DESIGNING AND FABRICATION OF POLLUTION FREE CAR

It was hard to believe that the compressed air can be used to drive vehicles. However it is being popular and has been used to catch the attention of researchers worldwide having zero emissions and is ideal for city driving conditions. The air car currently being designed, developed, manufactured and then powered by an air engine, specifically it was for the savings of fossil fuel and air pollution. Although it seemed to be an environmental-friendly solution, it must be considered that it is good for wheel drive in specific range. As the world is hard pressed with the energy and fuel crises, compounded by pollution of all kinds, any technology that brought out the solution to this problem was a gift. In one of such new technologies, was the development of a new engine called as “Compressed Air Engine”, which did not require any of the known fuels like petrol, diesel, CNG, LPG, hydrogen etc. this worked using only compressed air and it replaced all types of known fuels and also permanently solved the problem of pollution, since its exhaust was clean and cool air. Experimental analysis were carried out on this modified engine to find out its performance characteristics like brake power, mechanical efficiency, overall efficiency, air to air ratio and cost analysis etc. The basic principle involved in this project was that the compressed air was capable enough to provide sufficient thrust which in turn can propel the car instead of using fuels to get the thrust in the engines. Weight of the car is 80kg and it runs on 60km/h and its efficiency is 14-18%.
