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.
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.
DIGITAL TWIN SPARK ignition engine has two Spark plugs located at opposite
ends of the combustion chamber and hence fast and efficient combustion is obtained. The
benefits of this efficient combustion process can be felt in terms of better fuel efficiency and
lower emissions. The, ignition system on the Twin spark is a digital system with static spark
advance and no moving parts subject to wear. It is mapped by the integrated digital electronic
control box which also handles fuel injection and valve timing. It features two plugs per
cylinder.
This innovative solution, also entailing a special configuration of the hemispherical
combustion chambers and piston heads, ensures a fast, wide flame front when the air-fuel
mixture is ignited, and therefore less ignition advance, enabling, moreover, relatively lean
mixtures to be used. This technology provides a combination of the light weight and twice the
power offered by two-stroke engines with a significant power boost, i.e. a considerable
"power-to-weight ratio" compared to quite a few four-stroke engines. Fig.1. show the actual
picture of Bajaj Pulsar Bike.
Ignition
The, ignition system on the Twin spark is a digital system with static spark advance and no
moving parts subject to wear. It is mapped by the integrated digital electronic control box
which also handles fuel injection and valve timing. It features two plugs per cylinder. Fig. 3
shows the starting circuit of Pulsar DTSI Bike.
This innovative solution, also entailing a special configuration of the hemispherical
combustion chambers and piston heads, ensures a fast, wide flame front when the air-fuel
mixture is ignited, and therefore less ignition advance, enabling, moreover, relatively lean
mixtures to be used.
Conclusion:
From this paper I have concluded that perfect Combustion in Internal Combustion engine is
not possible. So for the instantaneous burning of fuels in I.C. engine twin spark system can be
used which producing twin sparks at regular interval can help to complete the combustion.
