- 1. A SEMINAR ON DTS-I Technology Submitted to:- Submitted by:- Mr.Prashant Sharma Aniket Bose (Asst. Prof. Mechanical engg.) (Mechanical engg. 7th sem) (Roll no.-0202meo81005)
- 2. DTSI - digital twin spark ignition technology. We know that in petrol engine we require spark plugs to initiate ignition of A/F mixture. In DTSI instead of one sparkplug we have two plugs. More over when these sparkplugs should initiate the spark is determined by microcomputers. In India it was Bajaj who are having patents for their 150-220CC bikes
- 3. IN DIGITAL TWIN SPARK IGNITION SYSTEM TWO SPARK PLUGS ARE USED, CONTROLLED DIGITALLY ; BY A MICRO PROCESSOR. THESE SPARK PLUGS IGNITE THE FUEL MORE EFFICIENTELY AT THE AND OF COMPRESSION STROKE .
- 4. Twin spark plugs Digital C.D.I. TRICS III
- 5. TWO SPARK PLUGS ARE USED INSTEAD OF ONE ENABLES FAST AND EFFICIENT COMBUSTION LEADING TO BETTER FUEL EFFICIENCY AND HIGHER POWER AS COMPARED TO CONVECTIONAL ENGINES. BECAUSE THE IGNITION RATE IS DOUBLE; THE POWER IS GENERATED MUCH FASTER AND AFTER COMBUSTION PRODUCT AND GASES EXPANDS MORE FASTER WHICH IN TURNS PUSH THE PISTON MORE POWERFULLY AND WE GET BETTER PICKUP AND BECAUSE APPROXIMATELY ALL THE FUEL BEING IGNITED AT ONCE WE GET BETTER FUEL EFFICIENCY AS WELL.
- 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. 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. Performance DTS-I Regular Power 13.02Ps 12Ps Torque 11.68 Nm 10.08 Nm Max. speed 120 100
- 9. a) The fuel efficiency got drastically improved b) The power weight ratio improved
- 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 Honda's iDSI Vehicle engines use a similar arrangement of two spark-plugs.
