Abstract
The overspeed ignition system includes trigger means operative in timed relation to the speed of an internal combustion engine. A controlled switching means operates under the control of the trigger means to pass pulses of energy to a spark ignition unit. An overspeed cutout assembly is provided between the controlled switching means and the spark ignition unit to sense the time interval between the pulses of energy passed by the controlled switching means. When this time interval is less than an internal timed lockout interval determined by the overspeed cutout assembly, the cutout assembly blocks the pulses of energy to the spark ignition unit. The trigger means is formed by a trigger pulse generating assembly having a rotor of circular cross section symmetrically mounted for rotation relative to at least one trigger coil. The rotor is differentially magnetized to prevent pulses of energy from passing to the spark ignition unit when the engine rotates in a reverse direction. This rotor is part of a novel flux conducting flywheel unit which forms part of the flux path for the rotor to enhance the pulse generating capability of the trigger pulse generating assembly.
