ABSTRACT:
An ignition timing control system for an internal combustion engine includes an ECU which calculates a knocking correction value in response to an output from a knocking sensor, and an advance limit value in response to engine operating conditions. The ECU operates to limit correction of the ignition timing of the engine in an advancing direction, beyond the advance limit value when the knocking correction value exceeds the advance limit value. The ECU cancels the advance correction limitation when at least one of conditions of high coolant temperature, high intake air temperature, low coolant temperature, and low rotational speed is satisfied.
