Fuel Injection System for One Cylinder Motor Cycle Engine. Fuel injection has been developed for many years. Butits common application is limited on car's engine. With many reason fuel injection systems in motorcycle one cylinderengine has not been widely used yet. Fuel Injection System allows the amount of fuel, injected to be controlledappropriate to engine parameters such as engine speed, amount of air inducted to cylinder, temperature, for each cycle,over the entire engine operating conditions. This fuel injection research is done to find out the Volumetric Efficiency ofthe intake manifold system, the amount of fuel need to be injected for each engine cycle, and the engine characteristicsover variation of test conditions. This research based on Honda CB100 engine, at applied thermodynamic Laboratory ofMechanical Engineering Department, Faculty of Engineering University of Indonesia. Experiment data from thisresearch shows the characteristics of injector duration as functions of engine speed, intake pressure, on one cylinderengine and the results of this research shows a good Volumetric Efficiency of the intake manifold designed using CFD(Computational Fluid Dynamic).Keywords: fuel injection system for motor cycle,intake manifold, computational fluid dynami
