摘要： A unit pump (10) is provided with a bleed port (12) spaced from the main injection port (14). The bleed port (12) improves the rate shape of injection through an associated fuel injector by slowing the initial rate of injection. The bleed port (12) permits shifting of the engine speed at which speed advance occurs. The bleed port (12) also flattens the fuel backup curve. Altering the cross section flow area (18) of the bleed port, axial spacing between the bleed port and inlet port (20) permit the designer to vary (or even eliminate) the impact of the bleed port (12) on the unit pump (10) performance.

摘要： A clamping and seal loading technique for securing the plunger sleeve to the pump housing of a single plunger fuel pump. This is achieved by providing a load ring between a sleeve retainer and the sleeve, such that the axial force applied by the retainer during installation and attachment to the plunger bore wall of the housing, is distributed more evenly on the sleeve and the sealing surface of the sleeve against the housing adjacent to the pumping chamber. The even distribution of force minimizes misalignment of the sleeve and thus maintains concentricity between the sleeve and the plunger.

摘要： A fuel conditioning structure filters fuel prior to the water separation mechanism. A coalescing media employs hydrophilic synthetic fibers that coalesce water even with the low surface tension present in fuels treated with additives/surfactants. The coalescing media employs a gradient structure of fine fibers/small voids to larger fibers/larger voids in the direction of fuel flow. This structure promotes water adhesion on the fine fibers and coalescence into large whole water droplets that are easily rejected by a water barrier. Pre-filtration extends the life of the coalescing media and water barrier by keeping these structures free of particulates, oxidized fuel and asphaltenes. This configuration helps prevent degradation in the ability of these layers to separate water over the life of the filter.
摘要翻译：燃料调节结构在水分离机构之前过滤燃料。聚结介质采用亲水性合成纤维，即使在用添加剂/表面活性剂处理的燃料中存在低表面张力的情况下也可以聚结水。聚结介质沿燃料流动方向采用细纤维/小空隙至较大纤维/较大空隙的梯度结构。这种结构促进细水纤维上的水分附着并聚结成容易被水障碍物排斥的大整体水滴。预过滤通过保持这些结构不含微粒，氧化燃料和沥青质，延长了聚结介质和水屏障的使用寿命。这种配置有助于防止这些层在过滤器的使用寿命内分离水的能力下降。

摘要： A filter cartridge according to aspects of the present invention positions the outside diameter of the filter element adjacent the inside of the filter cartridge housing. The larger outside diameter of the filter element expands the surface area of filter medium presented to fuel entering the filter cartridge. Positioning the outside diameter of the filter element near the inside surface of the cartridge housing promotes an axial fuel flow pattern across the outside surface of the filter media. This flow pattern is believed to sweep water from the surface of the filter media toward the sump of the cartridge. The flow pattern causes water droplets that coalesce on the outside of the filter media to combine into larger droplets, which then fall into the sump of the cartridge.

摘要： An adapter connects a pump motor of a fuel filter assembly in series with a heater to a 24-volt electrical system. The heater and motor in series act as a voltage divider. The heater is selected so that the total resistance of the voltage divider provides current flow adequate to operate the pump motor. The motor resistance and the heater resistance are approximately equal, producing a voltage drop across each component of approximately 12 volts. With appropriately selected components, no additional electrical or electronic components or circuitry are required. Existing, proven 12-volt motors and heaters can be employed. The 12-volt electrical components of a fuel filter assembly are efficiently adapted to operate in a 24-volt electrical system.

摘要： The invention is directed to the combination of fuel rail pressure control at lower speed using high pressure regulation plus fuel rail pressure control at higher speed using any of a variety of forms of inlet metering. The partial filing control at high speed can in one embodiment include pre-metering the quantity of feed fuel delivered to each pumping chamber, for example by modulating the feed pressure at the pumping chamber inlet. Another embodiment includes passing the feed fuel from the inlet passage through a fixed, calibrated orifice sized to pass sufficient feed fuel to fill the pumping chambers in the charging phase during operation of the engine in the low speed range, while in the high speed range the flow resistance of the orifice prevents the pumping chamber from filling in the charging phase, thereby monotonically decreasing the quantity of high pressure fuel delivered to the discharge passage in the discharge phase per engine revolution, with increasing speed above the transition speed.
