The environmental pollution in the metropolitan cities is increasing rapidly mostly because of the increased number of fossil fuel powered vehicles. Many alternative options are now being studied throughout the world. One of the alternative solutions can be a compressed air powered engine. The main advantage of this engine is that no hydrocarbon fuel is required which means no combustion process is taking place. In this work, a pneumatic cylinder activation is used as a linear source and with the help of crankshaft, the rotational movement is obtained. The flow of air inside the pneumatic cylinder is controlled by means of the solenoid valve which is actuated periodically by an electronic control unit. As we completely changed the usage of existing conventional engine to a simplified air powered one, this new technology is easy to adapt. Another benefit is that it uses air as fuel which is available abundantly in the atmosphere. With the use of these technological advances this small concept of using compressed-air could really make a difference. The use of pneumatics could help save the fuel costs to a great extent. This concept mainly focuses on the non-usage of the conventional style fuels that have been used for centuries in automobiles and as a result, there has been a tremendous growth in the pollution sector especially in the busiest countries. Also, the anti-pollution measures taken by humans are very less so that means we are the verge of global warming which inflicts a great deal of disaster on a large scale human as well as other living population. Future modifications could render some major design revolutions that could let us use this in many sectors.
