Definitions

the present invention relates to an ignition device for an internal combustion engine, in particular for a gas engine, with a control device and with an ignition coil which can be fed by a voltage source on its primary side.
the ignition coils of the generic ignition devices are transformers, on the secondary side of which the high voltage is applied to the spark plug. During operation of these ignition coils power is transferred from the primary side to the secondary side.
the object of the invention is to make this as effective as possible and to avoid destruction or impairment of the components of the ignition device even with large power requirements.
control device is provided to interrupt or reduce the voltage applied to the primary side of the ignition coil voltage when an amount of magnetic induction B on the primary side of the ignition coil exceeds a predetermined maximum value.
the limitation of the amount of magnetic induction on the primary side prevents too high currents from flowing on the primary side, which could lead to impairment or destruction of the primary components of the ignition device.
this type of limitation also ensures an effective power transmission across the ignition coil, since far below the saturation of the ignition coil relatively small changes in the primary-side current cause relatively large changes in the amount of magnetic induction B.
the predefinable maximum value of the amount of magnetic induction B is an upper limit of a working range in which there is an at least approximately linear relationship between the amount of the magnetic induction B and the primary-side current.
Advantageous embodiments provide for an indirect determination or evaluation of the magnetic induction B on the primary side of the ignition coil.
a first variant is characterized in that the control means determines the amount of magnetic induction B on the primary side of the ignition coil indirectly via an evaluation of a duration of on-time and off-time, the voltage of the period being determined during the on-time Voltage source is applied to the primary side of the ignition coil and during the off time (s) the voltage of the voltage source is not applied to the primary side of the ignition coil.
the ignition device has a primary current measuring device and the control device determines the amount of the magnetic induction B on the primary side of the ignition coil indirectly via an evaluation of the magnitude of the primary-side current.
the control principle described below can be used to control a modulated high-voltage capacitor ignition (HCC).
the modulated HKZ is based on the idea of gradually feeding the ignition energy of the capacitor to the ignition coil.
This can basically be controlled or regulated.
the controlled variant is realized and described below.
the primary side of the ignition coil is switched to the supply voltage depending on the condition of the spark on the secondary side.
An advantage of this system lies in the time extension of the spark while controlling the Zündfunken characterizing. Burning times, preferably up to 5,000 microseconds can be achieved easily with this system.
a high voltage supply up to 40 kV (kilovolts) is often required.
the burn time is typically set by the controller between 100 and 1200 microseconds.
the spark is characterized by an adjustable specification of the combustion current setpoint I rated (see FIG. 2).
the control device must be the primary-side voltage supply of the ignition coil so trigger that the predetermined characteristic of the spark or the desired course of the secondary-side current I rated is achieved as well as possible.
Combustion concepts and internal combustion engines with high efficiency also have very high turbulence in the combustion chamber. Due to these turbulences, the spark of a secondary side triggered by an ignition spark plug is spatially extended and it can lead to premature extinction. To prevent a misfire in the combustion chamber due to insufficient burning time, the spark must be restored in the shortest possible time.
the necessary ignition voltage can be quite close to the high voltage supply of the ignition coil. In order to generate a new spark as quickly as possible, it should be taken into account that residual energy is still present in the resonant circuit of the high-voltage circuit, ie on the secondary side of the ignition coil when the ignition spark goes out. Therefore, to produce the spark, it is necessary to select a timing that positively utilizes the existing energy in the system.
control device 12 After an interruption of the primary-side voltage and / or power supply of the ignition coil during an ignition process or following the fall of the primary-side voltage and / or the primary-side current I pri by the ignition coil 3 below a predetermined threshold will switch on during the ignition, the primary-side voltage and / or current supply of the ignition coil 3 or adjusts it above the threshold value if the thus induced secondary-side current acts in the direction of the preferably immediately previously determined course of the secondary-side current I sek I sek.
