Abstract: An engine control device 21 controls the fuel injection amount on the basis of an opening degree of a throttle valve 10 when an opening-degree signal value is equal to or larger than a predetermined value, and controls the fuel injection amount on the basis of an intake pressure when the opening-degree signal value is smaller than the predetermined value. The engine control device 21 sets the predetermined value to a larger value as the opening degree of a starting solenoid 7 is larger, the opening degree being controlled by an auxiliary-intake-valve control unit 23.
