ABSTRACT:
In an electronic ignition control apparatus for an engine, an actual optimum spark advance angle for activation of a spark plug is determined as a value defined by a linear equation representing a relationship between an optimum spark advance angle and an amount of air sucked into the engine in consideration with an actual rotation speed by using a stored optimum spark advance angle defined by a reference linear equation representing a relationship between the stored optimum spark advance angle and an amount of the sucked air in consideration with a predetermined rotation speed.
