Definitions
- the invention relates to a method for production a sequence of high voltage ignition pulses as well as a High-voltage ignition device according to the preamble of claim 8.
- this measuring line can be used to measure the Spark current can be used. This results in an inexpensive and robust solution to the Control of the recharging process by the control unit.
- FIG. 1 shows a high-voltage ignition device 1, an ignition energy store 2, a control unit 3 and comprises a switching element 4.
- the high voltage igniter 1 places on a spark gap 5 electrical energy for generating a high-voltage spark ready.
- the spark gap 5 is formed on an ignition spark generating means 6, that should preferably be implemented as a spark plug can.
- the ignition energy store 2 is in a preferred embodiment formed as an inductor, that is Ignition coil 7 realized that a primary winding 8th and has a secondary winding 9.
- Ignition coil 7 realized that a primary winding 8th and has a secondary winding 9.
- the ignition spark generating means 6 On the secondary winding 9 is the ignition spark generating means 6 connected, with another in this circuit Interference suppressor 10 and a so-called EFU diode 11 (switch-on spark suppression) arranged are, the anode with the spark gap 5 and their Cathode are connected to the secondary winding 9.
- EFU diode 11 switch-on spark suppression
- the primary winding 8 has one winding end at a supply voltage U B , which is, for example, the battery voltage of an on-board battery of a motor vehicle.
- U B a supply voltage
- the other winding end of the primary winding 8 can be connected to ground via the switching element 4.
- the supply circuit for the primary winding 8 is opened or closed.
- the switching element 4 is closed, the ignition energy store 2 is charged. After the ignition energy store 2 has been charged, the stored ignition energy is dissipated via the spark gap 5 by opening the switching element 4 and the ignition energy store 2 is thereby discharged.
- the control device 3 has a voltage measurement input 14, which is connected to a voltage tap 15, which is located in the primary-side circuit between the primary coil 8 and the switching element 4, in order to be able to measure the so-called clear timer voltage of the ignition energy store 2. Furthermore, the control device 3 has a current measurement input 16, which is connected to a current tap 17 of the switching element 4. The primary current I P is measured via this current measurement input 16, at least during the charging process of the ignition energy store 2. In addition, the control unit 3 includes a determination device 19 which determines the state of charge of the energy store 2 at least during the generation of ignition sparks.
- the determination device has a current measurement input 20, which is connected to a winding end of the secondary winding 9, so that the spark current I F can be measured during the ignition spark generation.
- a measuring resistor 21, also referred to as a shunt is connected to the connecting line between the current measuring input 20 and the secondary winding 9 with its one connection, the other connection of the measuring resistor 21 being connected to ground 18.
- control unit 3 has a control input 22, to which a standing voltage U E can be applied, which can be output by a switching device.
- the mode of operation of the high-voltage ignition device 1 is explained below on the basis of FIGS. 1 and 2a to 2c: when the control input 22 is activated, the control voltage U E is present for a period of time t 0 to t E (FIG. 2c). Thereupon the control device 3 controls the switching element 4, so that the supply circuit for the primary winding 8 is closed and the primary current I P increases from the time t 0 .
- the current I P changes depending on the state of charge of the ignition energy store 2.
- the switching element 4 When a predeterminable value I P, IGNITION is reached at the time t 1 , the switching element 4 is opened again via the control unit 3, so that the subsequent discharge process of the ignition energy store 2 generates the spark current I F ( Figure 2b) at time t 1 rises, whereupon the ignition spark on the spark gap 5 burns. By progressive discharge of ignition energy 2 of the spark current I F decreases.
- a predeterminable trigger value I TR of the spark current I F which is detected by the determination device 19, is reached, the switching element 4 is closed again via the control unit 3 and a recharging process of the ignition energy store 2 is started at time t 2 .
- the charging process is carried out again until the specific value I P, IGNITION for the primary current is reached at time t 3 , whereupon the switching element 4 is opened again via the control unit 3, so that a subsequent ignition spark at the spark gap 5 at the time t 3 by the discharging process ignites that burns until the spark current I F has dropped back to the trigger value I TR at time t 4 , whereupon the switching element 4 is closed again and a further charging process of the ignition energy store is carried out until the value of the primary current I P again Value I P, IGNITION reached at time t 5 .
- the ignition store 2 is discharged again, which in turn generates an ignition spark at the time t 5 on the spark gap 5.
- control voltage U E is no longer present at the control input 22 at the time t E , so that the control unit 3 does not close the switching element 4 again and the ignition spark burns out completely. It is thus readily apparent that, depending on the activation time t 0 to t E, an initial spark can be generated at time t 1 , at least one or more subsequent sparks can be generated in time period t 2 to t 4 and a final ignition spark is generated at time t 5 , which burns out can.
- the switching element 4 for a charging process of the ignition energy storage device 2 is only closed when the ignition spark current I F triggers the trigger value I TR for a specific one Time period, for example 20 ⁇ s to 80 ⁇ s, falls short, so that current peaks are virtually filtered out and are not taken into account when driving the switching element 4.
- the trigger value I TR is less than the maximum current I F, max and can be, for example, 0.3 to 0.7 times the maximum ignition current I F, max .
- This trigger value I TR can therefore be varied, preferably as a function of at least one operating parameter of the internal combustion engine.
- the speed and / or the load of the internal combustion engine can be used for this.
- a characteristic curve field is available which contains several characteristic curves, so that the trigger value I TR can be selected as a function of these operating core lines of the internal combustion engine. Changing the trigger value I TR also changes the duration of a single spark, so the number of sparks for a spark sequence can be changed.
- FIG. 3 shows a second exemplary embodiment of a high-voltage ignition device 1, in which the determination device 19 is embodied in a switching unit 27 connected upstream of the control unit 3, which includes a switching unit 28, which is connected on the output side to the control input 22 of the control unit 3 and the control voltage U E provides for the control unit 3.
- the control voltage U E is provided in a pulse-like manner in accordance with FIG. 4a, specifically as a function of the spark current I F. If this spark current I F reaches the trigger value I TR (FIG. 4c), a control voltage pulse U E is again applied to the control input 22, so that the control unit 3 closes the switching element 4 until the primary current I P has the ignition value I P, IGNITION (FIG.
- the current measurement input 20 is tapped between a Zener diode 29 and the measuring resistor 21, the Zener diode 29 being switched in the forward direction for the spark current I F.
- the connecting line between the secondary winding 9 and the Zener diode 29 is passed on to an ion current measuring device 30, with which the ion current in the combustion chamber can be measured during spark breaks, for example in order to be able to assess the knocking behavior of the internal combustion engine.
- the same or equivalent parts in FIGS. 3 and 4 as in FIGS. 1 and 2 are provided with the same reference numerals. In this respect, reference is made to their description.
- the adjustment of the discharge time of the ignition energy storage can also meet the conditions in the secondary circuit of the ignition energy storage 2 and the ignition spark generating means 6 can be adjusted so that also tolerances of resistors 12, 10 and 13 in Secondary circuit can be compensated.
