozzle outlets.
摘要翻译：由于燃油喷射器中经历的压力相对较高，每当燃料被加压至喷射水平时，几个内部部件可能经历相当大的变形。在一些情况下，例如当螺线管操作的控制阀位于变形区域附近时，内部变形可能导致燃料喷射器以较少的可预测性表现，并且可能破坏从一个燃料喷射器到另一个的一致性，因为失真水平和影响可能从一个注射器到另一个注射器显着变化。为了使燃料喷射器的性能降低到这种内部变形，在燃料喷射器内在燃料喷射器的变形区域和针阀之间设置偏转腔。该策略特别适用于布置在燃料喷射器内部的针控制阀，以便控制打开和关闭喷嘴出口的直接控制针阀的关闭液压表面上的流体压力。

摘要： A thin film coating for a low allow steel or tool steel components in a fuel injector (14), such as a fuel injector needle valve (86) is disclosed. A thin film coating (96) consists of a metal carbon material layer less than 2.0 microns thick applied to a low alloy steel substrate (95) or tool steel substrate (95) used in fuel injector components, such as the fuel injector needle valve (86) or a portion thereof. Optionally, a thin bond layer (98) of chromium is deposited between the steel substrate (95) and the primary metal carbon material coating (96). The thin film coating (96) minimizes abrasive and adhesive wear associated with the needle valve (86) and cooperating nozzle surfaces (62,63) of the fuel injector (14).
