Hyderabad: Good news for bikers who no longer have to worry over the rising fuel prices. Young minds in engineering colleges continue to engage themselves in search for the ideal alternative fuel for vehicles as part of their projects which will have a positive impact on the environment. Imagine running your motorcycle without burning fuel. Imagine spending just a few rupees for travelling a hundred kilometres. Imagine a bike that emits just pure air as exhaust. These are indeed no imaginations, but thoughts crafted into reality.

The latest is an experimental model of a two-wheeler that uses compressed-air as fuel, developed by a team of final year mechanical engineering students of Brindavan Institute of Technology and Science, Kurnool, Andhra Pradesh. The team is headed by Ranganath along with Md Naveed Iqbal, Shaik Irfan and Yogi under the guidance of Somanna, Associate Professor in the Department of Mechanical Engineering. They have modified a motor cycle to run on compressed air, which means the bike uses only compressed air and doesn’t need petrol or diesel.

AERIS, the air bike, is a 135cc, 4-stroke petrol engine converted into air engine with a few modifications in suction stroke and compression stroke. As petrol prices are on the rise and the fossil fuel reserves are fast depleting, the students’ of Brindavan Institute of Technology and Science guided by Prof Somanna had come up with this innovative idea of using compressed air for running the bike. These bikes do not leave any carbon footprints and they are environment friendly due to their zero carbon-dioxide emission.

The team had a problem of refuelling the storage tank regularly and had overcome this problem by generating some amount of compressed air in the engine cylinder itself which did not appear in the prior inventions. An impact wrench gun has been used and the speed of the bike is regulated by a suitable mechanism. Compressed air is able to power the engine to speeds of up to 6000 rpm.

Designing a compact but high-capacity air tank to store sufficient ‘fuel’ for long rides is a major challenge to be addressed. The team is hopeful of coming with a suitable design soon. The air bike will drastically reduce running costs and will have zero emissions. The present air bike is still in the budding stage and further R&D would bring this bike on par with an ordinary petrol bike. Large scale production of air-powered motorcycles can benefit bikers economically.
