SECURITY ENABLED CAPACITIVE DISCHARGE IGNITION USING AVR MICROCONTROLLER

Abstract

Capacitive Discharge Ignition (CDI) or thyristor ignition is widely used automotive electronic ignition system. A general Capacitive Discharge Ignition module is composed of a small transformer, circuits for the purpose of charging capacitor, and generating triggering pulses and a voltage capacitor. An ignition key is being used to turn on and turn off ignition in motor vehicles and automobiles. Embedded system provide the opportunity to replace the need of ignition key in a better and secure manner with password based login interface to allow user to turn on and subsequently turn off ignition at the desired time.
