摘要： A fuel injector includes an injector housing having a plunger assembly disposed within a central axial bore and including a lower plunger, an intermediate plunger, and an upper plunger. The lower plunger reciprocates within the central bore to meter a variable quantity of fuel during downward portions of the reciprocating motion. A timing spring is wound around the upper portion of the lower plunger to bias the lower plunger upwardly. A timing chamber formed between the upper and intermediate plungers receives timing fluid to create a hydraulic link between the plungers. Timing fluid exits the timing chamber through a central passage, which may have a reduced area regulating orifice, formed through the intermediate plunger, which is ordinarily closed by a valve mechanism. The valve mechanism is acted upon in part by the timing spring. To improve the pressure regulation using a higher spring load and to accommodate a larger area drainage passage, a valve spring biases closed the passage. The force provided by the valve spring is predetermined to open the valve mechanism and drain timing fluid when the timing fluid pressure exceeds the maximum pressure during injection. After injection is completed, timing fluid exits from the timing chamber either through the central passage or through a spillport which is closable by the nonbeveled lower portion of the upper plunger.

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to high pressure fuel injectors utilizing a hydromechanical fuel control circuit to control the flow of fuel that is withdrawn from a fuel reservoir by a pump and delivered to the fuel injectors which includes a speed signal generator that produces a fuel pressure in a speed signal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： A metering system is provided which controls the amount of fuel supplied to the combustion chambers of a multi-cylinder internal combustion engine comprising a fuel pump for supplying fuel at low pressure to a first and a second group of unit fuel injectors, a first solenoid-operated fuel control valve controlling the flow of fuel to the first set of injectors and a second solenoid-operated fuel control valve controlling the flow of fuel to the second set of injectors. The system may also include first and second solenoid-operated timing fluid control valves associated with the first and the second group of injectors, respectively. The injectors are capable of being in the fuel receiving mode, establishing a metering period, and the timing receiving mode, establishing a timing period, at the same time to increase the amount of time available for metering both timing fluid and fuel. By grouping the various injectors based on the order of injection so that the injectors from each group are placed in the injection mode in spaced periods throughout each cycle of the engine, e.g. injectors from other groups injecting in the period of time between each injection mode, the system can be designed to permit longer metering and timing periods.

摘要： A preferred embodiment EGR valve permits exhaust gas to be induced into the intake line downstream of the compressor, while minimizing the need to reduce the size of the turbocharger. The preferred embodiment EGR valve exploits variations around the mean pressure in the EGR passage created by the engine cycle by selectively opening when the pressure in the EGR valve exceeds the pressure in the intake line. Thus, exhaust gas is recirculated even when the engine is running near torque peak. The preferred embodiment EGR valve also exploits the higher mean pressure in the exhaust line relative to the intake line at higher engine speeds by remaining open, in order to minimize the energy consumed in opening and closing the EGR valve.

摘要： A variable displacement high pressure pump having a plurality of high pressure pumping units which receive fuel from a low pressure fuel pump. A rotary cam-driven roller tappet, for producing pumping displacement of the pumping plunger of a respective pumping element, is connected to the pumping plunger by a separated link in a manner permitting the pumping plunger to float relative to the roller tappet during at least a portion of each pumping cycle. As a result, the capacity of the pumping chamber can be limited to an extent that is less than the full stroke achievable by the pumping plunger being retracted to the maximum extent which is permitted by the driving cam. In this way, the quantity of fuel to be pressurized and injected into the common rail does not have to be determined by a cutting-off of a spilling flow of excess metered fuel during the compression stroke of the pumping plunger, so that a low pressure solenoid valve can be used, in the case of time-stroke and time-pressure metering, and no solenoid is required to control metering in the case of pressure-time metering.

摘要： A fuel distributor is provided which is capable of distributing fuel through plural fuel injection lines to the corresponding cylinders of a multicylinder internal combustion engine and which includes a distributor housing including a supply inlet passage, a plurality of fuel injection outlet passages and a plurality of distributor valves for providing sequential periodic fluidic communication between the supply inlet passage and the outlet passages. Each distributor valve, which may be cam-actuated or solenoid-actuated, is adapted to be placed in an open position to define a fuel injection period during which high pressure fuel may flow through the distributor valve to the respective engine cylinder and a closed position blocking fuel flow through the respective fuel injection outlet passage. Each of the distributor valves is adapted to receive a force from the high pressure fuel flowing from the supply inlet passage which urges the distributor valve into the closed position thereby providing an effective seal and minimizing leakage. The distributor may be used in a high pressure fuel system having a control valve positioned between a high pressure accumulator and the fuel distributor for controlling the flow of high pressure fuel to the distributor. The control valve is moveable to define a fuel injection event, occurring within the injection period provided by each distributor valve, during which high pressure fuel may flow from the high pressure supply means through one of the distributor valves to a respective engine cylinder.

摘要： An electronically controlled fuel supply system is provided for employing a plurality of fuel injectors which maximize SAC pressures under both low speed and high speed operating conditions and are capable of sustaining SAC pressures in excess of 30,000 psi. The fuel supply system of the present invention includes a gear pump which supplies pressure-modulated fuel to a fueling channel and to a timing channel and from there to a plurality of injectors. Fuel pressure regulator means and timing fluid pressure regulator means are provided in the fueling and timing channel, respectively. An electronic control unit receives information relating to engine operating conditions from a plurality of sensors and actuates the fuel pressure regulator means and the timing fluid pressure regulator means to adjust the pressure as required for the specific engine operating conditions. The timing fluid is delivered to the injectors by the present system at a pressure sufficient to sustain a hydraulic link within the injector of the length necessary to maintain high SAC pressures during injection. Several embodiments of a fuel supply system which achieves these objectives are disclosed. A mounting integral with the cylinder head for an electronically controlled injector fuel supply system is also provided.
