Definitions
- control voltage can be adapted to changing operating conditions of the internal combustion engine, in particular changing state variables of the injection system, without additional sensory effort, which results in a fuel metering that is even more precise than in the prior art.
- the method enables a specific adaptation of the respective electrical control voltage for the metering of fuel for each injection valve or injector and for each combustion chamber of the internal combustion engine.
- the valve 101 has a piezoelectric actuator 104 for actuating a valve member 103 which is axially displaceable in a bore 113 of a valve body 107.
- the valve 101 also has an actuating piston 109 adjoining the piezoelectric actuator 104 and an actuating piston 114 adjoining a valve closing member 115.
- a hydraulic chamber 116 operating as a hydraulic transmission is arranged between the pistons 109, 114.
- the valve closing member 115 interacts with at least one valve seat 118, 119 and separates a low-pressure area 120 from a high-pressure area 121.
- An electrical control unit 112 which is only indicated schematically, supplies the control voltage for the piezoelectric actuator 104 depending on, in particular, the pressure level in the high-pressure area 121.
- the device shown in FIG. 3 for operating a common rail injection system of an internal combustion engine comprises a so-called release module 200, which in the exemplary embodiment can be activated by means of a push bit 205 provided by a control unit (not shown).
- a release module 200 which in the exemplary embodiment can be activated by means of a push bit 205 provided by a control unit (not shown).
- a control unit not shown.
- Possible further input variables of the release module are the current rail pressure and / or the current temperature of the piezo actuator.
- a rail pressure detection 210 is also arranged, the operation of which is triggered by the release module 200.
- a function module 215 for triggering the injection actuators according to the invention and subsequently adapting the trigger signals is also triggered accordingly.
- a further input signal 220 of the last-mentioned function module 215 is provided in the present exemplary embodiment by a speed signal evaluation module 225, which carries out an injection detection on the basis of a speed signal provided by the control unit.
- Typical drive voltage pulses are shown in FIG. 4 to illustrate the gradual increase in the drive voltage with a constant drive duration.
- the first voltage pulse 400 differs from the second voltage pulse 405 only in the voltage increment ⁇ U1 shown, the mean pulse duration ⁇ tl shown corresponding for both voltage pulses.
