ABSTRACT:
High octane fuel and low octane fuel are supplied into the combustion chamber of an engine from high-octane fuel tank and low octane fuel tank via a high octane fuel injector and a low octane fuel injector. During a knocking control, if the quantity of high and low octane fuels in the respective tanks has been unbalanced, the supply ratio between high octane fuel and low octane fuel is changed 1 to control a knocking occurring in the engine without changing the ignition timing.
