The alcohol concentration detection value estimated or detected by the alcohol concentration sensor is corrected in accordance with intensity, frequency and the like of knocking to set the alcohol concentration detection value after the correction as the alcohol concentration for ignition timing control. Thereby, occurrence of the knocking can be prevented by changing ignition timing in accordance with the knocking state. In regard to the fuel injection control, the alcohol concentration detection value before the correction is used as the alcohol concentration for fuel injection control as it is without using the alcohol concentration detection value corrected in accordance with the knocking state. This prevents a fluctuation of the fuel injection quantity due to correcting the alcohol concentration detection value in accordance with the knocking state, leading to prevention of a torque fluctuation or combustion deterioration.
