The document summarizes a seminar presentation on a compressed air car. It describes the key components of the vehicle, including compressed air tanks that store air at 300 bars of pressure, a fiber body, air filters to remove impurities from compressed air, and an aluminum chassis. The presentation explains that the car runs on compressed air stored in the tanks instead of gasoline, with two pistons that compress and expand air to power the engine. It concludes that compressed air cars could help reduce pollution by eliminating the use of non-renewable fuels.

COMPRESSED AIR CAR

2. INTRODUCTION
 Compressed Air Car- Powered by compressed Air Engine.
 It has Emission Free Piston, Engine uses Compressed Air as Fuel.
 Gasoline- Main source of Fuel, Very Expensive and Impractical
(Environmental Standpoint), Non- Renewable resource, it will
eventually run out.
 So one possible alternative is the compressed air car.
 Compressed Air Cars runs on Compressed Air instead of Gasoline.
 It powered by two cylinder compressed engine.

3. VEHICLE PARTS
COMPRESSED AIR TANK
 It localized Underneath the Vehicle.
 This Compressed Air Storage System is Safe to Risk of Explosion.
 It hold 90 cubic meters of air, compressed to 300 bars.
 the same tanks used to carry the liquid gas used by buses for
public transport.
 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.

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

5. 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.

6. 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.
 Aluminium allows quick assembly.
 And More secure join than Welding.
 This System helps to reduce Manufacture Time.

7. 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.

8. BASIC PRINCIPLE
The pistons work in two stages, intermediate stage of compression
and expansion.
Engine has two functions:
To compress ambient air.
To make successive expansions thereby power produced.
Detailed view

9. 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.
 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.

10. 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.

11. 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.

12. CONCLUSION
 Air powered cars is a Realization of latest technology in
automobile field.
 It eliminates the use of Non-Renewable fuels.
 It Prevents Pollution caused by Millions of Automobiles all
over the world.
 This could be the future of automobiles and step to a
Healthier Environment.
