ABSTRACT:
An ignition timing control apparatus for an engine, which corrects the ignition timing in accordance with the presence/absence of exhaust gas to be recirculated into a combustion chamber by an exhaust gas recirculation (EGR) apparatus is described. An electronic control unit (ECU) controls the EGR apparatus in accordance with the running condition of the engine to control the EGR amount. The ECU computes a base ignition timing in accordance with the running condition of the engine and corrects the computed value toward advancement by a predetermined value in accordance with the EGR amount. Further, the ECU corrects the compensated value of the ignition timing by a predetermined value toward retard to the timing close to the limit beyond which knocking starts. Furthermore, the ECU limits the retard angle value within the range of the maximum value which is computed in accordance with the engine's running condition, and changes the retard angle value or the maximum value in accordance with the EGR amount. Based on the value of the final target ignition timing computed in the above manner, the ECU controls an igniter to control the actual ignition timing to the proper timing.
