Definitions

  • the present invention relates generally to systems for generating plasma between two electrodes of a spark plug, used in particular for radiofrequency ignition control of a gaseous mixture in combustion chambers of an internal combustion engine.
  • plasma generation circuits incorporating coils-candles are used to generate multi-filament discharges between their electrodes, to initiate the combustion of the mixture in the chambers of combustion of the engine.
  • the multi-spark plug is described in detail in the following patent applications in the name of the Applicant FR 03-10766 , FR 03-10767 and FR 03-10768 .
  • Another example of a known system is described in US Patent 5,655,201 .
  • Such a coil-plug is conventionally modeled by a resonator 1, whose resonant frequency F c is greater than 1 MHz, typically close to 5 MHz.
  • the resonator comprises in series a resistor R, an inductance L and a capacitance C. Ignition electrodes 10 and 12 of the coil-plug are connected across the capacitor C.
  • the amplitude across the capacitor C is amplified, making it possible to develop multi-filament discharges between the electrodes of the candle, on distances of the order of one centimeter, at high pressure and for peak voltages below 30 kV.
  • branched sparks These are referred to as branched sparks, insofar as they involve the simultaneous generation of at least several lines or ionization paths in a given volume, their branches being moreover omnidirectional.
  • the control of the supply of such a coil-plug requires the use of a power supply circuit, capable of generating voltage pulses, typically of rise time of 100 ns, and amplitude of the order of 1 kV, at a frequency intended to be very close to the resonant frequency of the radiofrequency resonator of the coil-candle.
  • a power supply circuit capable of generating voltage pulses, typically of rise time of 100 ns, and amplitude of the order of 1 kV, at a frequency intended to be very close to the resonant frequency of the radiofrequency resonator of the coil-candle.
  • the greater the difference between the resonance frequency of the resonator and the operating frequency of the generator the higher the resonator overvoltage coefficient (ratio between the amplitude of its output voltage and its input voltage) is high.
  • Such a feed circuit is schematically represented at figure 2 . It conventionally uses a so-called “Class E power amplifier” assembly. This type of DC / AC converter makes it possible to create the voltage pulses with the aforementioned characteristics.
  • the amplifier 2 comprises switch M for controlling the switches across the resonator 1, made according to this example in the form of a power MOSFET transistor.
  • a control device 5 generates and applies a control signal V1 to a control frequency on the gate of the power MOSFET M, via a control stage 3 shown schematically.
  • the latter is activated by the different ignition commands and is in the form of control pulse trains at the control frequency.
  • a parallel resonant circuit 4 is connected between an intermediate voltage source Vinter and the drain of the transistor M.
  • This circuit 4 comprises an inductance Lp in parallel with a capacitance Cp.
  • the parallel resonator transforms the intermediate voltage Vinter into an amplified voltage Va (illustrated in FIG. figure 5 ), corresponding to the intermediate voltage multiplied by the overvoltage coefficient of the parallel resonator.
  • This amplified voltage is supplied on the drain of the transistor M, which is also connected to the input of the resonator 1.
  • the transistor M therefore acts as a switch and applies (respectively blocks) the voltage Va to the input of the resonator 1 when the control signal V1 is at the logic high (respectively low).
  • the transistor M thus imposes a switching frequency, determined by the control signal V1, which is sought to make as close as possible to the resonant frequency of the coil-plug connected at the output (typically 5 MHz), in order to maintain and maximize the energy transfer between the parallel resonator 4 and the series resonator 1 forming the coil-candle.
  • This phase of energy transfer from the power stage formed by the amplifier to the resonator of the coil-plug must be performed at the resonance frequency of the resonator, to ensure a good performance. Indeed, if the transistor M imposes a different switching frequency of the resonant frequency of the coil-candle, the energy transfer is degraded, because of the narrow bandwidth of the series resonator used for the candle coil .
  • each combustion chamber is equipped with a coil-candle as described above to initiate, on command, combustion.
  • the present invention aims to overcome this disadvantage, by allowing to control a plurality of coils-candles through the same and single amplification channel.
  • each plasma generating circuit comprises a resonator and each resonator comprises a distinct resonance frequency.
  • each plasma generation circuit comprises a resonator, each resonator having an identical resonance frequency, and at least one of the plasma generation circuits further comprises means for shifting the resonance frequency of its resonator.
  • the frequency shift means comprise an impedance matching circuit arranged in series between the output of the supply circuit and the resonator.
  • the impedance matching circuit comprises an inductance.
  • the impedance matching circuit is constituted by an impedant connecting cable ensuring the connection between the output of the supply circuit and each resonator, the length of the portion of cable between the resonators defining the frequency offset. between the resonators.
