1. SEMINAR - 2012 DIGITAL TWIN SPARK IGNITION ENGINE (DTSi) Presented by:

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
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 plugs controlled by the microchip .

6. The working of Digital twin spark ignition in 4-stroke petrol engine shown in diagram

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.
