Control Device of Electronically Controlled Fuel Injection System of Air-cooled Engine for Small Motorcycle

Article of Honda R&D Technical Review Vol.16 No.1

Summary

In general, when an on board battery is low power, the electric power generated from an alternator by a kick-starter operation is consumed by all electrical loads including the battery. This causes a voltage drop. To eliminate the power shortage, an installed relay circuit opens all electric loads other than the fuel injection system. This allows the fuel injection system to use all electric power generated by the kick-starter. An electric power control system was incorporated into the ECU. The control system was realized that permits starting of an engine by using the kick-starter even when the battery is completely discharged. Also, by suitable sensing of engine oil temperature, the control system permits an efficient compensation of fuel injection quantity and ignition timing even in an air-cooled engine.
