PURPOSE:To save the fuel consumption by reducing the revolustions of the engine when unloaded while the revolutions thereof is turned to the rated one when loaded. CONSTITUTION:When a generator 2 is unloaded, the output of a current transformer 4 becomes zero to close a contact (b) of a relay device 5. This actuates a deceleration relay 6 to excite a solenoid 7 whereby a governor 8 of the engine 1 moves to a low speed position. When loaded, the current transformer 4 outputs current to turn the governor 8 to the rated rotation position. Thus, the fuel consumption can be reduced. |
