ABSTRACT:
In an engine using fuel mixture of gasoline and methanol, the present control system compensates a detection value of a blend ratio sensor with a detection value of a knock sensor, or causes trouble detecting means to detect a failure of the blend ratio sensor and memories the blend ratio immediately before the failure as an assumed blend ratio and compensates the stored value with the detection value of the knock sensor, whereby the engine control is executed based on the control blend ratio and the ignition timing acquired through the compensation.
