ABSTRACT:
The heat generating ratio for every crank angle is calculated as a combustion ratio for the total amount of heat generated by the engine, and the ignition timing is so corrected that the crank angle corresponding to from 10% to 90% of the combustion ratio becomes minimal or is so corrected that the combustion ratio at a predetermined crank angle becomes equal to or larger than a predetermined value. This makes it possible to so control the ignition timing that the engine produces a maximum torque.
