 IDLE STOP START SYSTEM ;

i3s stands for 'idle stop start system'. stop start system combine smart electronic controls with a more robust battery,alternator and starter system.The term idle is used because when our machine is in idle condition, this system automatically shuts off the machine and thus improves efficiency and reduce power waste.

all these systems work similarly and are ubiqui­tous on hybrids. When the car comes to a stop, the engine computer cuts spark and fuel. When the driver lifts his foot off the brake, or engages the clutch, the engine fires back up.

Of course, the starter has to be stout enough to withstand the dramatically increased on-off cycling. A heartier battery is also required to ­satisfy the car’s entire electrical needs with its engine off. Otherwise, stop-start is about as easy a fuel-saving technology as driving downhill.

Eg: This technology is developed by Hero MotoCorp and implemented in Hero Splendor iSmart bike. This system automatically switches off the engine and switches back on when you press the clutch. When you stop the bike; the i 3S system puts the engine into hibernate or sleep mode. The Idle Stop Start Systemturns off the engine after waiting for about 5 seconds for e.g. at a traffic signal. The system then restarts the engine automatically as soon as you press the clutch without having the need to follow the routine procedure to start. This prevents running of the engine in idling when not needed and thus improves mileage.
