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.
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.
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.
