Contents
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
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
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
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.
Working of DTS-i system
DTS-i use in 4-stroke petrol engine . And each cylinder having two spark plugs.
The working of Digital
twin spark ignition in 4-stroke petrol
engine.
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
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
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
