The air powered vehicle is a compressed air vehicle that uses compressed air for propulsion. It is an eco-friendly vehicle, which uses air as a fuel and works on the principle of Compressed Air Technology (CAT). These vehicles utilizes the expansion of compressed air to drive the pistons of an engine. The engine employed in an air powered vehicle is called an air driven engine, which is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air; subsequently, there is no combustion in an air powered vehicle. Implementation of stringent norms regarding carbon emissions by global regulatory bodies is a major factor that is estimated to drive the air powered vehicle market during the forecast period. Air powered vehicle is an answer to environmental degradation and energy shortages. It makes the vehicle more efficient and economical, as compared to fuel vehicles. All kinds of conventional sources of fuel are on the verge of exhaustion, ...
