摘要： An ignition timing control apparatus for an internal combustion engine having a plurality of cylinders. The apparatus includes a knock sensor for detecting a knocking condition in the engine, sensors for detecting other operating conditions of the engine, a microprocessor unit for receiving signals from the sensors to determine a basic ignition timing of the engine and generate an ignition timing control signal, and a power transistor circuit responsive to the ignition timing control signal from the microprocessor unit to switch on and off the primary current in an ignition coil and generate a high-voltage ignition signal. The microprocessor unit has a control function of retarding the basic ignition timing a predetermined amount in response to a knock detected during an ignition operation at the basic ignition timing and another control function of gradually restoring the retarded ignition timing to the basic ignition timing in response to a knock detected during an ignition operation at the retarded ignition timing from the basic ignition timing. The apparatus includes control means responsive to the occurrence of a knock to correct the basic ignition timing for each cylinder of the engine whereby the basic ignition timing of each cylinder is controlled to be retarded in response to the detection of a knock in each cylinder.
