 Applications
 Digital twin spark swirl induction
 Conclusion

4. Introduction
 Introduced by BAJAJ in
India
 Incomplete combustion due to
speed of engine & design of
engine
 Spark is produced by two
spark plugs
 Generating two sparks at
upper end of the chamber

5. WHY IT’S CALLED DIGITAL
 Intelligent device – Electronic Control Unit
 controls the fuel ignition of fuel mixture
 Controlled based on
1.Load (throttle)
2.Engine rpm
3.Engine temperature
 controlled by microprocessor based system
 collects information from various sensors

7. COMBUSTION WITH DTS-I
 Two spark plugs maintain
90° to valve axis
 Flame travel will be high
 Two flames easily travel
in whole cylinder
 Flame travel reduction is
40%
 Complete combustion
 It causes more fuel
efficiency , more torque ,
lower emission

8. COMBUSTION WITHOUT DTS-I
 Incomplete fuel
combustion
 Spark ignition is delay to
reach the whole cylinder
 It causes slow &
inefficient combustion
 Emission is high

10. ADVANTAGES OF DTSI
 less vibrations & noise
 Long life of the engine parts
 Decrease in specific fuel consumption
 Increase the Thermal Efficiency
 Gradual increase in the pressure

11. DISADVANTAGES OF DTSI
 Maintenance of two spark plugs
 Cost increases
 Due to sparking needs to be cooled effectively
 Avoid soiling of spark plugs - unused for a long
time
 Replace both spark plug if one gets damaged.

12. APPLICATIONS
platina, xcd125, 135, discover150,
pulsar135, 150, 180, 200, 220 etc.

13. DIGITAL TWIN SPARK SWIRL
INDUCTION
 Producing higher turbulence in
the combustion chamber
 At light loads - improve the
combustion quality
 Achieved by modify
the port position

15. Conclusion
 More power bike with fuel efficiency
 Also minimize the
fuel consumption
harmful emission levels
 Solutions for increasing fuel costs
 Solutions increasing effect of global warming
