回転数制御装置。 An ignition coil that ignites the engine, an ignition circuit that controls the current flowing through the ignition coil, and an ignition circuit that controls the ignition spark generated in the ignition coil when the engine speed reaches a predetermined value. A rotation speed control circuit is provided to control the rotation speed, and the predetermined value is set to a first predetermined value and a second predetermined value lower than the first predetermined value, and the first predetermined value is set by inputting an external signal.
switching from a predetermined value to a second predetermined value,
During the control period using the second predetermined value, switching from the second predetermined value to the first predetermined value is prohibited, and during the non-control period using the second predetermined value, the second predetermined value is switched on the condition that there is no external signal input. 1. A rotation speed control device for an internal combustion engine, characterized in that it is possible to switch from a predetermined value to a first predetermined value.
