ABSTRACT:
A spark ignition timing control system includes pressure sensors monitoring internal pressure in respectively associated combustion chambers. The outputs of the pressure sensors are processed for detecting crank shaft angular position at which the internal pressures in respective combustion chambers become maximum. Angular difference of the crank angular maximum pressure positions at which the internal pressures of the combustion chambers become maximum, with target angular positions for deriving are derived. The present invention features that correction value for correcting a basic spark advance for each engine cylinder is composed of first and second components. The first component is derived on the basis of the angular difference value derived with respect to the maximum pressure position of the corresponding engine cylinder. On the other hand, the second component is derived on the basis of the angular difference values derived with respect to the maximum pressure positions of other cylinders.
