PURPOSE:To prevent the damage of an engine while heightening engine output by providing a knocking control means for delaying the ignition timing by the value corresponding to a knocking level and returning it gradually to the origin after suppressing the generation of knocking. CONSTITUTION:There are provided a knocking detecting means M10 for detecting a knocking level when knocking is generated to an engine M1, and a knocking control means M11 for delaying the ignition timing by the value corresponding to the knocking level and returning it gradually to the origin after suppressing the generation of knocking. With this constitution, an ignition angle is returned by the specified value upon the generation of knocking, so that knocking is stopped. Afterwards, the ignition angle is gradually advanced to increase engine output. In case knocking is generated again at this time, the same process is repeated. |
