Brief working of the system
Turns off the engine when the vehicle stops for a short interval of time especially in traffic congestion or in traffic signals
Engine get restarted automatically when the vehicle is ready to move.
Achievable ImprovementsIncreased fuel economy
Decreased emissions

Temperature sensorsTo record the temperature in various
parts with the assistance of respective temperature sensors
Will help engine to avoid cold start by maintaining Engine in the apropos temperature range
Position sensorsTo find the positions of key parts of the
vehicleBrake pedal and acceleration pedal
positions helps the system to ensure that the engine is at rest or in motion.
Clutch pedal position and gear shift to find whether the car is in gear or neutral
Other sensorsWheel speed sensor to measure the speed
and to send appropriate signal to the system
Battery status sensor to signal the system about the back up in the battery which is mandatory to restart the engine comfortably
Seat belt connection sensor is to ensure safety
