Abstract: An aircraft piston engine magneto having a magnetic rotor and an ignition circuit with a reconfigurable charging coil inductively coupled to magnetic rotor. The charging coil includes multiple coils inductively powered by the magnetic rotor and electronically reconfigurable from a higher turn, lower amperage power coil for use when running at low speeds into a lower turn, higher amperage coil at higher speeds. The charging coil is configured into the higher turn coil by electronically connecting the multiple coils in series, and into the lower turn power coil by electronically connecting the coils in parallel. The ignition circuit is a fully electronic ignition circuit that generates and distributes ignition pulses to the piston engine spark plugs using only non-mechanically actuated electrical components within the magneto.

Abstract: In an engine ignition method according to the present invention, an ignition coil and an exciter coil are provided in a magneto generator driven by an engine. After charging an ignition capacitor using an output voltage of the exciter coil, the ignition capacitor is discharged through a primary coil of the ignition coil at an ignition timing of the engine, whereby a high voltage induced in a secondary coil of the ignition coil is applied to an ignition plug and a first spark discharge is generated in the ignition plug, and a voltage induced in the secondary coil of the ignition coil accompanied with rotation of the magneto rotor is applied to the ignition plug in a state that insulation across discharge gaps of the ignition plug is broken down due to the first spark discharge, whereby a second spark discharge is produced in the ignition plug.

Abstract: In at least some implementations, a method of operating an ignition system for a combustion engine includes charging an energy storage device during at least a portion of the time when the engine is operating, permitting the level of energy stored on the charge storage device to decrease over time after the engine ceases to operate, determining the energy level on the energy storage device when the engine is restarted after having ceased operating, and setting at least one engine operational parameter as a function of the determined energy level. In at least some implementations, the at least one engine operational parameter may include one or more of: richness of a fuel and air mixture to be delivered to the engine, ignition timing, desired engine idle speed.
