Project Title

Hybrid Bike

Project Area of Specialization Mechatronics EngineeringProject Summary

Hybrid bike project is a project which is chosen keeping in veiw about the current situation of fuel prices and utilizing the energy from electricity This bike will use two energy resources that is thermal energy in internal combustion engine and electrical energy from battery to dc motor for motion of bike . it will work based on hybrid system. The input energy shift will be monitiored and shifted using a controller which is defined through programming on arduino board. Honda , Metro , Road prince , etc and many other bike manufacturers are using the japnese bike design so we are using the same design so that people will not feel hesitant in using it. This project will help shift the dyamics of petrol based Spark ignition engine towards the electric sourced energy effecient systems as encouraged by the Government of Pakistan and this Project will help in the shifting; Petrol to electric powered sources by giving the opportunity to consumers to see for themselves the difference between the two systems.The engines will not be wasted since they will be integerated with a battery system thereby creating a Hybrid system.

Project Objectives

To build a two wheeled hybrid bike based on electric motor powered by batteries and an SI engine. The SI engine wastes a lot of heat energy during braking of the vehicle so a hub motor will be installed in the rim of wheel to utilize the heat energy and convert it into voltage to charge the batteries which will then power the electric motor for drive using electrical energy. This process will ensure that wasted energy from the 4-stroke cycle of the engine is utilized and used again by conversion from one form to another using law of conservation of energy.

This process will reduce emission of harmful gases formed by combustion in the environment significantly since the motorbike will be working on SI engine and electric motors for drive. The system will use less fuel and emit less emission as compared to the conventional motorbike Thereby it will reduce pollution in the environment.

Hybrid bike will improve the mileage significantly because it will not be entirely dependent on a single source of power; Electric motor and SI engine. This will help reduce the cost of travelling on the bike because when the batteries are fully charged and electric motors have enough power to supply for driving needs the SI engine can be turned off. Electric motors and batteries by themselves do not provide enough power but that may change in the future as fuel cell technology advances but for existing technology a motorbike powered by External batteries and an SI engine will give enough power to drive under steady conditions. A smaller engine can be optimized using this system of Batteries and Hub motors such as that of a 70cc bike which has merely 7 Horse power therefore it will have diversity of application to different sizes of engines.

Project Implementation Method Methodology:

Research Overview:

The research work based on development of hybrid bike. Keeping in view the existing Japanese bike design in Pakistan, this project will be done by changing and modification according to automotive standards.  Hybrid bike will be a bike that can work on both gasoline engine (IC engine) as well as on electricity means it can change it power source whenever needed. To some extent it is the concept as per Toyota car company is using in its hybrid cars like Prius, Avalon Hybrid. It will work in such a way that when the allowed speed limits and battery backup will be crossed the electric power will shut down and the bike will be converted on gasoline engines.

Following is the simplest block diagram for our concept design.

Experimentation:

According to public survey, experiments will be conducted in real life conditions for the best possible outcome. The efficiency of simple gasoline engine is pre-known but of hybrid bike is not so after the selection of best suitable parameters such as load, speed limits, battery backup, etc it will be prone to daily life challenges for testing. Moreover testing of electrical components can be done in the labs of university as well as outside university.

Theoretical Studies:

The knowledge available about the gasoline engine and the electrical parts will be gathered for the guidance. Well known parameters that can hampered the performance will be taken into consideration from the books available on-line, the data available on internet and from the previous researches.

Results Calibration:

Estimated results will be compared with the bike already available in markets so that we can analyze that are we moving in the right direction and this technology will have a scope in future. The performance of hybrid bke will be compared with electric bikes and gasoline bikes.

Technical Details of Final Deliverable

A self start bike would be  integrated with a brushless dc motor and a battery to run that motor and a generator which will use the energy form the bike when is would be running on internal combustion engine to charge the batteries without external source. After a certain speed limit the arduino base circuit would assist the shifting of input energy source.