Fig. 1 shows schematically a control principle for an inventively modulated ignition device, here in the form of a high voltage capacitor ignition.
the ignition coil 3 is a well-known transformer
the primary side is a DC voltage source, which here consists of the DC-DC converter 1 and a capacitor 2 connected in parallel thereto.
the control 13 switch 4 is provided on the primary side of the controlled by the control device 12 via the control 13 switch 4 . This can be designed as a semiconductor switch.
the switch 4 has at least one first switching state, in which the voltage of the voltage source is applied to the ignition coil 3, and at least one second Switching state in which the voltage of the voltage source is not applied to the ignition coil 3, on.
a freewheeling diode 18 is connected in parallel to the primary-side winding of the ignition coil 3. This is used for de-energizing the primary side 15 described below in the switched-off state of the voltage source when the switch 4 is open.
an additional ohmic resistor 19 can also be connected in series with the freewheeling diode 18. This means a loss of energy.
the resistor 19 and the achieved attenuation of the primary side 15 in the de-energizing faster reconnection after the extinction of a spark is possible.
the switching on and off of the voltage source 1, 2 takes place in this embodiment so only through the switch 4.
This value I pri is forwarded to the control device 12.
a shunt 6 for the current in the spark in series On the secondary side 16 is connected to the corresponding winding of the ignition coil 3, a shunt 6 for the current in the spark in series.
a secondary current measuring device 7 and a secondary voltage measuring device 8 are provided.
the secondary-side current I sec measured by means of the secondary current measuring device 7 is evaluated in this exemplary embodiment by means of the polarity evaluating device 9 with respect to its polarity and by means of the current intensity evaluating device 10 with respect to its amplitude or current intensity. It is provided in the embodiment shown that the evaluation of the amount, ie the current strength of the secondary-side current I sec limited to whether this is greater than or equal to a predetermined minimum value or not. This will be explained further below with reference to FIG. 2 in detail. As a rule, the nominal fuel flow rate I rated will be used as a predefinable minimum value.
the values determined by the polarity evaluation device 9 and the current intensity evaluation device 10 do not give singular single values but the course of the Secondary current I sec again and this to the controller 12 on.
the same can also apply to the secondary-side voltage U sec measured by means of the secondary voltage measuring device 8. This is evaluated with the high-voltage evaluation device 11, which in turn forwards the voltage information to the control device 12.
the control device 12 activates the primary-side switch 4 and thus regulates the current and voltage supply of the primary side 15 of the ignition coil 3.
a course of an ignition process is shown based on various parameters, during which the spark breaks off and is rebuilt.
the operation of the control device will be explained in more detail below with reference to the individual phases of this ignition process.
the control passes through the phases of ionization Ph1, current control Ph2, de-energization Ph3 and synchronization. The latter is realized at the transition between Ph3 and subsequent Ph1.
U sec shows the secondary voltage curve.
I sec shows the course of the measured secondary current.
I rated shows the setpoint course of the secondary-side current and thus preferably also the course of the minimum value on the basis of which the Strombynausute worn 10 decides whether the measured secondary side current I sec reaches or exceeds the target current value or below.
FB1 shows the evaluation result of the current intensity evaluation device 10.
FB1 assumes the value 1 if I sec is greater than or equal to I rated . In the other cases, FB1 assumes the value 0.
FB2 shows the result of the polarity evaluation device 9. If the measured secondary side current I sec is in the positive range, FB2 assumes the value 1. If the secondary-side current is negative, FB2 assumes the value 0.
T Switch shows the course of the control signal of the control device 12 to the switch 4. If this 1, then the switch 4 is closed and the voltage or power supply is applied to the primary side of the ignition coil 3. If the drive signal is 0, then the switch 4 is opened, whereby the voltage and power supply from the primary side 15 of the ignition coil 3 is disconnected.
the graph I pri shows the course of the primary-side current during the ignition process. All graphs thus represent the time course of the parameters.
the current setpoint of the secondary-side current I rated is adjustable via the control device 12 and is supplied to the current intensity evaluation device 10 in this exemplary embodiment for the determination of FB1.
the Strombutnauslus pain 10 may be designed for this purpose as a comparator.
the setpoint curve of the secondary-side current I rated can be set to different values by the control device 12, preferably both with respect to the burning time and with regard to the current intensity.
the control device 12 is first switched to the ionization phase Ph1.
This is a turn-on interval ⁇ t an1 in which the high voltage is built up, which is needed for the generation of the spark.
