Introduction
Research studies show that under-inflated tires are a major issue today.
In the USA
27% of passenger cars and 32% of light trucks have at least one tire under pressured by more than 25%. This results in 1.24 billion gallons of wasted fuel per year (costing 3.7 billion USD).
In the EU
38% of cars in the EU drive on under-inflated tires. This results in 5.3 billon liters of wasted fuel worth of 7 billion EUR, and an extra 12.3 million tons of CO2 released into the atmosphere.
So, we can say that we require a system is easy and inexpensive to produce would bring enormous savings in fuel, pollution, and human lives when implemented on a large scale.
Some Other Statistics
A statistics show that tires which are under inflated by as little as 2 psi reduce fuel efficiency by 10 percent.
Over a year of driving, that can amount to several hundred dollars in extra fuel purchases.
One of reason for Road Accident is less or Insufficient Tire Pressure.
Near about 10,000 injuries could be prevented per year if all vehicles were equipped with tire pressure monitoring systems.
PARTS OF SELF-INFLATING SYSTEM
Tire deflation valves
Tire inflator hoses
To operate tire deflation valve this is screwed onto the existing tire valve. It inflates the tire to a required pressure
CTIS: INSIDE
Wheel Valve
ECU
Pneumatic Control Unit
Control Panel
Speed Sensor
Pressure Switch
TIRE MAINTENANCE SYSTEM (TMS)
Similar to CTIS
It notifies the driver via warning light(visible in rear mirror).
After every 10 min. or time period specified system check the tire pressure
AIRGO SYSTEM
When a tire loses pressure, due to a puncture or other seepage, a series of check valves automatically detects it.
2. The System then immediately draws air from the vehicle’s pneumatic system and directs it to each tire requiring air.
3. The air pressure is delivered via the trailer’s hollow axle housing.
4. The air then goes through the hub assembly and into the tires. It is completely isolated from the brake system
Conclusion
Increases safety, comfort and fuel efficiency
Flexibility for drivers
Future tires
Better option to reduce road accidents
