Abstract
A knock suppression system for an internal combustion engine in which the occurrence of knocks is suppressed by quickly providing a corresponding control signal previously stored in a memory and determined on the basis of operating conditions of the engine so that knocks can be effectively suppressed. As the operating conditions vary due to change in ignition timing, A/F ratio, combustion chamber temperature, inlet air temperature, humidity, or the like, the control signal is corrected and updated to compensate for the change in knock level. Also, even at the transient state of the engine where the factors introducing knocks largely vary, a correction control signal corresponding to the variations during the transient operation can be carried out, thereby effectively and quickly suppressing engine knocks.
