Engineering students convert moped into a race bike !

Bangalore: - It is unimaginable, but innovative brains have done it. A group of young talents from Bangalore have converted a moped into a race vehicle that can match the world standards.

Moped races are very popular in European and Western countries but are not very common in India. The young minds of NITTE Bangalore lead by Rohan R Baindoor developed one of the fastest vehicles in this category. The race modified bike has an engine capacity of 142 cc, weighs 60 kg and has an acceleration of 2.8 sec.The magnificent idea of converting a moped into a race vehicle was instigated by the fact that they were inaccessible to sufficient data and requirements and decided to generate their own design based on experimentations.

Their work was initiated with the purchase of an engine. The engine was selected from various moped/scooters. The main criteria behind the selection were to get maximum power output. Suzuki Access (125cc) engine was found to be the best suitable engine for their project. “At the beginning the engine was overhauled and the necessary alterations were made by cylinder boring to increase the engine displacement. Also, the cylinder head porting was done for smooth and customized fuel flow which was previously absent in the engine,” Rohan said.High performing spark plugs, CDI (Capacitor Discharge Ignition) coil units and other aftermarket products were incorporated to provide excellent current supply to burn high octane fuel. Carburetor rejecting was done to have optimum fuel flow. Vehicle clutch, camshaft were also subjected to minor alterations to meet their requirements.“The chassis was the most challenging task that was to be designed so that it had to be lightweight and provide good aerodynamics,” he said. The group decided to choose aluminum for the entire chassis design as it had desirable properties compared to normally used mild steel. The square aluminum beam was cut into required dimensions and it was precision TIG welded which was a very cumbersome job. Gazettes, which were laser cut, are provided at six vital locations on the chassis to obtain good strength. Normally, for mopeds the rake angle is 28°, increased this angle by 7° to have more stability.The vehicle parts included various aftermarket products like aluminum alloy wheels, customized fuel tank, front forks, and handle bars etc. The outcome was the integration of all the above mentioned activities which resulted in an intended racing moped. Rohan said that their vehicle would commensurate with the standards considered. Therefore the moped was very close to European race moped standards. The project involved a lot of engineering and technological skills and the group also gained real time exposure to practical environment.

Engineering students develop 110 km/liter diesel bike !

Have you ever imagined of a two-wheeler that runs on a diesel engine? Four engineering students from Bangalore have developed a diesel bike that gives a mileage of 110km/liter - a challenging task accomplished by the innovative brains.

A magnificent idea that can be of a great help to the common man who struggles with the never-ending fuel price hikes, the young brains from the at the M S Ramaiah Institute of Technology took the challenge of developing a two wheeler diesel engine with automatic gear and automatic clutch and have successfully carried out the project.

Guided by their project guide Dr. S V Prakash, four mechanical engineering students namely Naveen V V, Tony Paul, Nadeem Anwar and Sanjay Bhushan decided develop a diesel-run two-wheeler as our final year project. Fitting a Bullet engine to Kinetic Blaze, they had to do a lot of alterations. While spending four months on the project with various workshops in Bangalore and Coimbatore, they reduced 325cc engine to 200cc, flywheel weight reduced to 7kg and power reduced to 3.5 hp from 6.5 hp apart from many other alteration works.

"We have spent almost 72 thousand on the production of this prototype and with mass production, the cost would be around 55 to 60 thousand," said Nadeem Anwar, a member of the team.

The highlight of the innovative work is that it gives a mileage of 110km/liter and it reduces travel expense to a great degree as diesel engine runs at 40 paise per km and petrol engine runs at 1.70 per km. The vehicle offers a smooth ride with automatic gear and clutches and is less polluting compared with other diesel-engine vehicles. In addition, the life of a diesel engine is generally about twice as long as that of a petrol engine.

Dr. S V Prakash, the project guide who has been a great help to the young students to materialize their dream project, said India's largest engineering and construction conglomerate 'Kirloskar Group' has shown interest in the technology and has offered to further assistance to the project.
