ABSTRACT:

Today the world is facing a very serious problem due to the scarcity of fossil fuels. Due to increase in the prices of the fossil fuels there is a need for an alternate form of energy. This made us to think towards the technology of using compressed air as an alternate fuel in the rapidly developing automobile field. In our project we have designed a compressed air car which is reliable and economical in the current scenario. The compressed air car is an alternative fuel car that uses a motor powered by compressed air. The idea of using compressed air as a fuel is not new. There have been prototypes cars since the 1920s, but here we have used air motor as a prime mover which is more efficient than the air powered engines used in the already existing prototypes. Furthermore, additional attention was gained because of its possible environmental advantages over fossil fuel as it is emission free at the tail pipe. And also in contrast to the issues of damage and danger involved in high-impact crashes, air, on its own, is non-flammable. All over the advantages cannot be limited and they are further discussed in this paper.

INTRODUCTION:

Here in the pneumatic systems we use pressurized gases to transmit and control power. As the name implies pneumatic systems typically use air (rather than some gas) as the fluid medium, because air is a safe, low cost, and readily available fluid. It is particularly safe in environments where an electrical spark could ignite leaks from system components. Here the compressed air is stored in the carbon fiber tanks which have passed safety standards holding gas at 10,000 lbf/in² (70 MPa). The compressed air in tank contains various contaminants. This air is first passed through the filter in the FRL unit in order to remove the contaminants, which might harm the closely fitting parts of the pneumatic components such as valves and cylinders. Then the air passes through the pressure regulator, which reduces the pressure to the desired level for our application. Because air is not a good lubricant, pneumatic systems require a lubricator to inject a very fine mist of oil into the air discharging from the pressure regulator.
