ABSTRACT:
A method for reducing knocking in an internal combustion engine providing an improved response to changes of operating conditions of the engine and which is capable of producing precise knocking control under all combinations of operating conditions. The knocking level, load condition and rotational speed of the engine are detected. At addresses of a memory defined by the load and speed of the engine, values are stored which are calculated in accordance with the detected knocking levels, and ones of these values are read out in accordance with addresses corresponding to a present combination of a load condition and engine speed. At least one control parameter, such as the ignition timing, is corrected on the basis of the values read out from the memory and the detected knocking level. The values stored in the memory are changed at predetermined periods bidirectionally.
