Air-Powered Cars

Abstract

This paper is reporting an experimental investigation of an engine driven by compressed air. The compressed-air engine is modified from a four-stroke working engine to two-stroke working engine (power and exhaust) by modification of cam-gear system. The project was successfully manufactured and tested. Experimental results were carried out on this modified engine to find out its performance characteristics like brake power, mechanical efficiency, indicated power, torque, etc. It should be noted that pressure higher than that currently employed can result in increased engine performance in terms of output power, torque and speed. The main advantage of this engine is that no hydrocarbon fuel is required, which means no combustion process is taking place. Thus the compressed-air vehicle will play an important role in reducing air pollution. Another benefit is that it uses air as fuel which is available abundantly in atmosphere. This study presents that atmospheric air in can be used in vehicles as the main or alternative source of power system.
