制御装置。 A throttle sensor that detects the throttle opening, a rotation sensor that detects the engine speed, a control unit that determines the injection time based on the output of these, and a fuel injection device that controls the injection amount by this control unit. In addition, the control unit includes basic injection time determining means for determining a basic injection time based on the outputs of the respective sensors, and determining a correction value based on the output of a temperature sensor that detects a thermal state of the engine. A correction value determining means, an actual injection time determining means for determining an actual injection time based on the correction value and the basic injection time, and an injection control means for issuing a command to the fuel injection device based on the actual injection time. A fuel control device for a two-stroke engine, characterized by comprising:
