Electronic ignition control system.

摘要

@ In an electronic ignition control system utilizing a microcomputer, a reference signal indicative of a crank reference position is counted to sense the rotation speed of an internal combustion engine thereby controlling the ignition timing of the engine. In the system, a reference ignition position is computed using the sensed engine rotation speed as a parameter, and this reference ignition position is corrected using a plurality of information indicative of the operating condition of the engine including the information of the engine rotation speed as parameters.
