Abstract

L'invention concerne un système d'allumage. Selon l'invention il comprend deux bobines 1, 2 qui sont commandées par des délclencheurs opto-électroniques séparés X1, X2; des enroulements secondaires S1, S2 des deux bobines sont connectés pour fournir de l'énergie au même système distributeur Z ou aux bougies 3, une bobine ionisant toujours l'éclateur pour permettre aux deux bobines de fournir leur énergie simultanément. L'invention s'applique notamment à l'industrie automobile.The invention relates to an ignition system. According to the invention it comprises two coils 1, 2 which are controlled by separate opto-electronic triggers X1, X2; secondary windings S1, S2 of the two coils are connected to supply energy to the same distributor system Z or to the spark plugs 3, one coil still ionizing the spark gap to allow the two coils to supply their energy simultaneously. The invention applies in particular to the automotive industry.
