Definitions

  • the present invention relates to a method for controlling ignition parameters of a spark plug for an internal combustion engine and an ignition device using such a method.
  • These ignition coils generally consist of a primary winding, called primary, connected to a DC source, such as the battery of a motor vehicle, and a secondary winding, called secondary, connected to a candle and which, under the effect of the voltage applied to the primary, generates a high voltage that will be applied to the spark plug to form the electrodes thereof an electric arc or spark that ignites the air / fuel mixture.
  • This ignition the triggering time of which will be determined by a computer, referred to as the engine computer, which a motor usually comprises, is therefore dependent on the quality of the arc, that is to say mainly on its duration and electrical parameters such as the Current intensity, voltage, ...
  • the primary of this coil is further connected in series with a field effect transistor which acts as a switch whose opening and closing phases are controlled by a control.
  • a field effect transistor which acts as a switch whose opening and closing phases are controlled by a control.
  • the present invention proposes to overcome the disadvantages mentioned above by having an ignition device replacing the ignition coil and to easily control all the parameters related to the electric arc of the candle.
  • a method for controlling ignition parameters of a spark plug for an internal combustion engine whose ignition is ordered by an engine control computer said candle receiving a high voltage and a current emanating from an ignition emulator, a method in which the target values are determined in current and / or in voltage to obtain the desired electric arc at the electrodes of the candle, these target values are stored in a parameterization unit, measured , at regular intervals, after the ignition command given by the computer, at least one voltage and / or current parameter emanating from the emulator, these parameters are compared with the target values and, in case of drift between the parameters measured values and the target values, these parameters are adjusted to reach the target values, characterized in that a chopper (14) is supplied with voltage by a voltage converter (10) and in that at least one mo interruption yen (K1, K2, K3) of said voltage converter (10) and / or said chopper contained in the emulator (E) for controlling the voltage (U_HT) applied to the spark plug.
  • a chopper (14) is supplied with voltage by a voltage converter (10)
  • At least one chopper interruption means for controlling the voltage rise applied to the spark plug.
  • the invention also relates, for the implementation of the method, to an ignition emulation device for an internal combustion engine according to claim 5.
  • the control box may include inputs for voltage and / or current signals emanating from the emulator.
  • control box may comprise at least one input for at least one target voltage and / or current value to be applied to the spark plug.
  • the housing may include at least one output for control signals to interrupt means included in the emulator.
  • an ignition emulator E for an internal combustion engine especially a motor vehicle, comprising a voltage converter 10 for converting the voltage from a battery 12 to a voltage of 600V, here preferably up to at 400V, and a chopper 14 for generating a high voltage on a candle 16, high voltage which will generate an electric arc or spark at the electrodes of this candle thus making it possible to ignite an air / fuel mixture present in a combustion chamber.
  • a voltage converter 10 for converting the voltage from a battery 12 to a voltage of 600V, here preferably up to at 400V
  • a chopper 14 for generating a high voltage on a candle 16, high voltage which will generate an electric arc or spark at the electrodes of this candle thus making it possible to ignite an air / fuel mixture present in a combustion chamber.
  • the converter 10 comprises a switch K3 making it possible to vary the voltage at its output up to the desired voltage to be applied to the chopper 14.
  • the chopper 14 whose input is connected to the output of the converter 10 comprises a transformer 18 equivalent to an ignition coil with a primary 20 and a secondary 22.
  • the primary 20 comprises two switches, a high switch K1 for controlling the rise of current in this primary and a high switch K2 for the descent of this current in the same primary.
  • the secondary 22 is connected, in a conventional manner, to the spark plug 16 by an electrical conductor 24.
  • This emulator is connected to a control box 30 (see figure 2 ) which receives measurement input signals from the emulator E, target value signals from a parameterization unit 32 via a channel 34 and which outputs signals to control the switches K1 and / or K2 and / or K3 and / or K4 of emulator E.
  • the parameterization unit 32 contains all the theoretical target values that make it possible to obtain the desired electric arc at the candle for a determined period of time. These values are in particular the voltage (Ucible_HT) and the current intensity (Icible_HT) at the output of the chopper 14, the voltage (Ucible_Boost) and the intensity of the current (Icible_Boost) at the output of the converter 10. These target values thus make it possible to determine the maximum voltage at the secondary (Us max), the moment (Tmax US) at which this maximum voltage must be reached and the voltage (Uarc) to maintain the electric arc at the electrodes of the candle for a determined time (Ts).
  • the unit 32 can thus contain values making it possible to simulate all forms of coils with capacitances ranging up to a secondary voltage of 50kV in a time ranging from 10 ⁇ s to 500 ⁇ s, an arc duration at the candle electrodes of 10 ⁇ s (microseconds) to 10 ms (milliseconds) and a current intensity applied to the secondary up to at 1 A.
  • the chosen theoretical values are communicated by channel 34 to the box 30 which, in addition, receives the input signals measuring the actual battery voltages (U_Batt), the output of the converter (U_Boost) and the output of the chopper (U_HT) as well as as input signals corresponding to the measurement of the actual currents at the switch K3 of the converter (I_Boost), at the low switch K2 of the chopper (I_K2) and at the output of the chopper (I_HT).
  • U_Batt the actual battery voltages
  • U_Boost the output of the converter
  • U_HT the output of the chopper
  • the parameter unit 32 may also contain other values such as the number of arcs in case of multi-spark ignition and the time between two arcs.
  • the ignition device according to the invention makes it possible to obtain, in the upper part, the voltage curve as a function of the time measured at the secondary and, at the bottom, the curve of the intensity of the current as a function of the time recorded at the secondary.
  • the ignition device has to adjust all the parameters necessary for the voltage curve to correspond to that of the theoretical curve of the figure 3 so that the intensity curve has a general shape approximating that of the theoretical curve.
  • the voltage and / or current measurements are made every microsecond as soon as the ignition switch of the engine control unit is switched off, that is to say after the ignition was given by this calculator and even before the electric arc is created at the electrodes of the candle.
  • the latter will control the switch K3 to increase or decrease the voltage at the input of the chopper 14 which will cause an increase or decrease in the voltage of the primary 20 and by therefore an increase or decrease in high voltage at secondary 22.
  • the housing can also, thanks to the commands on the switches K1 and K2, control the rise of the current in the primary 20 by the switch K1 and / or the descent of this current through the switch K2, which will have for influence to control the rise and fall of the high voltage that will be applied to the candle 16.
  • switches K1, K2 or K3 or K4 can be ordered separately or together or in combination.
  • the emulator E comprises an ionization module 26 which makes it possible to know whether there has been a combustion in the chamber considered of the engine and thus to determine that the ignition parameters are correctly established for achieve this combustion.
  • the emulator E comprises a voltage source 28, variable through a switch K4, and which will allow to inject the calculator that usually comprises a motor, a current similar to that of a ignition coil to prevent any fault in said computer, this current being measured by the housing 30 by the U_Cde channel.
  • the invention described above can also be applied to an internal combustion engine simulation bench.
  • the parameterization unit will be replaced by any means such as a PC computer type calculator, which will allow to directly parameterize a multitude of ignition device with various waveforms that can be generated by the secondary .
