ABSTRACT:
An electronic spark timing advancing apparatus for an internal combustion engine having an ignition device is disclosed, wherein a crank angle at which an internal pressure of a cylinder of the engine assumes a peak value is detected and a desired crank angle at which the internal pressure of the cylinder is to assume a peak value under a given condition is calculated in accordance with that condition, and a spark timing of the ignition device is controlled in response to a deviation therebetween to minimize the deviation.
