• The first mechanically-propelled 2-wheel vehicle
may have been built by Kirkpatrick MacMillan in
1869.

Main characteristics:
•Digital electronic ignition with two plugs
per cylinder and two ignition distributors
•Injection fuel feed with integrated electronic twin spark ignition; •A high specific power; Compact design and Superior balance
IN SMALL ‘CC’ ENGINE, PULSAR DTSI IS THE FIRST BIKE IN THEWORLD TO HAVE TWIN SPARK -IGNITION SYSTEM.

WorkingThere are advance technology
used in DTSI engine which makes
it more powerful than the
conventional single sparkplug 4-
stroke engine like Capacitor discharge ignition

Advantages of using Twin
Spark:
Less vibrations and noise
Long life of the engine
parts such as piston rings
and valve stem.
Decrease in the specific
fuel consumption
No over heating
Increase the Thermal
Efficiency of the Engine &
even bear high loads on
it.
Disadvantages of using Twin
Spark:
If one spark plug get damaged
then we have to replace both
The cost is relatively more
The engine tends to overheat and
loose power at higher speeds as
compared to a single plug
engine.
In case the Engine is kept unused
for a long time soiling of spark
plugs occur. Twin Spark system
helps to reduce this problem.
