摘要： A closed nozzle fuel injector is provided which effectively controls the fuel injection flow rate, especially during an initial portion of an injection event, while also permitting accurate control over pilot and/or post injection flow rates at all operating conditions thereby advantageously reducing emissions and combustion noise. The injector includes a rate shaping orifice to restrict fuel flow during an initial portion of an injection event and a rate shaping sleeve mounted for movement to cause a greater flow of injection fuel during a later portion of the injection event. A damping chamber and orifice are also provided to control movement of the rate shaping 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： Fuel injector for an internal combustion engine which has a timing chamber bore in its body intersecting at an acute angle with an auxiliary bore. These bores are fuel-receiving passages exposed to the pressure of injection. A radiused intersection between the walls of the respective bores reduces the concentration of stress within the fuel injector, allowing the injector to withstand the high injection pressures of mechanical pressurization. An electrochemical machining method and fixture for machining the intersection between the bores of a fuel injector body or other workpiece is also disclosed.

摘要： A mechanically pressurized electronic fuel injector for use in internal combustion engines is actuated by the engine valve train during the injection stroke. A control solenoid is mounted to the injector and has its axis inclined with respect to the axis of the injector. A control valve passage has its axis generally coaxial with the central axis of the control solenoid. Machining of the control valve passage is accomplished through the receiving boss for the control solenoid. High pressure sealing plugs, previously required to seal orifices in the exterior surface of the injector body which were needed to provide access to drill or machine the control valve passage, are completely eliminated. The drilling and machining of the control valve passage is accomplished without drilling through the exterior surface of the injector body.

摘要： A fuel pump is disclosed wherein a substantially cylindrical plunger bore is provided with an annular drain groove fluidically coupled to a drain duct. A pump plunger is driven by a drive system located in a separate mechanical compartment that holds a reservoir of lubricating oil. An annular seal is provided adjacent the drain groove substantially at the end of the bore and retained in position by a seal support. Exemplary embodiments provide the drain groove and seal as being positioned immediately adjacent one another so that the seal forms a lower wall of the drain groove.
