ABSTRACT:
An internal combustion engine employs an alternator driven capacitor dishcarge ignition system wherein a stator coil assembly provides power pulses to charge the capacitors and an adjustably positionable coil assembly provides electrical pulses whose frequency and magnitude (bias voltage) are related to engine speed and effect ignition timing i.e., capacitor discharge. An electronic solid state ignition timing and detonation controller is connected to the capacitor discharge ignition system and operates in response to the pulses from the high speed winding of the aforesaid stator coil assembly to supply a bias signal which reduces the aforesaid bias voltage from the said other coil assembly at higher engine speeds thereby providing additional spark advance, depending upon engine speed and detonation severity. The electronic controller improves engine efficiency at cruising speeds and reduces detonation at high speeds.
