<p>PURPOSE:To obtain a number-of-revolution change controller in which a decrease in the number of revolutions of an engine can be suppressed even if an electric load increases during idling, and low speed operating, waste of a battery, uncomfortable vibration, and increase of cost are suppressed. CONSTITUTION:The number-of-revolutions change controller comprises an electric load in which a rectified output from a generator 10 is supplied as required, a battery 12 to be changed by the rectified output from the generator, a regulator 10R for so controlling a field current IF of the generator that a battery voltage VB becomes a set value VA, a target voltage calculator 21 for calculating a target voltage VR of the battery based on an operating state of an engine, and field current limiting means 15A for limiting a field current of the generator in response to a voltage deviation DELTAV of the battery voltage from the target voltage. A generating amount is limited separately from control of the number of revolutions of idling due to feedback to a suction system having a bypass air passage.</p> |
