PURPOSE:To always suppress generation of knocking by delaying an ignition timing amount by a predetermined delay timing amount, when the generation of knocking is detected, thereafter increasing the ignition timing amount in every predetermined advance timing amount by a predetermined period while changing these predetermined amounts in accordance with an engine temperature. CONSTITUTION:A processing unit 31, when it detects the generation of knocking by a signal from a knocking detector 38, delays an ignition timing amount thetaby a preset delay angle theta1 to be increased thereafter in a predetermined period W by every preset advance timing angle theta2, performing a control of ignition timing. Here of the control actions such as increasing the delay timing angle THETA1 to a large value, decreasing the advance timing angle theta2 to a small value and increasing the period W to a large value following a temperature rise detected by a temperature detector 24 in an internal combustion engine 13, at least one control action is performed. Thus suppressing the generation of knocking decreasing the fluctuation of torque, the improvement of drivability and fuel consumption can be contrived. |
