3. Introduction I3S means I dle S top S tart S ystem. 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. H istory 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. Literature survey SR.NO PAPER TITLE AUTHORS CONCLUSION 1 A review on idling reduction strategies to improve fuel economy & reduce exhaust emissions of transport vehicles . (2014) I.Shancita , H.H Masjuki , M.A.Kalam , I.M. Rizwanul fattah , M.M. Rashed , H.K.Rashedul This study was conducted to determine the efficiency, advantages,and disadvantages of various technologies and their impact toward the minimization of fuel wastage and emissions from diesel- and gasoline powered vehicles. 2 Influence of the automotive Start-Stop system on noise emission.(2015) David Ibarra, Ricardo A. Ramirez-Mendoza, Edger Lopez, Rogelio Bustamante Results of the engine noise measurements of a gasoline vehicle, with the S/S system switched off and on, in a typical urban circuit of Mexico City

6. SR.NO PAPER TITLE AUTHORS CONCLUSION 3 Idling -stop vehicle road tests of advanced valve-regulated lead-acid battery.[2007] Ken Sawai , Takao Ohmae , Hironori Suwaki , Masaaki Shiomi , Shigeharu Osumi This paper has described an example of lead-acid battery performance in an idling-stop application. 4 Impact of idling on fuel consumption and exhaust emissions and available idle reduction technologies for diesel vehicles.[2013] S.M. Ashrafur Rahman , H.H. Masjuki , M.A. Kalam , M.J. Abedin , A. Sanjid , H. Sajjad This study was conducted to review effects on the emissions and fuel consumption of diesel engines when running in idling conditions, as well as to investigate viable alternatives to engine idling. 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

9. It uses battery, electric generator ,electric starter, Electronic C ontrol 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. W ith the help of ECU i t uses generated energy to start the engine when clutch is pressed.

10. Block diagram of I3S technology

11. 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.

12. 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.

13. 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.

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

15. 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 .

16. 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.
