ABSTRACT:
Undesired knocking in a spark-ignited internal combustion engine is avoided by selectively retarding ignition for individual combustion chambers the first time knocking occurs to identify the knocking combustion chamber and storing the identified combustion chamber in a memory so that, upon later knocking, shifts in the ignition timing of individual combustion chambers can be made utilizing the known ignition sequence.
