Abstract:
1. An idling state stabilizing device for an engine, comprising: a power generation control device disposed between a generator comprising a flywheel magneto with a magnet type three-phase power generating body coupled to the engine and one or more electrical components of a vehicle configured to provide an electric load to the generator, the power generation control device comprising the power generation control device configured to set a predetermined threshold engine speed value at or below which the engine is determined to be in an idling state as an idling state rotational speed value, and configured to set an idling state output current value of the generator as a normal output current value when the engine is in the idling state, the power generation control device further configured to determine an engine speed fluctuation amount of the engine within a predetermined time interval while the engine is in the idling state; wherein the power generation control device determines that the engine is in the idling state when the engine speed detected by the engine speed detector is equal to or less than the idling state rotational speed, the power generation control device configured to control a current amount output by the generator to be a revised output current value lower than the normal output current value when the determined engine speed fluctuation amount is equal to or greater than a predetermined engine speed fluctuation amount.
