PROBLEM TO BE SOLVED: To provide an engine knocking control device which can reduce the ignition timing phase lag when the knocking is generated while ensuring the operability, avoid the knocking and minimize the exhaust temperature rise caused by the ignition timing phase lag, degradation of the fuel economy and output. SOLUTION: The knocking control device 300 comprises a knocking judging means 303 to judge the presence/absence of the knock based on the knocking detection signal by a knock sensor 117, an ignition timing control means 304 to control the ignition timing based on the result of judgment, and a variable valve system control means 501 to variably control the valve timing of the engine, and when the presence of the knocking is judged, and the ignition timing is delayed, the opening/closing timing of an intake valve is delayed by the variable valve system control means 501 according to the phase lag.
