Abstract : The application of soft computing techniques for spark ignition (SI) engines improves the performance of the system. This paper presents the development of fuzzy logic based ignition control system for a single cylinder SI engine. The fuzzy logic controller (FLC) was designed and developed in Matlab. The inputs to the FLC are engine speed and throttle position and the output is spark angle value. The spark angle value obtained from the Matlab simulation for different engine speeds and throttle position conditions is found to be satisfactory. To validate the simulation results, the FLC is implemented in a microcontroller with ARM7TDMI core. It has been observed that the hardware results match the simulation results. As the control system is programmable, it could be used to enhance the performance of different engines.
