PRESENTATION ON DIGITAL TWIN SPARK . IGNITION (DTS-I)

By,Mr.)

Under the guidance of,Prof.

.

DTS-i Technology

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 chamber.

2.Twin spark plugs at either ends of thecombustion chamber help in faster and better combustion. It only use in the petrol engine.

Why Use of 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.

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.

Various functions of DTS-i Technology

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.

Combustion Process with DTS-I Technology

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 Technology

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 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.

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 platina,xcd125,135,discover150,pulsar 135,150,180,200,220 are using the dtsi (digital twin spark ignition system).

Conclusion….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.

Thank you…..
