Abstract

PURPOSE:To make it possible to prevent a knocking by advancing the ignition timing after a specific time passes, when the object air-fuel ratio is transferred from the rich side to the lean side. CONSTITUTION:The CPU 10 sets the ignition timing responding to the preset object air-fuel ratio and signals from an engine rotation sensor 11 and an absolute pressure sensor 15, and feeds the control signal to an ignition control circuit 23. In this case, when the object air-fuel ratio is transferred from the rich side to the lean side, the ignition kept at the value of the air-fuel ratio rich, that is, at the lag angle side, regardless of the actual air-fuel ratio, until a TDC signal pulse is generated in specific rounds. And after the TDC signal pulse is generated in the specific rounds, the ignition timing is controlled at the value for the air-fuel ratio pole lean or for the air-fuel ratio rich according to whether the actual air-fuel ratio is in the pole lean area or not. Since the actual air-fuel ratio is controlled to the advanced angle side after controlled to the object air-fuel ratio which is the value of the pole lean side accordingly, the generation of knocking can be prevented securely, and the operational property can be improved.
