⮚ Every day in our life, we observe different technologies in bikes and they will be shown as shortcuts like DTSI,
DTS-SI, APDV, ASFS, and ATFT; then we feel very enthusiastic to know
⮚ All these DTSI, DTS-SI, APDV, ASFS, and ATFT are the technology updations in the bikes that will give a good
engine performance and even mileage performance.

• DTS-i stands for Digital twin spark ignition . Digital Twin Spark Ignition has
two spark plugs that use to ignite the charge in the combustion
chamber.
• Twin spark plugs are used at either ends of the combustion chamber helps in
faster and better combustion
• It only used in the 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.
• DTS-i use in 4-stroke petrol engine . And each cylinder having two spark
plugs

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 is generated by the microchip .

• It use to increases the efficiency .
• It use for faster and better combustion.
• It has two spark plug , so it burns the complete rich mixture (air and
fuel) in 4stroke petrol engine.
• It use to increase the power output of engine.

• Ignition time decreases.
• The rich mixture (air and fuel) completely burns in combustion chamber
• Power produced by DTS-i more compare to single spark ignition system.
• Increase the pick up of engine
• Less vibrations and noise.
• Long life of the engine parts such as piston rings and valve stem.
• Decrease in the specific fuel consumption.

DISADVANTAGES OF DTS-i TECHNOLOGY
• If one spark plug get damage then we have to replace both.
• The engine tends to overheat and loose power at higher speeds as compared to
a single plug engine.
• There may be a kind of knocking sound on the machine.
• Cost increases due to additional technology

DTS-I Technology used by company
It is a BAJAJ Auto Trademark. In India Bajaj has patented for dtsi technology .
At present platina,xcd125,135,discover150,pulsar 135,150,180,200,220 are using
the dtsi (digital twin spark ignition system) which means the petrol enters into
the cylinder burns more efficiently.

Advancement of DTS-I Technology
Engine can be further turned to deliver better performance or better mileage. The
further advances of DTS-I technology are :
•Digital Twin Spark- Swirl Induction (DTS-Si)
•Digital Twin Spark- Fuel Injection (DTS-Fi)

Digital Twin Spark Ignition- Swirl Induction
(DTS-Si)
• The Swirl Induction Concept, which is meant for producing high turbulence in the
combustion chamber
• Swirl Induction is nothing but imparting a swirl motion to the fresh charge that
enters the combustion chamber

Digital Twin Spark Ignition-Fuel Injection
(DTS-Fi)
• DTS-Fi is another advancement of parent DTS-I Technology.
• This technology is a combination of both DTS-I and fuel injection.
• This technology is meant for increasing the fuel efficiency in power
bikes.

Hence it can be concluded that the application of these technologies in the present
day automobiles will give present generation what they want i.e power bikes with
fuel efficiency.
