てなる燃料のアルコール濃度測定装置。 Concentration detection means for detecting alcohol concentration from the resistance value or voltage value of fuel mixed with alcohol, and comparison for comparing the detected resistance value or detected voltage value from the concentration detection means with a detectable limit resistance value or limit voltage value. and when the comparison means determines that the detected resistance value or the detected voltage value is below the limit resistance value or the limit voltage value, outputs the alcohol concentration corresponding to the detected resistance value or the detected voltage value, and outputs the alcohol concentration corresponding to the detected resistance value or the detected voltage value. A fuel alcohol concentration measuring device comprising an output means that sometimes outputs a predetermined alcohol concentration.
