Abstract

An ignition timing control system for an internal combustion engine comprises first circuitry for producing a function of the intensity of combustion knock in each cylinder in a sequence, second circuitry for storing the function of each cylinder respectively in a memory circuit each of which corresponds to a specific cylinder, and third circuitry for determining the ignition timing of each cylinder by modifying the basic ignition timing determined by an advance mechanism, in accordance with the respectively stored functions.
