3. 1. Introduction Digital Twin Spark Ignition has two spark plugs that use to ignite the charge in the combustion chamber. 2 spark plugs at either ends of the  combustion chamber help in faster and better combustion. It only use in the petrol engine.

4. 2 .LITERATURE REVIEW Alfa Romeo Twin Spark (TS) technology was used first time in Alfa Romeo Grand Prix car in 1914. Alfa Romeo incorporated this technology into their road cars to enhance their performance and to comply with stricter emission controls . Later above model was sold in India in 1995 and this technique was used by Bajaj Auto. and had their patent

5. 3 . Combustion Process In SI engine

6. 4 .Why do we use the DTS- i in 4-stroke Petrol Engine In 4-stroke petrol engine at ignition time the air and fuel mixture does not burn completely. But when DTS- i system use in engine the rich mixture completely burn and the ignition time decrease. And power of engine increases

7. 4 .1 DTS- i use in 4-stroke petrol engine . And each cylinder having two spark plugs .

8. 5 .DTS-I Engine Element The construction of DTS- i engine is same as that of the conventional 4-Stroke engine. It consists of following parts: Piston Cylinder Crankshaft Connecting rod

9. Fly wheel Carburettor 2-sparkplug 2-valves Here the only change made is that the 2 sparkplug placed at the two opposite end of the combustion chamber At 90 degree to each other .

10. 6 .Working of DTS-I system When the rich mixture of air and fuel enter in the combustion chamber , the two spark plugs fixed at opposite end of engine cylinder generated spark and this spark burn the mixture that burned mixture gives power to the 4-stroke engine. Here spark generated by the microchip .

11. There are some advance technology used in DTS- i engine which makes it more powerful than the conventional single sparkplug 4-stroke engine like 1. Trics III technology (Throttle Responsive Ignition control System 3 rd generation) 2. CDI technology

12. 6 .1 TRICS III Throttle Responsive Ignition Control System 3rd generation. It is a means of controlling the Ignition by operating the Throttle. Based on a particular amount of Throttle opening, the Magnetic field generated by the Magnet ,Which opens or closes the switch . The switch is connected to the Digital CDI, which signals the CDI to change the desired Ignition Advance .

13. 7. Revolution in DTS-I Technology “DTS-I Triple” spark technology that Bajaj employs on the new “Pulsar 200NS”. The “Pulsar 200NS” an engine that has the world’s only first 3 spark plugs for its single cylinder. The 3 spark plugs make for efficient burning of the “air + fuel ” mixture which benefits and enhances .

15. 8 . Advantages of DTS- i system Less vibrations and noise Ignition time decreases. Long life of the engine parts Decrease in the specific fuel consumption Better starting of engine even in winter season & cold climatic conditions s

16. 9 . Disadvantages of DTS- i system The engine tends to overheat and loose power at higher speeds as compared to a single plug engine. There is high NOx emission If one spark plug get damaged then we have to replace both . The cost is relatively more

17. 10 . Bike in which we use the DTS- i engine? In India Bajaj has patented for dts-i technology . At present Such as PULSAR 135,150,180,200,200NS, 220 , PLATINA, XCD 125,135 , DISCOVER150 , ETC. are using the dts-i (digital twin spark ignition system). which means the petrol enters into the cylinder burns more efficiently.

18. 11. Conclusion Perfect Combustion in Internal Combustion engine is not possible due to the various losses. So for the instantaneous burning of fuels in I.C. engine, Digital Spark Ignition system can be used which produces twin sparks at regular intervals that can help to complete the combustion.