.DELTA.t an1 it is preferably provided that, when the switch 4 is closed, the voltage of the voltage source 1, 2 is permanently applied to the primary side 15 of the ignition coil 3 in full height and at least for the predefinable time duration .DELTA.t an1 .
the ignition coil 3 is thus connected on the primary side to the supply voltage on the primary side during the entire ionization phase or during the entire on-time interval.
the ionization phase for a fixed set time, which is necessary to generate the high voltage and thus the secondary side spark is connected.
the ionization phase can optionally also be switched off when the high voltage output by the ignition coil is exceeded in comparison with a limit value.
the control device 12 monitors the secondary-side current I sec via the secondary current measuring device 7 and / or the secondary side of the ignition coil 3 output voltage U sec via the secondary voltage measuring device 8 and the primary-side voltage supply of the ignition coil 3 during the Anschaltzeitintervall .DELTA.t interrupts when the secondary-side current I sec and / or the voltage U sec output by the ignition coil on the secondary side exceeds (exceeds) a specifiable limit value (e). This option protects the system from destruction if the spark plug, spark plug plug, or other malfunction is defective.
the spark is spatially extended, which increases the voltage at the spark plug and requires more energy to be supplied to the spark plug.
the current setpoint I rated can no longer be achieved and the spark must be deliberately extinguished by initiating the phase of de-energization Ph3.
the requirements of the internal combustion engine can be met especially well if the rated fuel input I rated during the spark can be changed.
the phasing phase Ph3 is needed in two cases. On the one hand, this can be the case if the spark unintentionally breaks off during the planned ignition process and has to be rebuilt. On the other hand, deenergizing may be necessary if the magnetism level or the magnetic induction B on the primary side 15 of the ignition coil 12 becomes too large.
FIG. This shows the relationship between the current strength of the primary-side current I pri and the amount of magnetic induction B on the primary side 15 of the ignition coil 3.
the amount of magnetic induction B with increasing current I pri in reaches the area of saturation.
the control device 12 the voltage applied to the primary side 15 of the ignition coil 12 interrupts or reduces when the amount of the magnetic induction B on the primary side 15 of the ignition coil 12 exceeds a predetermined maximum value B max .
the predefinable maximum value B max of the amount of the magnetic induction B is the upper limit of a working range 17 in which there is an at least approximately linear relationship between the amount of the magnetic induction B and the primary-side current I pri .
the predefinable maximum value B max is favorably arranged far below the saturated region of the ignition coil 3.
two current changes ⁇ I 1 and ⁇ I 2 of primary-side current in Fig. 3 shown which are required to have the same change in the magnitude of the magnetic induction B (amount of .DELTA.B 1 is the same amount of .DELTA.B 2) cause.
the comparatively small current change ⁇ I 1 is sufficient due to the more or less linear relationship between the primary current I pri and the amount of the magnetic induction B.
a considerably larger current change ⁇ I 2 must be used.
the magnetism level or the magnetic induction B is an image of the height of the primary-side current I pn .
a limitation of the amount of the magnetic induction B thus avoids destruction of the primary-side components through high currents. Therefore, it is preferably provided that when the maximum value B max is exceeded, the ignition coil 3 is de-energized in order to reduce the magnetism level or the amount of the magnetic induction B.
the magnetism level can be determined by evaluating the switch-on and switch-off times of the switch 3.
the control device 12 determines the amount of the magnetic induction B on the primary side 15 of the ignition coil 3 indirectly via an evaluation of a duration of switch-on time (s) and switch-off time (s), wherein during the switch-on time (s) voltage the voltage source is applied to the primary side 15 of the ignition coil 3 and during the off-time (s) the voltage of the voltage source is not applied to the primary side 15 of the ignition coil 3.
a useful variant provides that the maximum value is a predefinable period of time and the control device compares this time period with the sum of the switch-on times, preferably from the beginning of an ignition process minus the sum of the switch-off times, preferably from the beginning of the ignition process.
the ignition device has a primary current measuring device 14 and the controller 12 determines the amount of magnetic induction B on the primary side 15 of the ignition coil 3 indirectly via a rating of the primary-side current I pri .
the maximum value B max is substituted by a predefinable maximum current value, wherein the control device 12 compares this with the amount of the primary-side current I pri .
