Abstract
Disclosed is an engine drive system that uses an open-type regulator as a regulator that rectifies an output and adjusts a voltage of a magneto AC generator driven by an engine. A means is provided that performs a process of increasing an opening degree of an ISC valve for a limited amount of time when a load of the generator is applied, while the engine is idling. Temporarily increasing an output torque of the engine prevents a rotational speed of the engine from dramatically decreasing, or the engine from stalling, during idling.
