Definitions

  • the invention is based on a fuel injection valve according to the preamble of the main claim.
  • From DE 196 42 653 C1 is a method for metering Fuel with a fuel injector with the generic features of the main claim known.
  • the optimal each Setting parameter of the valve lift one Valve closing body and the duration of injection filed are the Injection map and taken from a control circuit for adjusting the valve lift and the injection duration for an operation of the internal combustion engine based. Then the smoothness of the engine is measured and with compared to an operating point specific setpoint.
  • From DE 40 05 455 A1 is a fuel injection valve with a piezoelectric actuator and one of the actuator with a valve lift actuated valve closing body, the with a provided on a valve seat carrier Valve seat surface cooperates to a sealing seat, known. In this case, to open the sealing seat of the actuator with a Voltage applied, which to close the sealing seat is switched off.
  • the fuel injection valve has a Fuel inlet on, about the fuel in the Fuel injection valve is passed. With a Fuel pump is the in the fuel injection valve conducted fuel with a fuel inlet pressure applied.
  • Fig. 1 shows an arrangement for explaining the inventive method for metering fuel with a fuel injection valve 1.
  • the Fuel injection valve 1 is here as inwardly opening Fuel injection valve 1 carried out, the method is suitable but also for an outside opening Fuel injection valve 1.
  • the fuel injection valve 1 used in the embodiment for direct injection of Fuel, in particular of gasoline, in a combustion chamber 2 a mixture-compacting, externally ignited Internal combustion engine 3 as so-called Gasoline direct injection valve.
  • fuel injector 1 is also suitable for other applications.
  • the supply of fuel into the fuel chamber 19 takes place via the fuel line 6 and the fuel pump 7.
  • the Fuel pump 7 is used to adjust the variable in the Fuel space 19 prevailing fuel inlet pressure.
  • the Fuel line 6 is connected to a connecting element 27 via a thread 28 with the valve housing 10 of the Fuel injection valve 1 connected.
  • the fuel pump 7 is with a fuel tank, not shown connected, from which they fuel in the fuel chamber 19 inflated.
  • the of the drive shaft 30 and the Abgasmeß worn 31 generated control variables are over the connections 32, 33 passed to the control unit 5 and in Processed as part of a motor control.
  • a Cylinder-specific control can be characterized the Set cylinder to each other; as can one Long - term drift of the injection behavior of the Correct fuel injector 1.
  • To at a solid fuel flow Q to the opening angle ⁇ can also vary the fuel input pressure of the Fuel can be varied by the fuel pump 7. It then results in a two-dimensional map, in which the Fuel flow Q and the opening angle ⁇ in dependence from the valve lift or the size of the control signal and the Fuel input pressure are shown.
  • To a desired pairing of fuel flow and opening angle (Q, ⁇ ) can then be the required valve lift h or the size of the control signal and the required Determine the fuel inlet pressure.
  • a control of the fuel injection valve 1 and the fuel pump 7 then let the fuel flow Q and the opening angle ⁇ set independently.
  • the control unit 5 with a connection (50, Fig. 1) with the fuel pump 7 connected.
