。 A throttle valve that opens and closes in conjunction with accelerator operation and a governor valve that opens and closes according to engine operating conditions are arranged in the intake passage of the engine, with the throttle valve located on the upstream side of the intake air. In the engine, the opening degrees of the throttle valve and the governor valve are such that the minimum opening degree of the throttle valve is larger than the twist of the governor valve, and the maximum opening degree of the throttle valve is smaller than that of the governor valve. Further, the governor valve is driven by a motor, and a throttle valve opening detection means for detecting the minimum opening and maximum opening of the throttle valve and the engine rotation speed are set relatively to each other so that 1. An engine control device comprising: an engine rotation speed detection means for detecting engine rotation speed, and the motor is controlled according to the engine rotation speed and a throttle valve opening state.
