Air powered cars use compressed air instead of gasoline to run. They store compressed air in high-pressure carbon fiber or glass fiber tanks at around 4500 psi. The compressed air is fed into an engine that drives the pistons to power the car. Air powered cars produce no emissions and could help address issues of declining fossil fuels and reducing pollution. Several companies are working to develop and produce air powered cars for the mass market within the next few years.

FUTURE TECHNOLOGY

 In modern technology
transportation is done with
fossil fuels .
( gasoline, petroleum……..)
 But the main flaw is we are
running out of fossil fuels due
to increase in population , the
effect is by 2035 we will run
out of all fossil fuels

3.  To overcome this we go for renewable energy
resources like sunlight , water , bio-gas etc.
 But solar panels are costlier now a days . That they
do not provide output to that of the conventional
energy .
 In fact water energy has the same flaws .

4.  Since the vehicle density increases day by day
, to avoid pollution and not to affect
transportation go for Air Powered cars .
 Which uses air as the source . Even though
air is an renewable energy resource we can
attain the specifications to that of the other
renewable energy cars .

5.  The first air car will almost certainly use the Compressed Air
Engine (CAE) developed by the French company, Motor
Development International (MDI).
 Most likely, it will be the e.Volution car that is being built by
Zero Pollution Motors

6.  Principle :
The law of physics dictate that
uncontained gases will fill any given space. The
easiest way to see this in action is to inflate a
balloon. The elastic skin of the balloon holds the
air tightly inside, but the moment you use a pin to
create a hole in the balloon's surface, the air
expands outward with so much energy that the
balloon explodes.

 Brake power recovery
 The body
 The Air Filter
 The chassis
 Electrical system

8. Engine:
Compressed air cars are powered by motors driven
by compressed air, which is stored in a tank at high pressure such as 30 MPa (4500 psi or 310
bars). Rather than driving engine pistons with an ignited fuel-air mixture, compressed air
cars use the expansion of compressed air, in a similar manner to the expansion of steam in a
steam engine.
Storage tank:
Carbon-fiber tanks safely hold air at a pressure
somewhere around 4500 psi, making them comparable to steel tanks. The cars are
designed to be filled up at a high-pressure pump.

10.  The first piston takes in ambient air and compresses it to
approximately 300 psi and 200*f in the compression
chamber during the first cycle of the engine
 When the piston pause, a small amount of compressed
air from the tanks is released into the expansion chamber
to create a low pressured, low temperature volume of
about 140psi
 Shortly before the valve to the exhaust cylinder is
opened, a high-speed shutter connects the compression
and expansion chambers. The sudden pressure and
temperature difference between the low chambers
creates pressure waves in the expansion chamber,
thereby producing work in the exhaust chamber that
drives the piston to power the engine

11.  The car engine runs on compressed air and incorporates the
three laws of thermodynamics
 The first law states that energy can neither be created nor
be destroyed
 The second law describes the disorder within substances
 The third law defines that only in crystals at 0o
k, there is
absolute disorder

12.  Runs on compressed air instead of gasoline.
 No pollution car.
 A two cylinder, compressed air engine, powers the car.
 The engine can run either on compressed air alone or act as an
internal combustion engine.
 Compressed air is stored in fiber or glass fiber tanks at a
pressure of 4351 pounds per square inch.
 The air is fed through an air injector to the engine and flows
into a small chamber, which expands the air.
 The air pushing down on the piston moves the crankshaft,
which gives the vehicle power.

13.  When the car is moving at speeds below 60kph,it
runs on air.
 At higher speeds, it runs on a fuel such as gasoline
diesel or natural gas
 Air tanks fixed to the underside of the vehicle can
hold about 79 gallons (300 litres) of air.
 This compressed air can fuel the car upto 200km at
a top speed of 96.5kph.When the tank nears empty
it can be refilled at the nearest air pump.
 The car motors require a small amount of oil about
0.8 litres worth that have to change just every
50,000km

14.  The engine has four stage pistons that are 8
compression and or expansion chambers.
They have two functions
 To compress ambient air
 To make successive expansions thereby approaching
isothermic expansion

21. Air Cars in the Marketplace :
 India 's Tata Motors will likely produce the first air car in the
marketplace in the next few years .
 Tata announced in August 2008 that they aren't quite ready to roll
out their air cars for mass production, Zero Pollution Motors still
plans to produce a similar vehicle in the United States. Known
collectively as the Flow AIR .
 The company, based in New Paltz, N.Y., says that it will start taking
reservations in mid-2009 for vehicle deliveries in 2010. The
company plans to roll out 10,000 air cars in the first year of
production
 MDI also recently unveiled the joystick-driven Air Pod, the newest addition
to its air car arsenal. Although the Air Pod generates a top speed of only 43
mph, it's also extremely light and generates zero emissions.

22. Companies working on air car
Production :
K'Airmobiles -- French company K'Air Energy has built
prototypes of an air-fueled bicycle and light road vehicle
based on the K'air air compression engine
Air Car Factories SA -- This Spanish company has an air car
engine currently in development. The company's owner is
currently involved in a dispute with former employer MDI
over the rights to the technology

4 . Better comfort
5 . Less Maintenance
6 . Low Cost

25.  Less power is produced
 Air pumping stations are less in number
 Inorder to ignite compressor we need Electricity
 Compressor needs Gasoline to compress air

 On accidents compressed air is dangerous

28.  Air powered cars is a realization of latest
technology in automobile field.
 It eliminates the use of non-renewable fuels
like gasoline, diesel petrol etc, and Thereby
preventing pollution caused by millions of

 This could be the future of automobiles and
step to a healthier environment
