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.

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.
