The document discusses the future of air powered automobiles. It describes how air cars work as an alternative to gasoline vehicles, which are facing fuel crises and causing air pollution. The key components of an air car include a compressed air tank, air engine that uses compressed air instead of gasoline, and a brake power recovery system. Air cars have advantages like being pollution free and having a simple, lightweight engine, though they have less speed and require refueling every 3-4 hours. The conclusion states that air cars eliminate non-renewable fuels and prevent pollution, paving the way for a healthier environment.

2. THE AIR CARS
THE FUTURE OF
AUTOMOBILES

3. REASON FOR THE ARRIVAL OF AN AIR POWERED VEHICLE
• Today we are facing fuel crisis and also air pollution ;
• Now a days we are using gasoline as a major fuel
which is going on expensive also it is non-renewable ;
• So an alternate for gasoline has to be adopted ,
C0MRESSED AIR serves this purpose .

4. THE AIR CAR
• The Air Powered Car is
powered by air engine
which uses COMPRESSED
AIR as fuel.
• The air powered car is
also called as a low
pollution or zero
pollution cars.

5. MAJOR PARTS OF AN AIR CAR
• Chassis
• Body
• Compressed air tank
• Engine
• Break power recovery
• Air filter

6. CHASSIS OF AN AIR
CAR
• Highly resistant and light
chassis
• Made of aluminium
• Aluminium rods are glued
not welded
• Aluminium rods enables
more shock resistant
chassis than other regular
chassis

7. BODY
• It is made up of FIBER and INJECTED FOAM.
• It does not rust
• It does not cut like steel
• Light weight material that improves the
efficiency of the car

8. COMPRESSED AIR TANK
• It is the most important part of these cars • It is made of carbon fiber
• These tanks hold 90 cubic metres of air • It can be ruptured but can’t be
explode since there are no metals in them.

9. • Engine uses compressed air as a fuel
• It has normally two cylinder engines for
mid range cars.
• It runs normally like a gasoline engine but
there is a absence of combustion chamber.
ENGINE

10. BREAK POWER RECOVERY
• It is a pneumatic system which plays an important role in air
powered cars
• Brake power recovery means , the engine stops when the car is
stationary ( at traffic, junctions , railway crossings, etc.,.).
• It saves 13% of the power used.

11. AIR FILTER
• engine works with both air taken from the atmosphere and also from
compressor tank
• Before compression, the air must be filtered to get rid of any impurities
that could damage the engine.
• Carbon filters are used to eliminate dirt, dust, humidity and other
particles
• It is the first time that a car has produced minus pollution.
• The exhaust pipe on the cars produces clean air, which is cold on exit
(between -15º and 0º) and is harmless to human life.

12. WORKING
• First piston takes atmospheric air and
compresses it to approximately 300 psi in the
compression chamber
• Then a small amount of air from the tank is
released in to the expansion chamber at a low
pressure of 140 psi also at low temperature.
• A high speed shutter connects the
compression and expansion chambers.
• The sudden pressure and temperature
difference between the compression and
expansion chambers creates pressure waves in
the expansion chamber, thereby producing
work in the exhaust chamber that drives the
piston to power the engine.

13. •POLLUTON FREE
•LIGHT WEIGHT ENGINE
•SIMPLE IN
CONSTRUCITON
•LESS COST AND MORE
EFFECTIVE
LESS SPEED
RE FUELING AT EVER 3- 4
HOURS

DISADVANTAGES

15. CONCLUSION
• Air powered cars is a realization of latest
technology in automobile field.
• The air car is a clean,easy to drive,light weight
and high performance car.
• It eliminates the use of non-renewable fuels and
thereby preventing pollution and step to a
healthier environment.
• Tata Motors has signed an agreement with
Moteur Development International (MDI) of
France to develop cars that runs on compressed
air.
