A Comparative Experimental Study of Compressed Air Engine in Existing Single Cylinder 2 Stroke and 4 Stroke Engines

Keeping in view the internal-combustion engines pollute the environment seriously, the climate change, the dependence on petroleum reserves as the primary energy source, and volatile fuel prices, it is necessary to discover possible opportunities in unconventional alternative-fuel technologies. One of the choices available is the Compressed Air Vehicle (CAV), or air car, which are offer environmental and economic benefits like zero emissions. In this paper, a physical model of compressed air engines (CAEs) is established from existing 4 stroke and 2 stroke petrol engine. To obtain performance on the CAEs, a setup is prepared with dynamometer. The output torque, break power and fuel consumption are obtained through experimental study. The results show that CAE has a good economic performance at constant pressure 6 kg/cm2 provide max 0.886 kW power output with varying load 0.5 kg to 2.5 kg for modified air engine from existing 4 stroke engine and 2 stroke engine. This research can be referred to in the optimization of air-powered engine.
