Description:Recently launching engine powered vehicles were equipped with electronically controlled both fuel supply and ignition systems. Engine Electronic Control Unit (ECU) which controls an engine with control sensors and actuators. The crank (or) cam sensor signal information is required to control fuel injection and ignition timings.
In almost all vehicles, both fuel injection and ignition timings were controlled with single ECU circuit hardware part. It is costlier to replace an entire control hardware part, if only ignition related part of the circuit is damaged. To avoid huge expenses while replacing an entire part of ECU when only ignition part of the circuit is damaged, one can use additionally the cheaply designed ignition driver circuit to operate the ignition system. Also, the maintenance of the cheaply designed ignition timing driver circuit is cheap.

OBJECTIVES OF INVENTION
1. The designed part of electronically controlled ignition driver circuit is cost benefitive one (cheap).
2. To avoid huge cost while replacing entire ECU, if only ignition control related part of the circuit is damaged.

SUMMARY OF INVENTIONS
The COP (coil on plug) type ignition coil is the actuator used to control ignition triggering time through L298N motor driver circuits. Arduino UNO is used as a controller board to control the ignition timing with input signal from crank (or) cam sensor.
Arduino coding was developed to control ignition timing through COP type ignition coil using signal input source from crank (or) cam sensor.
, Claims:1. The designed electronic ignition driver circuit is an innovative one which utilizes Arduino UNO as a controller, two numbers of L298N motor driver circuits, 12V relay and 20A fuse.
2. The developed Arduino coding is newer and fed into the controller. The controller which receives signal input from crank (or) cam position sensor and sends the output signal to COP type ignition coil.
3. The designed electronic ignition driver circuit is very cheaper than any other developed ignition drivers.
4. It is easy to replace the faulty ignition related part of an ECU while using the cheaply designed/developed ignition driver circuit additionally without replacing entire part of an ECU.
