i3S: What does it mean and How this Technology Works

by Pooja Late so cut

i3s stands for Idle Stop-Start System. Hero MotoCorp developed this technology to improve the mileage of its bikes under the Indian Driving Conditions

How does the i3s system Work?

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 simply press the clutch. When you stop the bike the i3S system puts the engine into hibernate or sleep mode.

The Idle Stop-Start System turns 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. So when the rider wants to go, the engine starts by simply pressing the clutch again; that's it. You don't have to follow the routine procedure to re-start it. This prevents running of the engine in idling when not needed. Thus, it improves mileage.

The i3s technology was specifically put together by Hero Moto to address the fuel consumption rates in two-wheelers. The i3s unit presents itself in the form of a rider selectable on-off switch located on the right handlebar of the Hero Splendor. A simple push of this button triggers the stop-start system. After a brief period of idling, the engine switches off automatically and springs back to life once the clutch lever is engaged.

This is valuable to the rider in many ways. Long waits at traffic signals with your motorcycle engine running can not only waste fuel but also detriment the air levels surrounding you. Also, allowing your engine to run for prolonged durations in jam-packed roads and junctions can cause air-cooled engines to heat up rather quickly and increase the temperature levels around your vehicle. The i3S technology solves these issues, thereby improving mileage, reducing emissions, and extending engine life.

A smart inclusion to the motorcycle segment definitely, but the entire system places heavy dependence on the condition of the battery and the electric starter. This technology works only on bikes that have an electric starter and requires the battery to be in pristine working condition at all times.
