Development of Idling Stop System for 125 cm 3 Scooters with Fuel Injection 2010-32-0121

The idling stop system for scooters employs an ACG starter connected directly to the crankshaft without reduction gears; therefore, it is possible to start the engine silently. The system is designed to stop the engine automatically when the scooter stops, and the engine restarts simply by opening the throttle. Scooters with 50 cm₃ engines have already been employing the idling stop system. This system for 125 cm₃ engines was developed to enlarge the application range of the idling stop system. It needs a large ACG starter because the cranking torque is higher than that of 50 cm₃ engines, so the cranking torque was reduced by using a decompression device. The ACG starter was designed with a thin and large diameter construction in order to minimize the increase in engine width. The new idling stop system was developed with an integrated control of the fuel injection system and the ACG starter.
