CONTROL DEVICE FOR ENGINE

In an engine having fuel supply means for supplying fuel containing gasoline to a combustion chamber and ignition means for igniting an air-fuel mixture, if knocking occurs when ignition is performed at a reference ignition timing set on a retarded side of MBT that is an ignition timing at which the engine torque is maximized in a high-load region in which the engine load is larger than a predetermined load, ignition advance control that causes the ignition means to perform ignition at a timing on an advanced side of the reference ignition timing is performed.
