DTS-i stands for Digital Twin Spark Ignition DTS-i has two spark plugs that use to ignite

the charge in the combustion chamber.2 spark plugs used at either ends of the

 combustion chamber help in faster and better combustion.

It is only used in the petrol engine.

Introduction

Page 4: Dts i - copy

In digital twin spark ignition system two spark plugs Are used, controlled digitally ; by a micro processor.These spark plugs ignite the fuel more efficiently at The end of compression stroke .

Working Principle of DTS-i System

Combustion Process In SI engine

Page 6: Dts i - copy

In 4-stroke petrol engine at time of ignition the air and fuel mixture does not burn completely. But when DTS-i system is used in engine the rich mixture is completely burnt and the ignition time decrease. And power of engine increases.

Importance of DTS-i in 4-stroke Petrol Engine

Page 7: Dts i - copy

When the rich mixture of air and fuel enter in the combustion chamber , the two spark plugs

fixed at opposite end of engine cylinder generates spark and this spark burns the mixture. That burned mixture gives power to the 4-stroke engine. Here spark is produced by spark plug and is controlled by by the microprocessor.

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

It is used to increases the efficiency . It used 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 is used to increase the power output of engine.

Various functions of DTS-i system

Page 11: Dts i - copy

In india bajaj has patented for DTS-i technology . At present platina,xcd125,135,discover150,pulsar 135,150,180,200,220 are using the DTS-i (digital twin spark ignition system). which means the petrol enters into the cylinder and burns more efficiently.

Bikes in which we now use the DTS-i engine

Ignition time decreases.The rich mixture (air and fuel) completely burns in

combustion chamber.Power produced by DTS-i more compared to single

spark ignition system. Increase the pick up of engineLess vibrations and noise.Long life of the engine parts such as piston rings and

valve stem.Decrease in the specific fuel consumption.Higher fuel efficiencyLess emission causing less pollution

Advantages of DTS-i system

Page 13: Dts i - copy

The engine tends to overheat and loose power at higher speeds as compared to a single spark plug engine.

There may be a kind of knocking sound on the machine.

Disadvantages of DTS-i system
