Abstract
An ignition timing control system in a spark ignition type internal combustion engine which has multiple cylinders, wherein ignition pulses generated in accordance with the operating condition of the engine are delayed in response to knockings detected to control the ignition timings to the optimum advance conditions free from knockings, has such characteristic features that respective cylinders of the engine are controlled in ignition timing independently of one another, a detected knocking signal is divided for the respective cylinders and only the ignition pulses corresponding to the cylinders of knocking is delayed so that the optimum advance conditions for the respective cylinders can be obtained.
