Valve DriveValve Drive

Valves directly acts inV-configuration.

Valve timing Actuator operatesexhaust and intake valves.

At high and medium-highengine speeds, cylinder filling is

optimal.

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.

AdvantagesAdvantages

Increase theThermal Efficiency ofthe Engine.

Diameter of the flame increasesrapidly.

Twin Spark plugs reduces thesoiling of plugs.

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.
