エンジン。 An alcohol/gasoline mixed fuel engine is equipped with an alcohol concentration detection device that detects the alcohol concentration in the fuel supplied to the engine and sends an alcohol concentration detection signal to the control section of the engine. An alcohol concentration sensor is installed in the fuel supply passage leading to the intake pipe, and an alcohol concentration sensor is disposed in the detection device, and an alcohol concentration sensor is installed upstream of the sensor and heats the fuel according to its temperature before the sensor detects the alcohol concentration. 1. An alcohol/gasoline mixed fuel engine equipped with an alcohol concentration detection device, characterized in that a fuel heating means is controlled to operate to prevent phase separation.
