ABSTRACT:
An ignition timing control system for an internal combustion engine comprises first signal generating means for generating a first signal at a crank angle position of the engine corresponding to each one of a plurality of cylinder groups; second signal generating means for generating a second signal at a crank angle position corresponding to a top-dead-center position of each cylinder, and distributing means for distributing ignition command signals to ignition devices provided for respective cylinder groups, in response to the first and second signals. Further, cylinder-discriminating means is provided for generating a third signal at a crank angle position corresponding to a particular one of the cylinders in response to the first and second signals.
