Please Pay AttentionsPlease Pay Attentions Research studies show that under-inflated tires are a major issue

today.

In the USAIn 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 EUIn 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 StatisticsSome Other StatisticsA 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.

GM offered these in CUCV(Commercial Utility Cargo Vehicle) Blazers and pickups used by U.S. military.

SELF-INFLATINGSELF-INFLATING SYSTEMSSYSTEMS

Detect when the air pressure in a particular tire has dropped

Notify the driver of the problem

Inflate that tire back to the proper level

Tire-inflation systems have three general goals:

PARTS OF SELF-INFLATING PARTS OF SELF-INFLATING SYSTEMSYSTEM

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.

TIRE MAINTENANCE SYSTEM (TMS)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.

11

AIRGO SYSTEMAIRGO SYSTEM1. 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
