The Microprocessor Control for the Air-fuel Ratio and Ignition Time of the Motorbicycle Engine

A micropocessor control system was introduced into the making of motorbicycle. In accordance with the various operating mode of engines, the system the appropriate signlas to adjust either air-fuel ratio or igniting time. The optimal control to the air-fuel ratio and duration of ignition was achieved. So the performance of motorbicycle engine can be improved greatly through the controlled air-fuel ratio and duration of ignition.
