ACKNOWLEDGEMENTI would like to express my gratitude to Dr.Abhijit Kumar Mandal, Dy.Director(tech.),GARC for all his suggestions and guidance during the learning and execution phases of the project that helped me in completing the project successfully. I express my deepest thanks to Mr.M.V.Ramachandran, Sr.Deputy Director & Head, GARC for providing me with all necessary resource and for his enormous support and encouragement. I also thank the Head of the Department, Automobile Engineering _________________ and Mr.G.Shivakumar, Veltech University for the support they have provided for the successful completion of the project.Last but not the least, I would like to acknowledge and thank my parents and friends for their encouragement and valuable advices.

ABSTRACTThe project mainly concentrated to switch off the ignition system of the two wheeler while engine is running at the idle condition. It is open loop system in which it monitor varies parameters of the two wheeler such as wheel speed,engine speed,gear position for the idle condition and hence switch off the ignition system and switch on the ignition system and starter motor after the actuation from the clutch by the driver.The idea of the project can be implemented in the various ways using digital electronics,digital logic electronics,digital signal processing,microprocessor and micro controller.

For the project pic microcontroller 16f887A is used as the control unit.intially embeddedSystem for the project is developed and then it is interfaced with the subsystems of the two wheelers such as ignition system and starter motor.

Keywords:pic microcontroller,starter motor,start stop system,optical encoder,hall effect sensor,ignition system,timer,comparator,relay driver,speed sensor,engine rpm,intcon register,intsen register,ccp module.
