<p>PURPOSE:To make it possible to try saving of fuel and damping noise by controlling an engine speed by means of an actuator on the basis of an inverter load current detection signal and a generator voltage detection signal. CONSTITUTION:Electric power generated by a generator 3 is supplied to an inverter unit 4 to be used as an external power supply by means of a socket 9 and a signal from an electric current sensor 6 installed between the generator 3 and the inverter unit 4 is supplied to a controller unit 7 as a load current detection signal of the inverter unit 4. Also, a voltage detection signal from the generator 3 is supplied to the controller unit 7. The controller unit 7 supplies a control drive signal to an actuator 8 on the basis of each detected signal to control an engine speed. Thus, the position of a thrust shaft 33 is detected by signals from detectors so as to return the engine speed certainly to its idling state in such conditions as providing possibility for generating power sufficiently in the idling state, or as providing inoperative state of a power generation mechanism 1.</p> |
