    • This disclosure deals with a fuel injector for an internal combustion engine. The injector includes an injector body having a fuel metering chamber formed therein which receives fuel from a fuel supply. A plunger is movable into the chamber in an injection stroke to force fuel from the chamber and out of the injector through spray holes. A valve member is mounted in the path of fuel flow from the chamber to the spray holes, the valve member being movable between first and second positions. In the first position, the valve member seals the path and prevents air in the combustion chamber from mixing with the fuel being metered into the metering chamber, and in the second position the valve member closes the spray holes to terminate injection. During an injection stroke, the plunger moves the valve member from the first position toward the second position, and fuel injection takes place while the valve member is intermediate the first and second positions. The valve member is also subjected to hydraulic forces at the end of the injection stroke, which move the valve member into the second position in order to abruptly terminate injection.

    • A unit fuel injector is provided comprising an injector body containing a pumping chamber and a valve element provided for movement between (i) an advanced position wherein a supply passage communicates with the pumping chamber through a transfer passage and (ii) a retracted position wherein communication between the supply passage and the pumping chamber is blocked to allow fuel to flow from the pumping chamber through the transfer passage and out the discharge orifice. In one embodiment the valve element includes a control valve integrally formed with a tip valve, and a force balancing element for tending to balance the forces acting on the valve element by reducing the effective cross-sectional area upon which fluid pressure operates. The control valve, whether formed integral with or separate from the tip valve, extends through the solenoid to engage a valve seat formed adjacent the pumping chamber. The armature of the solenoid assembly is sized to be operatively positioned adjacent the stator inner pole without extending to a position adjacent the outer pole. The fuel transfer passage may be at least partially formed in the control valve.

    • A fuel injector having both stepped and infinitely variable timing is disclosed. The fuel injector includes an injector housing and a plunger wherein the plunger includes an axial bore formed in the top of the plunger. A plunger top is mounted within the axial bore and is translatable between an upper position and a lower position. A coil spring having a predetermined spring rate is disposed in the axial bore for biasing the plunger top in the upper position. An upper and a lower piston are disposed above the plunger and are translatable within the injector housing. A timing chamber is formed between the upper piston and the lower piston. When the timing chamber contains timing fluid, the fluid serves as a hydraulic link between the upper and lower pistons and the fuel injector operates at a first level of advanced timing. When the timing fluid creates a force on said lower piston which is greater that the force created by the coil spring, the plunger top is pushed toward the lower position to operate the fuel injector at a second level of advanced timing. The second level of advanced timing is more advanced that the first level of advanced timing and may be infinitely variable.

    • A pump-line-nozzle fuel injection system in which a supply pump is coupled to a high pressure pump having a plurality of pumping cylinders, each of which has a cam-driven timing plunger and a floating metering plunger. During the retraction stroke, flow to a timing chamber formed between the pistons is blocked by a solenoid valve while the fuel passes into a metering chamber, at the discharge side of the pump, which is closed relative to the high pressure delivery line by a delivery valve. Once the proper quantity of fuel has been metered, the solenoid valve opens allowing fuel to flow into the metering chamber, balancing the pressure on opposite sides of the metering piston, so as to prevent the metering plunger from retracting further as the timing plunger continues to retract. During the compression stroke, at the appropriate time for commencement of injection, the solenoid valve recloses creating a hydraulic link between the metering and timing plungers, so that the fuel is pressurized. Once the fuel is sufficiently pressurized, the delivery valve opens and the fuel is delivered to the injector via the high pressure delivery line. Each pumping cylinder delivers fuel to a respective associated injector for each cylinder of the engine. Compressibility of the fuel and the length of the high pressure delivery line is compensated for by an electronic control module and by making the timing plunger of a larger diameter than the metering plunger so as to obtain a fast pumping rate.

    • An air fuel ratio control for an I.C. engine fuel supply system is disclosed including a diaphragm operator for a fuel flow modulating valve responsive to engine intake manifold pressure as sensed through an air line connecting the diaphragm operator with the intake manifold and a drain line for returning to the engine fuel tank all fuel which may leak into the diaphragm operator due to seal rupture. The disclosed system further including a specially designed flow restrictor in the air line to prevent engine fuel tank pressurization and reverse fuel flow into the engine's intake manifold should the diaphragm operator rupture. The flow restrictor includes a control orifice which is sufficiently large to allow proper control by the diaphragm operator but yet not so large as to allow fuel tank pressurization should the diaphram rupture. In one embodiment the flow restrictor includes a check valve designed to close only upon improper fuel flow from the air fuel control to the intake manifold. To avoid manufacturing tolerances, the check valve may be calibrated to close at precisely the proper miminal flow rate.
