<p>The invention concerns a method for controlling ignition parameters of a spark plug (16) for an internal combustion engine whereof the ignition is controlled by an engine control calculator, said spark plug receiving a high voltage (U_HT) and a current (I_HT) derived from an ignition emulator (E). Said method consists in: establishing target current and/or voltage values (Ucible_HT, Ucible_Boost, Icible_HT, Icible_Boost) for obtaining the desired electric arc at the spark plug electrodes, storing said target values in a parametering unit (32), measuring, at regular intervals, after ignition command by the calculator, at least one voltage parameter (U_HT, U_Boost, U-Batt) and/or a current parameter (I_HT, I_Boost) coming from the emulator, comparing said parameters with the target values, and in case of variation between the measured parameters and the target values, adjusting said parameters to achieve the target values for controlling the ignition parameters of a spark plug for an internal combustion engine, said spark plug receiving a voltage (U_HT) and a current (I_HT) derived from the ignition emulator (E). The invention consists in acting on at least one interruption means (K1, K2, K3) to control the voltage applied to the spark plug.</p> |
