PRESENTATION ON DIGITAL TWIN SPARK
. IGNITION (DTS-I)
Under the guidance of,
1. DTSi stands for Digital Twin Spark Ignition.
Digital Twin Spark Ignition has two spark plugs
that use to ignite the charge in the combustion
2.Twin spark plugs at either ends of the
combustion chamber help in faster and better
combustion. It only use in the petrol engine.
Why Use of DTS-I in 4-stroke
• In 4-stroke petrol engine at ignition time
the air and fuel mixture does not burn
But when DTS-i system use in engine the
rich mixture completely burn and the
ignition time decrease and power of
DTS-i use in
engine . And
Working of DTS-I system
When the rich mixture of air and fuel
enter in the combustion chamber , the two
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.
of Digital twin
Various functions of DTS-i
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
It use to increase the power output of engine.
Combustion Process with DTS-I
The fresh charge that entered the cylinder
during the suction stroke is compressed during
the compression stroke.
Then a spark will be ignited by one of the Twin
spark plugs and the flame front begins to
expand like an inflating balloons.
Advantages of DTS-I
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
Disadvantages of DTS-i
If one spark plug get damage then we have to
The engine tends to overheat and loose power
at higher speeds as compared to a single plug
There may be a kind of knocking sound on the
DTS-i is actually a simpler, cheaper and low-
tech alternative to making more power and
burning less fuel.
DTS-I Technology used by company
It is a BAJAJ Auto Tredmark. In india bajaj has
patented for dtsi technology . At present
135,150,180,200,220 are using the dtsi (digital
twin spark ignition system).
Hence it can be concluded that the
of these technologies in the present day
automobiles will give present generation
what they want i.e power bikes with fuel
