摘要： Ignition system for an internal-combustion engine, in particular for use in a chain saw or the like, comprising a magnetically conducting core supporting a charging winding and a triggering winding, a flywheel having at least one magnetic field generating member and adapted to cooperate with the magnetically conducting core to cause, when passing, voltages to be induced in the windings, and an electronic switch means adapted to trigger, in response to a trigger pulse generated by the triggering winding, the discharge of a capacitor, which has been charged by a voltage generated in the charging winding, via the primary of an ignition coil the secondary of which comprises a spark plug. The ignition system comprises an additional winding which is provided and disposed so that during its normal rotational movement the flywheel first passes said additional winding before turning in over the legs of the magnetically conducting core, the voltage induced in the additional winding being used to prevent trigger pulses from reaching the switch means if the direction of rotation of the engine is the opposite to the normal one.

摘要： 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.
