An ignition system for an internal combustion engine having a magnetically conducting core with at least three legs and supporting a charging winding and a triggering winding. A flywheel, having at least one magnetic field generating member, cooperates with a magnetically conducting core to cause, when passing, voltages to be induced in the windings. An electronic switch is adapted to trigger, in response to a trigger pulse generated by the triggering winding, the discharge of a first capacitor which has been charged by voltage generated in the charging winding, via the primary of an ignition coil, a secondary of which comprises a spark plug. The triggering winding is wound about two of the legs on the magnetically conducting core whereas a third leg supports the charging winding.
Ignition system for an internal combustion engine, comprising a magnetically conducting core (10) having three legs (11,12,13) and supporting a charging winding (21) and a triggering winding (22), a flywheel (14) having at least one magnetic field generating member (15) and adapted to cooperate with the magnetically conducting core (10) to cause, when passing, voltages to be induced in the windings (21,22), and an electronic switch means (27) adapted to trigger, in response to a trigger pulse generated by the triggering winding (22), the discharge of a first capacitor (26), which has been charged by a voltage generated in the charging winding (21), via the primary (18) of an ignition coil (17) the secondary (19) of which comprises a spark plug (20), wherein the triggering winding (22) is wound about a first two (11,12) of the three legs, as seen in a normal direction of rotation of the flywheel, on the magnetically conducting core (10) whereas a third of said three legs (13) supports the charging winding (21).
