A double coil ignition system which is operated from separate opto-electronic triggers, the secondary windings of the two coils being connected to supply energy to the same spark plug or distributor system, the first coil providing a high voltage discharge in order to ionize the gap across the spark plug and the second coil providing a low voltage high current discharge at a given crank-shaft position after the first coil has ionized the gap, the second coil thus delivering a high current across the gap to ensure the complete combustion of lean fuel mixtures. |