  • each plasma generation circuit is adapted to achieve ignition in one of the following implementations: controlled ignition in a combustion engine cylinder, ignition in a particle filter, ignition decontamination in an air conditioning system.
  • the present invention therefore aims at controlling a plurality of coil-type plasma generation circuits, using a single amplification channel, in other words by using a single power supply circuit of the class E power amplifier type as previously described. to the figure 2 , for selectively supplying the plurality of plasma generation circuits connected in parallel at the output of this single supply circuit.
  • the principle on which this particular assembly is based consists in exploiting, at the level of the high voltage and high frequency control generated by the supply circuit, the resonance frequency specific to each plasma generation circuit connected at the output of the supply circuit. .
  • each of these plasma generating circuits has a resonant frequency well separated from the others. This is indeed to avoid overlapping resonance frequency resonator domains forming each plasma generation circuit and thus to overcome the problems of multiple simultaneous ignitions.
  • the resonant frequency difference between the plural plasma generation circuits connected in parallel at the output of the single supply circuit must preferably be at least equal to a multiple of the bandwidth of each resonator. For example, it may be possible to shift the resonance frequency of each plasma generating circuit relative to each other by a value equal to two or three times the bandwidth of each circuit.
  • a first way to do this is to use for each plasma generation circuit a coil-candle, as modeled at the figure 1 , different by construction, so that the coils-candles used have sufficiently distinct resonant frequencies in accordance with the principles outlined above.
  • each plasma generation circuit consists of a resonator as shown in FIG. figure 1 and where each resonator has a distinct resonant frequency, however, is not optimal for integration into an industrial process.
  • a preferred embodiment for carrying out the resonance frequency shift between the plurality of plasma generation circuits to be controlled consists in using identical coil-plugs, the resonators of which model them have identical resonance frequencies, and to associate each resonator means for shifting its resonance frequency.
  • the resonance frequency shifting means of a plasma generating circuit comprises an impedance matching circuit 14, arranged to be arranged in series between the output of the supply circuit 2 and the resonator 1.
  • the impedance-resonator pair forming the plasma generation circuit has its resonant frequency shifted with respect to the resonance frequency of the resonator 1 of the insulated coil-candle.
  • the impedance values of the circuits 14 are thus chosen so that the difference in resonance frequency between each plasma generation circuit, each constituted by an impedance-resonator torque, is equal to at least one multiple of the bandwidth of each resonator.
  • the resonance frequency shifting means of a plasma generating circuit relative to another use the connecting cable providing the connection between the output of the supply circuit and each coil-candle as series impedance, the coils -bougies are also identical, namely that their resonator have an identical resonant frequency.
  • it is the length of the cable portion, respectively L1, L2, L3, between the spark-coils, respectively between BB1 and BB2, between BB2 and BB3 and between BB3 and BB4, which acts as an impedance , in particular of inductance, and thus defines the resonator frequency offset between the resonators of the coils-candles.
  • the control method of the single power supply circuit must then take into account the frequency adapted to the channel to be controlled for each ignition.
  • control device 5 of the power supply circuit can have a memory capable of preserving the order of frequency classification corresponding to each of the channels to be controlled.
  • the control device upon receipt of an ignition request, the control device is firstly able to determine the cylinder to be controlled, numbered for example from 1 to 4 in the order of disposition on the motor. Each cylinder number is therefore associated with the resonance frequency, F1, F2, F3 and F4 respectively, specific to the corresponding plasma generating circuit to be controlled.
  • the control device then comprises a module determining the frequency of the control signal to be generated, among these frequencies F1, F2, F3 and F4, as a function of the number of the cylinder to be switched on and the order of classification of the frequencies previously memorized.
  • control device applies the control signal to said frequency on an output interface intended to control the switch M.
  • the selective power transfer to the plasma generating circuit to be controlled for ignition is then naturally managed by the control frequency used for this ignition.
  • the determination of the resonant frequencies to be obtained at the output of the single feed circuit can be controlled by tabulation or servo-control methods as described in the French patent applications filed in the name of the Applicant. FR 05-127669 and FR 05-12770 .
  • control device may be provided with an interface for receiving engine operating parameter measurement signals (engine oil temperature, engine torque, engine speed, ignition angle, air temperature). inlet, pressure in the combustion chamber, etc.) and / or power supply operating parameter measurement signals, as well as a particular memory module storing relationships between measurement signals and the frequency of a control signal to be generated.
  • engine operating parameter measurement signals engine oil temperature, engine torque, engine speed, ignition angle, air temperature
  • power supply operating parameter measurement signals as well as a particular memory module storing relationships between measurement signals and the frequency of a control signal to be generated.
  • the controller determines the frequency of a control signal to be generated based on measurement signals received on the receiving interface and relationships stored in the memory module.
