A group of five Mechanical Engineering students at

Agnel Institute of Technology and Design, Assagao have devised a bike in their final year project, aiming at a more efficient and a greener tomorrow. The team comprises Vincente Mathias Cabral, Shorwin Pauluis De Souza, Nathaniel Duarte E Bragança, Phlegon Vincy Fernandes and Anish Prabhu Chandelkar. Their project is known as the ‘Design of Vehicle Range Extender’, having utilised an electric brushless hub motor that is used to drive the bike on its electric mode. It is powered by a pack of Lead-acid batteries, whereas the rear wheel is the Normal IC (Petrol Drive). Since it is a Parallel Hybrid, both modes are independently operated and therefore for rider convenience and ease, the desired mode of riding can be selected depending on the whims and fancies of the rider.

This project stands out, in the aspect that it allows the rider to select the desired drive mode, instead of the bike automatically switching over (ECU controlled) the modes depending on the speed variation. Reduced air emissions and increased range is the key objective of this project. The focus is to conserve fuel, increase the range and reduce environmental emissions especially in locations like the city, at idling conditions and at frequent start-stop (traffic signals). It is noise free as well, due to reduced number of moving parts which include the electric drive. In addition to the normal range obtained by the petrol drive, a longer range coupled with a fully charged electric mode is achieved.

The journey began in July 2018, when they formed their project group of five members. The total active duration of their project of approximately six months as the initial period was utilised for basic research. Initially, they faced a lot of hardships, troubles and failures, which made it nerve-racking for them but eventually, they gained courage and redirected their plan and ideas. As the need of the hour is to save the environment by reducing pollution in various forms possible, they decided that they could contribute to this purpose by making a bike that would not compromise on the performance, give an improvised efficiency and primarily reduce the exhaust emissions. As the project was of their choice and interest, they were determined and took it up with enthusiasm. Things got challenging as they were keen on getting them time bound. They adopted a working strategy in which all of the team members got together on the job for a specific task with a time limit.

For them, the experience of working on this project was in fact the best part of engineering as they could creatively implement their thoughts and apply their knowledge as compared to the boredom in the monotonous learning process throughout the four years. They believe that the project chosen by the students in their individual groups should be taken up by each member with maximum enthusiasm as it could be the foundation of their career. The objective should be to innovate and implement ideas to benefit mankind simultaneously having minimal ill effects on the environment.

The team members are grateful to their parents and their guide Prof Amol Patil for his guidance. They also thanked their Principal Dr V Mariappan for being the driving force throughout, in accomplishment of their goal.

Their external examiner N Dessai also appreciated their project, stating that such projects should be recognised and encouraged by the government, to be taken up, by aiding in providing a platform on a commercial scale, which will earn revenue to the state on implementation.
