PROBLEM TO BE SOLVED: To provide a method of determining an optimum ignition timing from viewpoints of minimum fuel consumption and exhaust gas emission.SOLUTION: An ignition timing ZWfinal is determined on the basis of a plurality of input values rl, n, V1, V2, V3 by using a model based on at least one data. The model 11 based on at least one data, for example, includes an ignition angle model 11 based on the data, and/or a correction model based on one or a plurality of other datum to correct an ignition timing ZW determined by the ignition angle model. |
