ABSTRACT:
In response to the occurrence of knocking in an internal combustion engine, the basic ignition timing is corrected in a direction to retard it through the charging and discharging of an integrator circuit. The integrated current output of the integrator circuit is varied in accordance with a voltage corresponding to the speed of the engine so as to limit the maximum amount of ignition timing retard at low speeds or high speeds of the engine.
