Abstract:
It is very interesting to know about complete combustion in automobile engineering. Because
in actual practice, perfect combustion is not at all possible due to various losses in the
combustion chamber as well as design of the internal combustion engine. Moreover the
process of burning of the fuel is also not instantaneous. However an alternate solution to it is
by making the combustion of fuel as fast as possible. This can be done by using two spark
plugs which spark alternatively at a certain time interval so as increase the diameter of the
flame & burn the fuel instantaneously. This system is called DTSI (Digital Spark Ignition
system). In this system, due to twin sparks, combustion will be complete.
This paper represents the working of digital twin spark ignition system, how twin sparks are
produced at 20,000 Volts, their timings, efficiency, advantages & disadvantages, diameter of
the flame, how complete combustion is possible & how to decrease smoke & exhausts from
the exhaust pipe of the bike using Twin Spark System.

Introduction:
A conventional 4 Stroke engine has a Single Spark Plug located at one end of the combustion
chamber and hence the combustion is inefficient leading to sub optimal mileage and sub
optimal performance & can even have problems with oil flow. Hence forth there was a
requirement to change engines' design, fuelling, ignition, production and quality to achieve
the following objectives.
- Uniform power delivery in all operating conditions;
- A high degree of drivability;
- First rate standards of reliability;
- Long service life.
With a view to overcome the above limitations a new patent was introduced that is known as
DTS-I technology & its use is increasing day by days.
