An Experimental Investigation on Compressed Air Engine

Now a days, the serious environmental issues, such as greenhouse effect, ozone layer depletion and fog and haze, have drawn considerable attention. Burning of fossil fuels pollutes the environment seriously, and consume enormous non-renewable energy so Today the whole world is in search of alternative fuel. To avoid such environmental problems, renewable energy has been applied to automobiles. In this paper, an air-powered engine of a renewable energy vehicle is introduced. a physical model of compressed air engine (CAE) is established with modified came from existing 4 stroke petrol engine. . To obtain performance on the CAE, a setup is prepared with dynamometer. The output torque, break power and fuel consumption are obtained through experimental study. The results show that the prototype of CAE has a good economic performance at constant pressure 6 kg/cm2 provide max 0.779 kW power output with varying load 0.5 kg to 2.5 kg. This research can be referred to in the optimization of air-powered engine.
