Definitions
- the invention relates to a method and a device for actuating a solenoid valve, in particular for fuel injection into an internal combustion engine, the actuation phase of the solenoid valve being in a tightening phase during which a valve needle of the solenoid valve is opened by a first current flowing through a solenoid coil and in a holding phase is subdivided, during which the valve needle is held in the open state by a second, lower current flowing through the magnetic coil, and a booster phase is activated at least once at the beginning of the pull-in phase, in which a pulsed booster current from a booster capacitor charged to a high voltage is activated or another current source flows through the solenoid.
- the current reaches a starting current level I A after the current maximum IB OOS T caused by a first booster phase Bi with a large booster voltage UBO O ⁇ T, through which the valve needle of the solenoid valve can attract.
- the booster voltage UBOO ⁇ T. which is applied to the solenoid valve during the booster phase Bi is much larger than the battery voltage U_.
- the pull-in current level I A is regulated by repeatedly switching the battery voltage UBATT to the solenoid.
- the pull-in phase T A is first followed by a short free-running phase or a quick extinction, during which the current through the solenoid coil of the injection valve decreases very quickly, and reaches a holding current level IH, which is regulated to a desired level during the holding phase T H by repeated pulsing of the battery voltage UBATT , At the end, the holding phase T H is again followed by a free-running phase or quick-release, at the end of which the current through the magnetic coil is completely reduced.
- FIG. 2 now shows the case in which the valve needle cannot tighten during the tightening phase T owing to an insufficient battery voltage ⁇ BATT_: (FIG. 2) ⁇ UBATT (FIG. 1).
- ⁇ BATT_ battery voltage
- ⁇ UBATT ⁇ UBATT
- the level of the current through the injection valve should remain at a high level as much as possible during the entire opening movement of the valve needle in the tightening phase T A.
- a theoretically conceivable long booster phase that can be produced at this high current level over the entire pull-in phase does not make sense because of the high energy consumption from the internal booster capacitor.
- the booster phase serves to achieve a high current level as quickly as possible, with a large proportion of the booster energy being converted into eddy currents at the beginning of the pull-in phase T A.
- the booster phase Bi is interrupted under certain operating conditions in the prior art, the valve current is driven out of the battery and drops. This means that during the actual flight phase, that is the phase during which the valve needle moves, the magnetic force has already dropped from its maximum value. This means poor dynamics of the solenoid valve.
- this object is achieved in that several booster pulses are activated in succession during the actuation phase of the solenoid valve become. Basically, their timing within the control phase is freely selectable.
- a further booster impulse can be activated before or during the flight phase of the valve needle.
- a further booster pulse can be activated at the end or immediately after the valve needle's flight phase.
- a further booster pulse or a plurality of further booster pulses can be activated during the holding phase of the solenoid valve if the voltage of the supply battery is below a certain threshold voltage in this holding phase.
- the multiple boosters can reduce the energy or the maximum current of the individual booster pulses compared to a long individual booster with a very high current.
- a reduced peak current brings a lower load on the bonding pads for integrated circuits, the hybrid assemblies and a smaller storage capacity of the booster capacitor.
- the structure of the magnetic force can be varied freely in time by suitable selection of the times of the second and possibly third booster pulse. This leads to a reduction in eddy current formation, and de booster energy can be supplied depending on the time required for the solenoid valve. As a result, the tearing of the valve needle of the solenoid valve from the lower attachment point can be supported, the needle flight accelerated and the impact bouncer can be suppressed at the upper stop of the valve needle.
- the multiple booster can nevertheless raise the current level and thus ensure safe operation of the high-pressure injection solenoid valve.
- FIG. 1 shows, graphically in the form of a signal-time diagram, the usual course of the current and voltage through or on a solenoid coil of an injection valve in the case of a simple booster.
- FIG. 2 graphically shows the case which has also already been described, when the battery voltage becomes too low in the known method with simple booster.
- FIG. 3A shows, graphically in the form of a signal-time diagram, the current profile through a magnetic coil according to a first exemplary embodiment of the inventive method Double booster.
- FIG. 3B graphically shows the deflection of a valve needle during the activation phase of a high-pressure injection solenoid valve
- FIG. 3C graphically shows the current and voltage curve over the time of a second exemplary embodiment of the invention with triple booster.
- FIG. 3A shows a first exemplary embodiment of the method according to the invention, in which a double booster takes place at a relatively low battery voltage U BATT . That is, After the first booster pulse B_ activated at the beginning of the tightening phase T A , a further booster pulse B 2 ⁇ is activated, which, as a comparison with FIG. 3B showing the deflection X of the valve needle immediately makes clear, takes place during the flight phase f of the valve needle. As a result, the drop in the current through the solenoid shown in dashed lines in FIG. 3A is avoided, so that the control range of the pull-in current control is achieved despite the low battery voltage UBATT and a reliable opening of the valve is ensured.
- the double booster allows the current level to be kept high during the pull-in phase T A even with a low battery voltage U BA T T, and the valve can thereby be opened safely.
- FIG. 3C shows a second exemplary embodiment of the control method according to the invention, in which a third booster pulse B22 is activated immediately after the flight phase after the second booster pulse B 2 , which suppresses the bouncing p of the valve needle at the upper stop.
- a further booster pulse or a plurality of further booster pulses can be activated during the holding phase T H if, due to a high resistance in the circuit, the holding current I H can no longer be applied from the battery ,
- the control method shown in the figure is preferably by a device for controlling a solenoid valve for fuel injection into an internal combustion engine, the control phase of the solenoid valve in a tightening phase, during which a valve needle of the solenoid valve is opened by a first current flowing through a solenoid of the same and divided into a holding phase, during which the valve needle is held in the open state by a second, lower current flowing through the magnetic coil, and which activates a booster phase at least once at the beginning of the pull-in phase and thereby a pulse-shaped booster current from a booster capacitor charged to a high voltage or can flow from another current source through the solenoid, which has means for activating several booster pulses at selectable times within the control phase of the solenoid valve.
- This activation means may be connected with measuring means for measuring at least the suit current intensity X, the holding current I H, the battery voltage UBATT the supply battery, the booster voltage U B oos ⁇ and the booster current strength IBOOST-
- the method according to the invention enables in addition to Securing the operation of a high-pressure injector with low battery voltage by activating several booster pulses and thereby increasing the current level, so that safe opening or keeping of the high-pressure injector is ensured, more economical and variable use of the booster energy by the eddy current generation through the multiple booster is reduced and booster energy is made available depending on the time required.
- This supports the tearing of the valve needle from its lower stop point, accelerates the needle flight and suppresses the impact bouncer at the upper stop of the valve needle.
- the multiple booster can reduce the energy or the maximum current of the individual booster pulse, as a comparison of FIGS. 1 and 2 illustrating the conventional single booster shows. This can reduce the peak load on the bonding islands for the integrated circuits and the hybrid assemblies and the storage capacity of the booster capacitor.
