Abstract

PURPOSE:To initialize negative pressure in stopping an engine for preventing over-rotation in the next start when negative pressure is introduced from a vacuum tank into an actuator to feedback control rotational frequency on the basis of the deviation of rotational frequency from a set value. CONSTITUTION:To an engine speed controller 20 are input an ignition signal of an ignition coil 21, setting signal of a rotational frequent setter 22 and signals of a set switch 23 and cancel switch 24 to adjust negative pressure to an actuator 11 through a control valve 6, vent valve 8 and gain control valve 13 to adjust negative pressure to an actuator 11, control the opening of a throttle valve 18 and feedback control the rotational frequency. When the stoppage of an engine is judged on the basis of an ignition signal from the ignition coil 21, the control valve 6, vent valve 8 and gain control valve 13 are controlled to initialize a vacuum tank 3 and the actuator 11.
