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.
