In order to achieve a good idle speed stability, emission and economic effect for spark ignition engine, the air-fuel ratio has to been controlled under idle conditions. In this paper, an engine model for a 125cc EFI motorcycle engine was established using the GT-power software, and a simulation and experimental study was performed when engine under idle speed condition. The result shows that there is a corresponding relationship between the idle speed and the air fuel ratio. An accurate control method for setting optimal working air-fuel ratio under idle speed condition can be obtained using the results of this study.
