INTRODUCTION Air Car- Powered by Air Engine. Having Emission Free Piston Engine using Compressed Air as

Fuel. Gasoline- Main source of Fuel, Very Expensive and Impractical

(Environmental Standpoint), Non- Renewable resource, it will eventually run out.

One possible alternative is the air-powered car. Air Powered Cars runs on Compressed Air instead of Gasoline. Powered by two cylinder compressed engine.

VEHICLE PARTS COMPRESSED AIR TANK Are Localized Underneath the Vehicle. This Compressed Air Storage System is Safe to Risk of

Explosion. Hold 90 cubic meters of air, compressed to 300 bars. Are the same tanks used to carry the liquid gas used by

buses for public transport. Are Designed and Officially approved to carry an Explosive

Product: Methane gas. Tanks are Not Made of Metals, Rather they are made

Of Carbon Fibers. So if Tanks Rupture, They would not Explode, Rather They

Would Crack

THE BODY Car Body- Built with Fiber and Injected Foam. Two main advantages: Cost and Weight. Sheet Steel-Low Cost than Fiber. Fiber is safer. It doesn’t cut like steel. Easier to Repair, glue, doesn’t rust.

THE AIR FILTER Air- Compressed by On Board Compressor Or Service

Stations Equipped with High-Pressure Compressor. Before compression, Air must be Filtered to get rid of any

Impurities. Carbon Filters are used to Eliminate dirt, dust, humidity and

abundant abrasive particles. System eliminates and reduces existing Pollution. The Exhaust pipe on the Air-Powered Cars produces clean air

which is cold on exit (between 15o and 0o) and harmless to human life.

The air that comes out of the car is cleaner than the Air that went in.

THE CHASSIS Chassis- Highly resistant, Light, Aluminium Rods glued

together. Aluminium rods Enables to build More Shock-Resistant

Chassis than Regular Chassis. The rods are Glued in the Same way as Aircraft. Allowing quick assembly. More secure join than Welding. This System helps to reduce Manufacture Time.

TECHNOLOGY DESCREPTION

Piston 1- Takes in Air, Compresses at 300 psi & 200 *F in Compression Chamber During 1st Cycle of Engine.

Piston Pauses. Small Amount Of Air is released in Expansion Chamber. It Creates Low Pressure of 140 psi, Low Temperature, Low volume.

A High Speed Shutter Connects the Compression & Expansion Chamber.

Sudden Pressure & Temperature Difference in the two Chamber creates Pressure Wave in Expansion Chamber, Thus Producing Work that drives the piston to Power the Engine.

BASIC PRINCIPLE Uses an Innovative System to Control the Movement of the

Second-Generation Pistons and one single crankshaft. The pistons work in two stages and one intermediate stage of

compression and expansion. Engine has two functions: To compress ambient air. To make successive expansions thereby approaching isothermic

expansion.

WORKING Compressed air- Stored in Fiber or Glass Fiber Tanks at

a Pressure of 4500 psi. Fed through Air Injector to the Engine & flows into a

Small chamber, where Expansion occurs. Air Pushes the Piston down & moves the Crankshaft,

which gives Power. Car can run on Traditional Fuel in Combination with Air. The change of energy source is controlled

electronically. Car Speeds- <60kph,it runs on air. >60kph it runs on a

fuel such as gasoline, diesel or natural gas. Tank can be refilled at the nearest Air Pump. Car motors require a small amount of oil (0.8 litres)

that has to be changed just every 50,000km.

ARTICULATED CON-ROD The Con-Rod System- Allows the Piston to be held at Top

Dead Centre for 70% of the cycle. This way, enough time is given to create the pressure in the

cylinder. The torque is also better so the force exerted on the

crankshaft is less substantial than in a classic system.

GEAR BOX Gear Changes are Automatic, Powered by an Electronic

system. A computer which controls speed of the car is effectively

changing the gears.

MOTO-ALTERNATOR The Moto-alternator connects the engine to the gearbox. It has many functions: Supports the vehicle’s motor to allow the Tanks to be

refilled. As an alternator to produce Brake Power. Starts the Vehicle and Provides Extra Power when necessary.

ADVANTAGES Fast recharge time. Long storage lifetime Of Air. Potentially lower initial cost than battery electric vehicles

when mass production takes place. A Pure Compressed Air Vehicle produces no pollution at

the tailpipe. The compressed air engines also offer drivers the option of

using fossil fuels or bio-fuels to heat the air as it enters the engine.  

Air cars are lighter than conventional cars.

DISADVANTAGES When Compressor runs on Gasoline, it will create Pollution. One-to-two hour Waiting for the Car's built-in Air

Compressor to Compress air could become a problem on cross-country trips.

The distance that an Air Car can cover without refueling is crucial because very few filling stations will have compressed air pumps available.

CONCLUSION

Air powered cars is a Realization of latest technology in automobile field.

It eliminates the use of Non-Renewable fuels. Prevents Pollution caused by Millions of Automobiles

all over the world. This could be the future of automobiles and step to a

Healthier Environment.
