The automotive industries are looking for many ways in order to reduce the weight of the vehicle. Also, light vehicles are better at handling and also efficiency of the vehicle is more. Heavy weighted vehicles as compared to light weighted vehicles produce a large amount of harmful gases like CO2 and SO2. There are many alternatives in order to reduce these harmful gases. One such alternative is using compressed air to power the vehicle. So, in this research work the main aim of the project is to design, fabricate and test a single seated vehicle that runs on an alternative source of energy, specifically compressed air. A pneumatic rotary engine having a maximum pressure of 7 bar is used in designing the above air compressed vehicle. In order to achieve speed of 30-40 Km/hr, two air cylinders are used in this design. From this study it can be concluded that using less dense and higher volume tank it is possible to increase the output velocity of the vehicle. The findings of this research can be used for further development of air compressed vehicle.
