Decreasing of the Engine Idle Speed of a Small Gasoline Engine with Feedback Control 2009-32-0171

This study proposes a method of decreasing the engine idle speed for the engine of FSAE race car. In general, the engine is controlled by map-based method. However, this method requires much time and cost to create a fuel injection map and an ignition timing map [1]. In addition to this, creating these maps at idle speed is much harder because the engine speed is cranky at idling. In this study, ON/OFF control and PID control were used for idle speed control without creating maps. As a result, idle speed was decreased drastically compared with map-based control. The PID control was able to stabilize the idling compared with the ON/OFF control.
