  1. 1. A SEMINAR ON DTS-I TechnologySubmitted to:- Submitted by:-Mr.Prashant Sharma Aniket Bose(Asst. Prof. Mechanical engg.) (Mechanical engg. 7th sem) (Roll no.-0202meo81005)
  2. 2. DTSI - digital twin spark ignition technology. Weknow that in petrol engine we require spark plugs toinitiate ignition of A/F mixture. In DTSI instead of onesparkplug we have two plugs. More over when thesesparkplugs should initiate the spark is determined bymicrocomputers. In India it was Bajaj who are havingpatents for their 150-220CC bikes
  3. 3. IN DIGITAL TWIN SPARK IGNITIONSYSTEM TWO SPARK PLUGSARE USED, CONTROLLED DIGITALLY; BY A MICRO PROCESSOR.THESE SPARK PLUGS IGNITE THEFUEL MORE EFFICIENTELY ATTHE AND OF COMPRESSIONSTROKE .
  4. 4.  Twin spark plugs Digital C.D.I. TRICS III
  5. 5. TWO SPARK PLUGS ARE USED INSTEAD OF ONE ENABLES FASTAND EFFICIENT COMBUSTION LEADING TO BETTER FUELEFFICIENCY AND HIGHER POWER AS COMPARED TOCONVECTIONAL ENGINES. BECAUSE THE IGNITION RATE ISDOUBLE; THE POWER IS GENERATED MUCH FASTER ANDAFTER COMBUSTION PRODUCT AND GASES EXPANDS MOREFASTER WHICH IN TURNS PUSH THE PISTON MOREPOWERFULLY AND WE GET BETTER PICKUP AND BECAUSEAPPROXIMATELY ALL THE FUEL BEING IGNITED AT ONCE WEGET BETTER FUEL EFFICIENCY AS WELL.
  6. 6. To enable sparking of two spark plugs , a digital C.D.I. capable of handling this was developed.To enable optimum ignition timing for part throttle loads and full throttle loads . There are separate ignition maps stored in the memory of the C.D.I. These are activated depending on the throttle opening and engine speed.
  7. 7. To enable switching the required ignition maps , a magntically operated reed switch is incoporated on the carburettor throttle shaft and carburettor body . This is known as TRICS-III.Throttle responsive ignition control system – IIIrd generation.
  8. 8. Performance DTS-I RegularPower 13.02Ps 12PsTorque 11.68 Nm 10.08 NmMax. speed 120 100
  9. 9.  a) The fuel efficiency got drastically improved b) The power weight ratio improved
  10. 10.  Bajaj Auto holds an Indian patent for the DTSi technology. The Alfa Romeo Twin-Spark engines, the BMW F650 Funduro which was sold in India from 1995 to 1997 also had a twin- spark plug technology, and the Rotax motorcycle engines,more recently Hondas iDSI Vehicle engines use a similar arrangement of two spark-plugs.
