Definitions
- the invention is based on a Fuel injection device for an internal combustion engine according to the preamble of claim 1.
- Such a fuel injector is through the DE 198 35 494 A1 known.
- This fuel injection device has a fuel injection valve, with a Injection valve member, through which at least one Injection opening is controlled.
- the injection valve member is of that in a pressure room of the Fuel injection valve prevailing pressure in one Opening direction acted upon against a closing force.
- a high-pressure fuel pump generated by a Cam is driven in a lifting movement. It is a by a piezoelectric actuator actuated control valve provided by an electrical control device is controlled and by the one connection of the Pressure chamber is controlled with a discharge space.
- the Control valve has a control valve member, on which the Actuator acts via a hydraulic coupler to this between an open position and a closed position To move position.
- the control valve member in his closed position, so is the pressure chamber of Relief space separated and it may be in this Build up high pressure for a fuel injection.
- the Time of reaching the closing position of the Control valve member is thus of great importance for the Control of fuel injection. Since that Control valve member from the actuator, however, through the coupler is disconnected, is no information about this date available. In addition, for a proper Function of the control valve also a complete filling required of the coupler.
- the fuel injection device with the Features according to claim 1 has the advantage that the function of the control valve can be monitored.
- a pressure on, even after Completion of the charging process on the actuator and back in this with disconnected power supply one for the Pressure conditions in the coupler and consequently also for the Implementation of the drive voltage in the stroke of Control valve member generates characteristic piezoelectric voltage.
- the voltage between the electrical connections on the piezoelectric actuator can thus without the requirement another sensor as a measurement parameter for the Valve behavior are used.
- the measured Voltage can be used according to claim 2, to the time of reaching the closing position of Control valve member to determine.
- the course of the tension can as indicated in claim 3 to the occurrence of a Minimums are monitored in the course of the curve.
- the pressure in the Coupler takes after charging the actuator in the temporal course first off, as the actor after completion Charging reaches approximately its full stroke has, while the control valve member is at this time still moved to its closed position and the coupler thus relaxed. Once the control valve member the Has reached closing position and due to a Bouncing towards its open position moved back, but there is a compression of the coupler medium, resulting in an increase in the Terminal voltage noticeable.
- the voltage can also be used to detect the Be filled state of the coupler, since the Pressure curve in the coupler depends on the filling state and thus also effects on the tension Has.
- the test drive provided according to claim 8 allows verification of the function of the control valve before fuel injection, with correction values can be determined in the following Fuel injection can be used. Of the time interval between the determination of the correction value and the control of the control valve to Fuel injection is thus very low, so that the Fuel injection can be done with high accuracy.

- the hydraulic coupler 57 in turn acts on one in a connection channel 64 guided adjusting piston 65, at the end of the coupler 57th opposite end of the control valve member 56 is arranged. It can be provided that the control valve member 56 with two Valve seats cooperates, which in a valve chamber 66 are formed, in which the control valve member 56 is arranged is.
- the control valve member 56 is located in a first End position, which is a tensionless rest position of Actuator 58 corresponds to a first valve seat 68 in Valve space 66 on. In a second end position, the one maximum activation of the actuator 58 corresponds and a Closed position of the control valve member 56 is located Control valve member 56 at a second valve seat 70 in Valve chamber 66 and closes this. It can also be provided that the control valve 54 as double-switching valve is formed, wherein the Control valve member 56 when it is in contact with one of both valve seats 68,70 is respectively closed and only in an intermediate position between the two Valve seats 68,70 is open.
- valve chamber 66 opens between the two valve seats 68,70 a connection 71 to the discharge room.
- valve chamber 66 On the second valve seat 70, the valve chamber 66 a Connection with the pump working chamber 20 on. If that is Control valve member 56 in its first end position in Appendix is located on the first valve seat 68, so is the compound of Valve space 66 to the pump working chamber 20 via the second Valve seat 70 is opened, so that the pump working chamber 20 with connected to the discharge room and is not in this Can build up high pressure.
- connection 71 of the Valve chamber 66 with the discharge space may be a Throttle 67 may be provided.
- Control valve member 56 in its second end position and thus its closed position in contact with the second valve seat 70th is the connection of the valve space 66 to Pump working chamber 20 via the second valve seat 70th closed, so that the pump working chamber 20 from Relief space is separated and in this high pressure can build, according to the delivery stroke of the pump piston 18.
- the date of reaching the closing position of Control valve member 56 thus determines the beginning of Fuel injection and the duration of the arrangement of Control valve member 56 in its closed position determines the Fuel quantity injected.

For this the voltage signals become one associated with the voltage measuring device 72 Differentiator 76 is supplied. The educated there differentiated signals are subsequently sent to the Diagnostic device 74 transmitted. In both alternatives is derived from the time course of the tension between the Terminals 61 of the actuator 58 in the diagnostic device 74th upon reaching the closed position of the control valve member 56 closed.
- control valve member 56 Once the control valve member 56 its closed position has reached and due to a bounce in the direction however, it moves back to its first end position a compression of the medium in the coupler, the analogously in an increase in the voltage between the Make connections 61 of the actuator 58 noticeable.
- the im Voltage curve occurring minimum thus identifies the Time at which the control valve member 56 his Has reached closing position.
- Detecting the timing of the closing of the control valve 54 can provide correction values for control parameters Control device 53 are obtained, which for a subsequent fuel injection can be used and by the accuracy of the fuel injection in terms of timing of fuel injection and Fuel injection quantity can be improved.
- the test control of the Control valve 54 is preferably carried out during a Time interval, during which also the filling of the Pump workspace 20 during the suction stroke of the pump piston 18 with Fuel as well as the removal of fuel from the Pump work space 20 to terminate the Fuel injection with open control valve 54 is not or is affected as little as possible.
- the reduction of the voltage also depends on particularly pronounced degree of filling in the coupler 57 from.
- fully filled coupler 57 is a comparatively pronounced voltage dip of, for example, about 50V detectable.
- this effect is only partial filled coupler 57 significantly lower, the For example, voltage drop is only about 15V.
- a Diagnosis statement formed by after the loading phase of Actuator 58 the voltage is measured. After a predefinable Waiting time of about 0.25 ms, for example, becomes the voltage measured again. Then the difference of both measured values formed and compared to a limit. It can do that a fixed limit may be specified, for example can be about 30V. Alternatively, however, a Operating point dependent limit from a by previous Obtained in a data storage module 78 stored map are based. The waiting time is so selectable that the measurement of the voltage immediately before a subsequent tax intervention, namely before a further increase in the voltage takes place.
- the Setpoint is chosen such that, despite the detected incomplete filling of the coupler 57 after driving the intended stroke of the Control valve member 56 results.
