Method for controlling the ignition circuit of an internal combustion engine, and device for detecting and/or measuring the ignition current in such an ignition circuit for implementing this method

摘要

In order to control the electrical ignition circuit of an internal combustion engine, the electrical current in the high-tension part of the said circuit is detected and/or measured, then the signal representing the said current is processed in order to deduce therefrom the information item or items necessary for controlling the state of operation of the circuit; means 6 for emitting electromagnetic radiation are provided, including in the high-tension part of the ignition circuit, and arranged so that the radiation power emitted is a function of the presence, and/or reception means 8 for the said radiation included in the low-tension circuit for processing the output signal from the reception means.
