Abstract
A control apparatus for an internal combustion engine operable on fuels of different octane numbers implements automatic control when the engine knocks to correct the ignition timing preset in accordance with the octane number of the fuel in use to the retarded side so that the engine operates under the optimum condition. This automatic control enhances engine output and drivability, prevents engine fracture and saves fuel cost.
