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. KEYWORDS: Prototype, Compressed Air, Experiment, Performance I. INTRODUCTION At first glance the idea of running an engine on air seems to be too good to be true. Actually, if we can make use of air as an aid for running an engine it is a fantastic idea. As we all know, air is all around us, it never runs out, it is non- polluting and it is free.An Air Driven Engine makes use of Compressed Air Technology for its operation. Compressed Air Technology is now widely preferred for research by different industries for developing different drives for different purposes. 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. This is the basic working principle of the Air Driven Engine. It uses the expansion of compressed air to drive the pistons of the engine. So an Air Driven Engine is basically a pneumatic actuator that creates useful work by expanding compressed air. This work provided by the air is utilized to supply power to the crankshaft of the engine.In the case of an Air Driven Engine, there is no combustion taking place within the engine. So it is non-polluting and less dangerous. It requires lighter metal only since it does not have to withstand elevated temperatures.As there is no combustion taking place, there is no need for mixing fuel and air. Here compressed air is the fuel and it is directly fed into the piston cylinder arrangement. It simply expands inside the cylinder and does useful work on the piston. This work done on the piston provides sufficient power to the crankshaft. II. HISTORY Compressed air has been used since the 19th century to power mine locomotives and trams in cities such as Paris (via a central, city-level, compressed air energy distribution system), and was previously the basis of naval torpedo propulsion. In 1863, Jules Verne wrote a novel called Paris in the 20th Century about a world of glass skyscrapers, high- speed trains, and air-powered automobiles. In 1903, the Liquid Air Company located in London England manufactured a number of compressed air and liquefied air cars. The major problem with these cars and all compressed air cars is the lack of torque produced by theengines, and the cost of compressing the air.

COMPRESSED AIR TECHNOLOGY Air can be compressed into small volumes and can be stored in suitable containers at high pressures. Such air compressed into containers is associated with an amount of energy. When the stored compressed air is released freely it expands thereby releasing the energy associated with it. This energy released can be utilized to provide useful work.The compression, storage and release of the air together are termed as the Compressed Air Technology. This technology has been utilized in different pneumatic systems. This technology has been undergoing several years of research to improve its applications. Compressed air is regarded as the fourth utility, after electricity, natural gas, and water. Compressed air can be used in or for: ฀ Pneumatics, the use of pressurized gases to do work. ฀ Vehicular transportation using a compressed air vehicle ฀ Scuba diving ฀ To inflate buoyancy devices ฀ Cooling using a vortex tube ฀ Gas dusters for cleaning electronic components that cannot be cleaned with water. ฀ Air brake (rail) systems ฀ Air brake (road vehicle) systems ฀ starting of diesel engines (an alternative to electric starting) ฀ Compressed air breathers (such as Suisse Air) ฀ Pneumatic air guns ฀ Pneumatic screwdrivers 2. SOLENOID VALVE A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid coil. Solenoid valves may have two or more ports: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports.
