Abstract:
A contactless ignition system for an internal combustion engine, comprising, a rotor having magnetic poles arranged either side of a magnet, a core, arranged opposite the rotor, wound with a generating coil and a trigger coil, an ignition charge discharge condenser for charging an induced voltage of the generating coil, a first switching element, triggered to be conductive when an induced voltage of the trigger coil has reached an initial trigger level, for supplying a voltage charged in the ignition charge discharge condenser to an ignition coil, a trigger control condenser for charging induced voltages of the charging coil and the trigger coil, and a second switching element for inhibiting a trigger of the first switching element caused by induced voltage of the trigger coil for a specified time following charge of the trigger control condenser.
