Compressed Air Cars
“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 in Compressed Air Cars
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.
Air Storage Tank/Fueling in Compressed Air Cars
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 in Compressed Air Cars
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.
