Abstract
A method of detecting the breakdown voltage between the electrodes of a spark plug connected to an ignition coil for a cylinder ignition system, in an internal combustion engine, includes a detection of an opening of the switch on the primary winding and a detection of a voltage on that primary winding, with the generation of a first signal representative of the voltage trend following the opening of the switch. The first signal is then integrated and, following an identification of a breakdown at the ends of the spark plug, a breakdown voltage value is determined as a function of the value of the integrated signal at the time of the breakdown.
