検出装置。 In an internal combustion engine that uses mixed fuel containing alcohol, there is a capacitive alcohol sensor that outputs a voltage corresponding to the alcohol concentration in the mixed fuel, and an output that determines whether the output voltage of the alcohol sensor is above a predetermined value. Voltage determining means; Alcohol concentration setting means for setting the alcohol concentration based on the output voltage when the output voltage is greater than or equal to a predetermined value; and Alcohol concentration fixing means for fixing the alcohol concentration at the predetermined value when the output voltage is less than the predetermined value. An alcohol concentration detection device for an internal combustion engine, comprising: means.
