Abstract: This paper describes the working of compressed air engine which is regarded as the fourth most utility after electricity, natural gas and water. Compression, storage, and release of air are termed as compressed air technology (CAT)As we know that the pollution caused by combustion of fuel is polluting the environment. Compressed air engine basically replaces the combustion of fuel with compressed air technology. Here air is compressed in small volume and stored in container. Since the air is at high temperature, it contains some amount of energy. This energy can be used to do some useful work (such as displacing the piston). The piston transmits the energy to crank which in turn rotates the wheels. Many other advantages of compressed air engine are there such as it is less costly, simple mechanism, easy to maintenance, explosion free. It can also be used for doing various operations in industries such as drive for conveyors, fluid pumps for small displacement. 
Keywords: Efficiency of CAT, load testing, pneumatic piston, 5-way-2position, rotary compressor, solenoid valve.
Scope of the Article: Refrigeration and Air Conditioning
