Abstract
In determining an optimum target fuel ignition timing in accordance with the engine operating conditions, including at least an engine load and an engine speed, the target ignition timing is determined on the basis of a corrected engine load and a corrected engine speed. The corrected engine load and corrected engine speed are obtained by making corrections, according to the engine operating conditions, to a detected engine load and a detected engine speed, respectively. In this way, the optimum target fuel ignition timing according to the engine operating conditions can be obtained without directly detecting a fuel injection quantity.
