Definitions

  • the present invention relates to a fuel injector and in particular to a fuel injector having improved means for eliminating valve bounce.
  • Modern direct injection gasoline engines require fuel injectors to operate under extreme conditions of temperature and pressure and with high fuel pressures. Furthermore, the fuel injector must open and close very rapidly in order to provide the high linear range required in modern engine applications.
  • valve bounce A particular problem with known solenoid actuated fuel injectors when operated at high speed is valve bounce.
  • the impact of the pintle head against the valve seat can be substantial due to the large mass of the armature connected to the pintle and the force exerted on the pintle by the return spring. Due to the elasticity of the valve surfaces and the stiffness of the pintle the pintle head tends to rebound from the valve seat causing the injector to re-open.
  • Such valve bounce causes one or more unmetered after injections of fuel delivery after injector closing, as shown in Fig 1 . This problem is particularly acute in high pressure applications.
  • EP 1 259 729 discloses a known fuel injector having a two part armature.
  • a fuel injector includes a pintle 1 having a valve head 2 at a distal end thereof, the pintle 1 being axially moveable within an injector body 3 between a closed position wherein the valve head 2 abuts a valve seat to close a spray aperture 4 in an injector tip and an open position wherein the valve head 2 is spaced from the valve seat to permit high pressure fluid to be ejected through the spray aperture 4.
  • a return spring 5 biases the pintle 1 to its closed position and a solenoid, comprising an electromagnetic coil 6 mounted within the injector body 3 and a two part armature mounted on the pintle 1, is selectively actuable to move the pintle 1 to its open position against the return spring 5.
  • the armature comprises an upper armature part 7 and a lower armature part 8, each armature part 7,8 being independently slidably mounted on the pintle 1 for limited axial movement with respect to the pintle 1 between fixed upper and lower stops 9,10 located on the pintle 1.
  • a compression spring 11 is located between the upper and lower armature parts biases the upper and lower armature parts away from one another whereby the spring 11 biases the upper armature part 7 against the upper stop 9 and the lower armature part 8 against the lower stop 10.
  • the lower armature part 8 is cup shaped, an outer region of the lower armature part 8 surrounding the upper armature part 7 to bring the lower armature part 7 into the magnetic field of the coil 6.
  • the two part armature of the present invention provides a three mass system (i.e. the pintle, lower armature part and upper armature).
  • the lower armature part 7 behaves like a downwardly biased single part armature while the upper armature part 8 behaves like an upwardly biased single part armature.
  • the two part armature arrangement provides three squeeze film damping gaps that can provide damping to eliminate valve bounce, namely a gap between the upper armature part 7 and the upper stop 9, a gap between the lower armature part 8 and the lower stop 10 and a gap between co-operating contact faces of the upper and lower armature parts.
  • Each of these gaps can be optimised to tune the opening and closing behaviour of the injector.
  • Fig 3 illustrates the movement of the valve head 2 of the pintle 1 when the solenoid is operated to deliver a predetermined amount of fuel to the combustion chamber of an internal combustion engine.
  • Fig 4 illustrates the movement of the upper armature part 7 of the injector during the same time interval while Fig 5 illustrates the movement of the lower armature part 8 during said time interval.
  • the solenoid remains energised for a period of time (between points C and D) to deliver a predetermined volume of fuel through the spray aperture 4.
  • the solenoid coil 6 is de-energised and the magnetic field generated by the solenoid coil rapidly breaks down.
  • the spring force of the return spring 5 now urges the pintle 1 and the upper and lower armature parts away from the coil 6 until the valve head 2 impacts the valve seat.
  • the greater strength of the return spring 5 compared to the compression spring 11 between the upper and lower armature parts and the inertia of the lower armature part retains the lower armature part 8 in contact with the upper armature part 7.
  • the upper and lower armature parts 7,8 continue to move downwardly until the lower armature part 8 impacts the lower stop 10 at point F.
  • the spring 11 then enhances the rebound of the upper armature part back up towards the upper stop 9 until the upper armature part returns to its at rest position at point G.
