OVER REVOLUTION PREVENTION DEVICE DURING IDLING AND CONTROL METHOD THEREOF, TO PREVENT EXCESSIVE RISE OF ENGINE RPM DURING IDLING

摘要

PURPOSE: An over revolution prevention device during idling and a control method thereof are provided to prevent breakage of an engine by operating an actuator by electronic control and fixing the operation of a throttle valve if excessive rise of engine RPM(Revolution Per Minute) during idling occurs. CONSTITUTION: An over revolution prevention device during idling comprises on/of switches(6,8) mounted to an accelerator pedal(1) and a clutch pedal(7) to inform of the operation state of each pedal; an electronic control unit(10) checking engine RPM together with operation signals from the on/off switches; and an actuator(9) controlling the operation of a throttle valve(3) by the signal of the electronic control unit.
