3. Existing Technique
1.An internal regulator senses when the tire inflation pressure has dropped below the optimum pressure. The regulator then opens to allow air flow into the pum ping tube
2.As the tire rolls, the deformation of the tire flattens the tube, pushing the air through the tire to the inlet valve
3.The air flows into the tire cavity,resulting in optimized tire pressure
NOTE:CODA Industries in germany, holds patent for this technique.

4. Improvements made in the existing technique
Inflating and deflation is done in lesser time due to temperature of exhaust gases.
Improvements made in the existing technique
1.Quick Inflation

5. 2. Deflation
Deflation is done by the user, using the digital display system,Which operates based on the sensor signals.

6. What is the need of this technique?
Improved safety: Estimated that 41% of accidents with physical injuries are linked to tire problems. Under-inflated tires lead to tread separation and tire failure, resulting in 40,000 accidents, 33,000 injuries and over 650 deaths per year
Increased Fuel Efficiency:The European Union reports that an average under-inflation of 40 kPa produces an increase of fuel consumption of 2% and a decrease of tire life of 25%.
Reduced pollution: The European Union concludes that tire under-inflation today is responsible for over 20 million liters of unnecessarily-burned fuel, dumping over 2 million tonnes of CO2 into the atmosphere, and for 200 million tires being prematurely wasted worldwide.

7. How proposed technique differ from existing technique?
Time taken for inflation is high.
Time taken for inflation is low.
Deflation is not done.
Deflation is done,whenever required(slopy areas).
Accident is possible in low friction (between tyre and road) areas due to high inflation.
Accidents due to slippery roads are reduced.
Atmospheric air is used for inflation of tyres.
Exhaust air,is used to provide effective inflation.

8. Market Overview Low production costs Higher profit margins
The Proposed  system is very simple and easy to integrate into the current tire manufacturing process. It consists only of two new tire components:
Peristaltic tube chamber integrated into the tire wall.
Automatic pressure regulator with interface connecting the tire interior with outside environment.
Production of ISIT tires will be only marginally more expensive than the production of today’s regular tires.
A copper Intercooler is used for cooling purpose.
Higher profit margins
Low costs and a high added value create room for increase of profit margins.

9. Target Customers:
1.People using automotive in hilly areas.
2.Goods loading vehicles used for transportation.
3.Vehicles in abroad.
Future plans:
Militiary vehicles with bullet resistant tyres can be made by improving this technique at a marginal manufacturing cost
