Abstract:

      The Air Driven Engine is an eco-friendly engine which operates with compressed air. An Air

Driven Engine uses the expansion of compressed air to drive the pistons of an engine An Air

Driven Engine is a pneumatic actuator that creates useful work by expanding compressed

air. There is no mixing of fuel with air as there is no combustion.

     An Air Driven Engine makes use of Compressed Air Technology for its operation The

Compressed Air Technology is quite simple. If we compress normal air into a cylinder the air

would hold some energy within it. This energy can be utilized for useful purposes. When this

compressed air expands, the energy is released to do work. So this energy in compressed air

can also be utilized to displace a piston
