“Compressed air cars” are cars with engines that use compressed air, instead of regular gas used in conventional fuel cars. The idea of such cars is greatly welcomed by people of the 21st century, when pollution caused by petrol and diesel is an extremely worrying factor.

  

Engine and Technology

The engine that is installed in a “compressed air car” uses compressed air which is stored in the car’s tank at a pressure as high as 4500 psi. The technology used by air car engines is totally different from the technology that is used in conventional fuel cars. They use the pressure generated by the expansion of compressed air to run their pistons. This results in ‘no pollution’, as air is the only product that is used by the engine to produce power, and the waste material is the air itself.

INTRODUCTION

We are confident that Compressed Air Technology (CAT) holds the key to the automobile's future. At the same time, though we are aware that no one type of vehicle can meet all society’s needs. That's why we are pushing ahead with research on a range of vehicle propulsion technologies.


COMPRESSED AIR TECHNOLOGY (CAT)
Compressed Air Technology (C.A.T.) uses compressed air as its energy source and requires no gasoline or batteries to drive the engine. C.A.T. is developed by Mr. Guy Negre to run engines with compressed air. Although the technology is new, the idea isn't completely unknown to Formula One Cars & those interested in engine technology. In fact, every Formula One engine starts with a shot of compressed-air as an Energy-Booster. Guy Negre has simply extended its potential by turning it into a single source of energy for running the engine.



WORKING OF C.A.T. ENGINES
In principle the technology is very similar to the internal combustion system in that compressed air is used to drive a piston in a barrel. The secret of the engine lies in the way it efficiently converts the energy stored in the tanks of compressed air.

Air Storage Tank/Fueling

As thought by engineers and designers, the storage tank would be made up of carbon fiber to reduce the car’s weight and prevent an explosion, in case of a direct collision. Carbon-fiber tanks are capable of containing air pressure up to 4500 psi, something the steel tanks are not capable of. For fueling the car tank with air, the compressor needs to be plugged into the car, which would use the air that is around to fill the compressed air tank.

This could be a slow process of fueling; at least until air cars are commonly used by people, after which high-end compressors would be available at gas stations that would fuel the car in no time at all.

Emission

The air-powered car would normally emit air, as it’s what it would solely use. But it would totally depend on the purity of air that is put into the air tank. If impure air is filled in the tank, same would be the level of impurity of the emission. The emission level would highly depend on the location and time of filling air in the tank.

ADVANTAGES
• Zero emission vehicle 
• No fossil fuel required.
• Operating cost 75% less as compare to the gasoline engines.
• Price is also less then half of the electric vehicles.


DISADVANTAGES

• It can’t give much higher speed.
• The recharging stations.

CONCLUSION
Nowadays the earth is facing the biggest problem of global warming. The major cause for this is the environmental pollution. Fossil fuel vehicles are the major contributors to this pollution. In order to irradiate this problem the solution is hybrid electrical vehicles but again they emit some pollutants, hence it is not a complete solution.
