ABSTRACT:
A method for controlling the ignition timing of internal combustion engines in which the magnitude of knocking is detected for each of at least two different magnitude levels. A knocking signal representing the detected magnitude level of the knocking and produced in each combustion cycle of the engine is sampled for a predetermined number of combustion cycles of the engine, and an ignition timing correction signal is produced to effect either to retard or advance depending on whether the sampled number of the knocking signals is above or below a predetermined reference number.
