This document summarizes a seminar presentation on Idle Stop Start (I3S) technology. I3S technology automatically shuts off the engine when idling to reduce fuel consumption and emissions. The technology was first developed by Toyota in 1964 and has improved fuel economy by about 10% according to tests. I3S works by using a battery, electric generator, starter, and sensor to restart the engine within 350 milliseconds when needed. I3S reduces fuel consumption by 5-10% in city driving and lowers CO2 emissions by 7-8%. While the technology cuts costs and emissions, it provides only minor fuel savings compared to hybrid systems and some vehicle functions may not work with the engine off. I3S

3. Introduction
• I3S means Idle Stop Start System.
• It is a green technology that automatically
shuts engine when idling and turns it on when
needed.
• It reduces the fuel consumption effectively
and efficiently.

4. History
• It is first developed in 1964 by Toyota.
• Testing of it shows about 10% improvement in
fuel economy.
• Four wheeler having this technology were the
Fiat Regma “ES” and Volkswagen Polo “Formel
E”.
• Firstly in Hero motorbike in 2013.
• Two wheeler having this technology were
Hero splendor i-smart , new passion pro.

5 I3S TECHNOLOGY
(2015)
Pradip Arun Manatkar,
Darshan Ramrao Rathod,
Minal Gangadhar Bhugul
As mileage of the Hero Splendor i-
smart is greater than other bikes
having same cc engine cylinder.
just only because of
implementation of I3S technology

7. Problem Statement
• Less mileage of vehicles.
• More CO2 emission causes pollution.
• More fuel consumption.
• More engine noise and vibration when in
standstill condition.
• More usage of fuel during idle running of engine.

8. Working in two wheeler

10. • It uses battery, electric generator ,electric
starter, Electronic Control Unit (ECU), speed
sensor.
• It uses regenerative braking, where rotational
energy of wheel turns the electric generator
and generates electricity.
• When speed is 0 km/hr, sensor sense and
sends the signal to ECU then 1 min timer get
started and after 1 min ECU shuts the engine.
• With the help of ECU it uses generated energy
to start the engine when clutch is pressed.

11. Block diagram of I3S technology

12. Conditions to stop the engine automatically:
• Vehicle speed is zero.
• Gear box in Neutral.
• I3S feature should be on.
Conditions to start the enigine automatically:
• Engine speed is zero.
• Vehicle speed is zero.
• Gear box is in Neutral.
• I3S feature is should be on.
• Clutch is pressed fully.

13. Advantages of I3S technology
• Fuel consumption is reduced by up to 5% -
10% in city driving.
• CO2 emissions are reduced by up to 7% - 8%
• Engine restarts within 350 milliseconds and in
complete silence.
• Implementation cost is not very high.
• Engine stops and starts automatically.
• Eliminates engine noise and vibrations.

14. Disadvantages of I3S technology
• Fuel saving is not as good as fully Hybrid.
• Some vehicle function may not run when
engine is off. ( e.g. Air conditioner in cars)
• In four wheeler it require special type of
battery and starter.
• Even though Implementation is cheap, vehicle
manufacturer will charge huge amount for
vehicles with I3S system.

15. Application
• Hero splendor i-smart bike.
• New passion pro
• Mahindra and Mahindra has introduced the
stop start based Micro Hybrid system.
• Fiat introduced this system in inflate 500.
• Volkswagen polo , golf & Passat.
• Many BMW cars

16. Conclusion
• More than 50% of the newly registered
vehicles will have start-stop as standard
technology after 2013.
• This system raises the alarm to the society to
cut CO2 emission, save fuel and preserve the
nature .
• This is very cost effective system useful in two
wheelers to save fuel, CO2 emission, nature
and global warming.

18. FUTURE SCOPE
• As it is less costly to implement in a bikes or in
cars, so can be implemented in most of the newly
manufactured vehicles.
• With the use of this technology in maximum
vehicle, emissions and noise will reduced up to
certain extent and helps to maintain green
environment.
• As it improves mileage it helps in minimum
usage of fuel so decreasing demand of fuel up to
certain extent.
