Abstract (en)
A system (1) comprising: a first block (7) for producing an inductive discharge between the electrodes of a spark plug (6) of an engine (3); a second block (8) for producing a capacitive discharge between the electrodes of the spark plug (6); an electronic control system (2) to which are supplied signals relative to operating parameters and conditions of the engine (3), and which provides for selecting an inductive, capacitive, or combined inductive and capacitive discharge, and for phasing the two discharges in the case of a combined discharge; a third block (5) enabled by the electronic control system (2), for controlling the first and second blocks (7, 8). <IMAGE>
