The DTS-i (digital twin spark ignition) system use in 4 stroke petrol engine . In INDIA this technology use in bajaj motors.

2. What Is DTS-i System
 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.

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

5. 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 .

Digital twin
spark ignition
in 4-stroke
petrol engine

7. Various functions of DTS-i system
 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.

8. Combustion Process In SI engine

9. What are the benefits of DTS-i system
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

10. Less vibrations and noise.
Long life of the engine parts such as piston
rings and valve stem.
Decrease in the specific fuel consumption.
No over heating.
Gradual increase in the pressure.

11. Disadvantages of DTS-i system
 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.
 DTS-i is actually a simpler, cheaper and low-tech alternative to
making more power and burning less fuel. However owners
mistakenly think it is high-tech.

12. bike in which we use the dts-i engine?
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.