the primary-side voltage supply is switched off by opening the switch 4 until the magnetism level has been lowered to an acceptable value.
the control device 12 following an interruption or a reduction of the voltage applied to the primary side 15 of the ignition coil 12, the control device 12 only permits or restarts the voltage again when the amount of the magnetic induction B on the Primary side 15 of the ignition coil 12 below the predetermined maximum value B max or corresponding maximum values of the above-mentioned replacement parameters or a predetermined reclosing setpoint value.
the restart setpoint value can also be selected to be lower than the maximum value used for the evaluation depending on the variant embodiment.
the course of the primary-side current I pri is shown as the lowest graph. This shows the general tendency of the increase of the primary-side current, while in the phase of the de-excitation Ph3 a decrease of the primary-side current I pri can be seen.
the control device 12 following an interruption of the primary side voltage and / or power supply of the ignition coil 3 during an ignition process or following the fall in the primary-side voltage and / or the primary-side current I pri by the ignition coil 3 below a predetermined threshold during the ignition, the primary-side voltage and / or power supply of the ignition coil 3 only turns on or above the threshold regulates if the induced secondary side current I sec in the direction of, preferably immediately, predetermined course of the secondary current I sec acts.
the switch 4 should therefore not be turned on when the secondary current I sec is negative.
Switching is advantageously carried out only in or after the time t n , in which the polarity of the secondary current changes and thus the secondary side induced current via the connection of the primary-side voltage supply acts in the direction of the predetermined course of the secondary-side current I sec .
the start of the now following ionization phase Ph1 or of the on-time interval ⁇ t an2 is thus synchronized with the secondary-side profile of the current.
the switch 4 remains closed until the desired high voltage supply is reached.
the starting time t n of the ionization phase is determined from the monitoring of the polarity of the secondary-side current I sec (see also FB2 from FIG. 2). Since the natural frequency of the ignition device is determined by its components, this is known. Conveniently, it can therefore be provided that the control device 12, the primary-side voltage and / or power supply of the ignition coil 3, preferably immediately after a predetermined time offset following a polarity change or zero crossing of the secondary side current I sec reconnects or regulates the pre-determinable threshold , wherein preferably the predetermined time offset corresponds substantially to a quarter of the natural period, preferably the secondary side 16, the ignition device. Accordingly, the ionization phase begins with a delay of one quarter of the natural period of the system after the secondary current I sec enters the positive region.
the ionization phase is prevented from being interrupted by the maximum value of the amount of magnetic induction B being reached. It is provided that the ionization phase can only be started when the magnetization level or the amount of magnetic induction B on the primary side 15 of the ignition coil is low enough at the beginning. If this is not the case, the system must be de-energized (phase Ph3) until the required low magnetization level is reached.
the ionization phase for the reconstruction of the spark can thus be started preferably only when the magnetization level and the synchronization condition in the resonant circuits are met.
switch-on times of the switch 4 are summed during the given burning time. If the summed on time of the switch 4 exceeds a predetermined limit value, the ignition process is aborted. This monitoring is conveniently independent of the magnetization level.
the quality of the ignition process is usually assessed based on the actual spark duration of the spark.
the burning time is measured between the attainment of the predetermined nominal fuel flow value I rated up to the zero value of the secondary current I sec . If the spark extinguishes during the given burning time and this is rebuilt, the measurement is restarted when the preset current set point is reached and stopped again at the zero value of the secondary current I sec . The measured values of the individual measuring processes are summed up. After completion of the ignition process, the combustion duration measurement is stopped and the measured value is evaluated. For the measurement or detection of misfires, the combustion duration measurement is reset if the measurement is shorter than the ionization phase from the attainment of the desired fuel burn value to the zero value of the secondary current I sec . In this case, no spark has been generated in the first ionization phase. This circumstance is considered a mistake or a dropout.
a capacitive current can build up in the secondary circuit due to the capacitive loading of the high voltage cabling and the spark plug. This current flows independently whether a spark is generated at the spark plug 5 or not.
the fuel flow setpoint I rated is in the ionization phase chosen so that the value must be safely exceeded. The reaching of the combustion current setpoint is queried shortly before the end of the ionization phase. If the secondary current I sec is not high enough at this time, then there is a hardware error in the system.
