Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the unstableness of an engine due to excess spark advance in an excess fuel condition, in spark-advance-correcting ignition timing at the time of low-temperature engine. SOLUTION: An advance correcting value TADV is set so as to advance with low water temperature in accordance with water temperature Tw usually (S4). In contrast with this, an advance correcting value TADV is fixed to an advance correcting value RADV 1 at the time of water temperature Tw = a given value Tw 1 when water temperature Tw is a given value Tw 1 or less, and an equivalent ratio is in a rich condition wherein an equivalent ratio is a given value 1 or more (S3, S4). A spark advance correcting value TADV is added to basic ignition timing MADV to calculate ignition timing ADV (S6).
