    摘要： A hydromechanical fuel pump system of supplying timing fluid and fuel to high pressure fuel injectors utilizing a hydromechanical fuel control circuit to control the flow of fuel that is withdrawn from a fuel reservoir by a pump and delivered to the fuel injectors which includes a speed signal generator that produces a fuel pressure in a speed signal branch line of the fuel control circuit that is a function of engine rpm, and a torque shaping module that is provided in a fuel delivery branch of the fuel control circuit. The torque shaping module controls the supply pressure of the fuel flow to the injectors so that, during an initial engine operating range, the supply pressure is merely that as received from the fuel pump, in a second engine operating range, the torque shaping module causes the supply pressure to be a function of fuel pressure in the speed signal branch line as boosted by an assist means, the effect of which is removed in a third engine operating range, and in a last engine operating range, the supply pressure is determined by partially offsetting the effect of the pressure in the speed signal branch line by a counterpressure factor.

    摘要： A unit fuel injector assembly (2, 88) is disclosed for periodically injecting fuel of a variable quantity on a cycle to cycle basis as a function of the pressure of fuel supplied to the injector from a source of fuel (48) and at a variable time during each cycle as a function of the pressure of a timing fluid supplied to the injector from a source of timing fluid (54). A reciprocating plunger assembly (24,146) is received within the injector body (10, 106) and includes an upper plunger section (26, 148), a lower plunger section (28,150) and an intermediate plunger section (30,152) in order to define a variable volume timing chamber (32,138), a variable volume injection chamber (34,162) and a variable volume compensation chamber (36,176). Biasing means (38) including upper compression spring (40,180) and lower compression spring (42, 182) are arranged in the compensation chamber (36,176) to independently bias the lower plunger section (28,150) and the intermediate plunger section (30,152) in opposite directions to tend to collapse the timing chamber (32,138) and injection chamber (34,162). A plurality of passages (58,158,188,194) are provided to cause both the timing chambers (32,138) and the injection chamber (162) to be spilled near the end of each injection event to produce a sharper end of injection and compensation for wear in the cam-operated, actuating mechanism (4).

    摘要： An internal combustion engine is provided including an injector having an injector body including a nozzle assembly having an annular outer surface. A cylinder head includes an injector mounting bore to receive the injector, and a lower sealing portion. The engine also includes an engine coolant passage formed in the cylinder head to receive engine coolant to remove heat from the cylinder head. The engine coolant passage opens into, and is fluidly connected to, the mounting bore to cause coolant in the coolant passage to contact the annular outer surface of the nozzle assembly. A lower seal is positioned between the lower sealing portion and the nozzle assembly to form a fluid seal.

    摘要： A fuel injector having a nozzle with improved cooling including a retainer and a nozzle housing received therein. The nozzle housing includes a nozzle shank, an outer peripheral surface and at least one injection hole at a tip of the nozzle shank. The nozzle shank is positioned in a nozzle support portion of the retainer. In one embodiment, the outer peripheral surface of the nozzle shank is tapered, and the inner peripheral surface of the nozzle support portion is correspondingly tapered and sized to engage the outer peripheral surface of the nozzle shank along a tapered interface. In another embodiment, the inner peripheral surface of the nozzle support portion has a diameter smaller than a diameter of the outer peripheral surface of the nozzle shank so that an interference fit exists at a seal interface. In yet another embodiment, a nozzle seal seals an interface between the inner peripheral surface of the retainer and the outer peripheral surface of the nozzle shank to thereby prevent entry of hot gases into the interface. In another embodiment, the nozzle support portion is provided on a nozzle sleeve.

    摘要： An improved fuel injector is provided which effectively controls fuel injection events using two injection control valves which operate in series to control the movement of a nozzle valve element. An outer injection control valve and actuator assembly operates to control fluid pressure in a control volume adjacent an inner injection control valve thereby controlling the movement of the inner control valve which, in turn, controls fuel pressure in an inner control volume adjacent one end of the nozzle valve element. A particular design of the inner injection control valve prevents control valve oscillations thereby minimizing unwanted fuel injection variations.

    摘要： In accordance with preferred embodiments of the invention a timing adjustment device includes a cam follower that is engaged between an overhead cam and an injector rocker arm, and is mounted on a rotatable eccentric shaft. The geometry of the eccentric shaft and cam follower is designed so that, as timing is varied by rotation of the eccentric shaft, no change is produced in the vertical height of the rocker arm when the cam shaft is on the outer base circle and the injector is bottomed, in order to assure that the "mechanical crush" of the PT type injector is constant despite changes in timing. In a first application of the timing arrangement, it is used together with a simple injector, which does not utilize a multi-plunger arrangement to form a hydraulic link, to achieve lower parasitic losses. To obtain independent control over injection pressure and timing, a fuel injector in which a hydraulic link is formed between plungers of a multi-plunger arrangement is used with the timing arrangement in order to allow the injection pressure to be maintained constant over a wide range of engine speeds without interfering with engine timing.
