ABSTRACT:
An ignition timing control apparatus for an internal combustion engine comprises a signal rotor rotating in synchronism with the revolution of the engine, a plurality of trigger poles attached on the outer circumference of the signal rotor at positions corresponding to an ignition timing for each of the cyclinders, a signal coil for generating an angle signal in correspondence to the position of the trigger poles and an ignition timing operating device which measures the periods in the angle signal and compares the periods by multiplying a given coefficient alternately to thereby discriminate the cylinders and operate ignition timing for the cylinders.
