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.

2.LITERATURE REVIEW

1. 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.

2. Later above model was sold in India in 1995

and this technique was used by Bajaj Auto.

and had their patent

3. Combustion Process In SI

engine

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

4.1 DTS-i use

in 4-stroke

petrol

engine . And

each cylinder

having two

spark plugs.

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

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.

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 .

There are some advance technology used in DTS-iengine which makes it more powerful than the conventional single sparkplug 4-stroke engine like

1. Trics III technology (Throttle Responsive Ignition control System 3rd generation)

2. CDI technology

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 .

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.

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

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

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,

XCD125,135, DISCOVER150 , ETC. are

using the dts-i (digital twin spark ignition

system). which means the petrol enters

into the cylinder burns more efficiently.

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.
