ABSTRACT:
A control system for an internal combustion engine, which is capable of properly performing air-fuel ratio control and ignition timing control according to an actual amount of intake air, even when reliability of the results of detection of the operating condition of a variable intake mechanism is low. The control system for controlling air-fuel ratio and ignition timing includes an ECU. The ECU calculates a target air-fuel ratio, calculates an air-fuel ratio correction coefficient, calculates a statistically processed value of an air-fuel ratio index value, calculates a corrected valve lift and a corrected cam phase, and determines a fuel injection amount according to the corrected valve lift, the corrected cam phase, and the air-fuel ratio correction coefficient.
