AdvantagesAdvantages
Better starting of engine even in Winterseason & cold climatic conditions.
Due to two spark plugs, there will besufficient time intervals to cool the
chamber.
Efficiently balances the temperature of
chambers and other parts.

IgnitionIgnition
It is controlled by integrated digitalelectronic control box called
CapacitorDistributed Ignition(CDI).
DTS-i yields:
1. More effective combustion at lowload and at idling speed.
2. A sizeable reduction in specific
fuel consumption.
3. Less chance of ignition system
failure.

DisadvantagesDisadvantages
The engine tends to overheat and loosepower at higher speeds.
Requires more investment for replacingthe plugs.
The engine wear and tear is somehowincreased and hence these engines need
frequent checkup.

So, finally I conclude..So, finally I conclude..
Perfect Combustion in Internal Combustionengine is not possible.
DTSI system helps for instantaneousburning of fuels.
To overcome the requirements, newpatentDTS-i is introduced.
