Abstract:
A capacitor discharge ignition system for an internal combustion engine comprising:a ferromagnetic core;a primary charge coil on the core;a permanent magnet rotatable by an engine to generate pulses in the primary charge coil;an ignition coil having a primary winding and a secondary winding, the secondary winding being constructed to be connected across a spark plug;a capacitor charged in part by the pulses in the primary charge coil;a circuit for discharge of the capacitor through the primary winding;an electronic control for controlling discharge of the capacitor;a secondary charge coil on the core;energy storage means for providing energy to the secondary charge coil; andan electronic switch for selectively providing current from the energy storage means to the secondary charge coil to charge the capacitor to increase the charge stored on the capacitor to facilitate starting the engine at relatively low engine rotary speeds.
