Kinetic energy recovery system (KERS) is a technology used in formula-1 cars for recovering the energy lost in braking of the car and thus providing boost to the vehicle motion. Same concept i.e. regenerative braking can be applied in bicycle which uses a flywheel which will be mounted between the frames of the bicycle, the flywheel can store the braking energy by rotating and this energy can be given back to the system which will reduce the pedaling power required to drive the bicycle. This Flywheel Energy Storage (FES) system uses flywheel with suitable clutch mechanism along with sprocket and chains. Further this project concludes about efficiency and pedaling power in flywheel bicycle.

As we all know very well that vehicles run on petrol diesel CNG and LPG. This all fuels are the by-product of fossil fuel. As the number of vehicles increasing the use of fossil fuels are also increasing due to there the shortage of this fuel are seen in market and due to that the cost of that fuel is also increasing. Another disadvantage is that that after combustions of this fuel harmful gases are produce which cause air pollution. So we are going to introduce a hybrid two wheeler vehicle which will work on both fuel and electric power. In this we are going to attach motor directly with the gear box.

Abstract— “ENERGY NEITHER BE CREATED NOR BE DESTROYED BUT IT TRANSFORMS FROM ONE FORM TO OTHER.” In this transformation it may convert to either one form or different depending upon the forces acting, properties, type of materials and time etc.in many industrial applications this converted form of energy is also utilized to improve plant efficiency but major problem arises in recovery of this transformed energy. In automotive industry maximum amount of energy is wasted during braking. This problem is solved by the introduction of regenerative braking. Kinetic energy recovery system is a kind of regenerative braking system which has different approaches to store and reuse the lost energy. This paper mainly highlights the different ways of recovering energy using flywheel, super capacitors, batteries, hydraulic, hydroelectric actuators and influence of weight parameters for maximum performance of vehicle

With growing oil prices and escalating environment worries, cleaner and supportable energy solutions are demanded. Present transportation contributes large amount of energy consumption and emission of pollutants. We mostly use the vehicles like bike, moped bike, car etc. due to this the air pollution also get increased. Due to pollution the diseases are also increased. The petroleum products such as petrol and diesel are non-renewable sources. It gets exhausted in future, so to prevent environment from pollution and to save fuels like petrol and diesel the hybrid are introduced. Any vehicle is a hybrid, when it combines two or more source of power. Hybrid electric vehicles are admired because of their ability to achieve related performance to a standard automobile while prominently improving fuel efficiency and tailpipe emissions. In this paper, hybrid vehicle technology has been fabricate, with Power split configuration having internal combustion engine and battery as the secondary running source. In this project we make a hybrid bike which runs in two mode. Petrol mode:-The engine converts fossil fuel from the fuel tank into mechanical power. In this project first the bike will run with the help of petrol and the battery will charge with the help of alternator and generator. Electric mode:-In this mode the electric machine converts electric energy from an electric energy storage system such as battery into mechanical power. After that supply of petrol will cut, Now bike will run with the help of battery which is charged previously with the help of alternator

A „hybrid electric two wheeler' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. It has great advantages over the previously used gasoline engine that drives the power from gasoline only. It also is a major source of air pollution. The objective is to design and fabricate a two wheeler hybrid electric vehicle powered by both battery and gasoline. The combination of both the power makes the vehicle dynamic in nature. It provides its owner with advantages in fuel economy and environmental impact over conventional automobiles. Hybrid electric vehicles combine an electric motor, battery and power system with an internal combustion engine to achieve better fuel economy and reduce toxic emissions. In HEV, the battery alone provides power for low-speed driving conditions where internal combustion engines are least efficient. In accelerating, long highways, or hill cl...

In this paper, we are concerning about the growing demand of energy all over the world, which motivate us to switchover renewable resource of energy. There are many different ways by which we can save energy in different sectors. Our main focus is on automobile sector where we are converting old petroleum bike to electric bike. In these electric bikes we use Hub motor instead of combustion engine as there is less pollution, low maintenance cost, reduces noise. These bikes utilize chemical energy stored in the rechargeable battery packs. This paper deals with the design and development of electric bike which make use of electric energy as primary source. There is a distribution for charging the battery emitting it from the main system.

https://www.ijert.org/Design-and-Analysis-of-Parallel-Hybrid-Two-Wheeler https://www.ijert.org/research/Design-and-Analysis-of-Parallel-Hybrid-Two-Wheeler-IJERTCONV7IS06039.pdf The project work deals with the design and analysis of parallel hybrid two wheelers. The term "hybrid" denotes the vehicle using more than one power source. Today, the world is facing problems due to depletion of fossil fuels and the emission problems of two wheelers. The goal of the hybrid vehicle development is to combine different drive components, such as batteries and SI engines. To overcome the emission problems of two-wheeler, the hybrid concept is introduced in two wheelers which is running successfully in four wheelers. The gasoline powered SI engine is combined with the electric motor. The front wheel is driven by electric motor and the rear wheel of the vehicle is powered by IC engine. Initially, the vehicle is run on electric motor purely powered by battery up to the speed of 30kmph in the city covering the maximum range of 53km. If the battery is drained, then the vehicle switches over to the IC engine to reach the destination. When the vehicle reaches the highway, then it operates on hybrid mode, i.e., the spark ignition engine is used to run the IC engine for fast and smooth driving. It is noted that the vehicle can be operated in either battery or IC engine mode. And also during grading the vehicle can be driven by both modes to get the sufficient torque. A sealed lead acid battery of 48volt, 18amps and a brushless DC hub motor have been selected for the electrical drive mode.. A hybrid vehicle uses more than one propulsion systems to provide power for driving the vehicle. The most familiar type of hybrid vehicle is the gasoline-electric hybrid vehicles, which uses gasoline and electric batteries to power the internal combustion engine and electric motor respectively. Integrated Motor Assist (commonly abbreviated as IMA) is Honda's hybrid car technology, introduced in 1999 on the INSIGHT. It uses both gasoline engine and a thin, compact permanent magnet electric motor/generator mounted between the engine and transmission to act as a starter motor, engine balancer, and assist traction motor. The theory behind IMA is to use Regenerative Braking to recapture some of the energy lost through deceleration, and reuse that energy later on to help accelerates the vehicle. They also have a conventional starter as a backup, making it the only production hybrid system which can operate with its high voltage electric system disabled, using only its ICE like a traditional vehicle. For developing a hybrid electric two-wheeler the electric motor is a key component and the use of a high starting torque motor with good speed range is essential for an efficient hybrid concept. The size of the motor has to be smaller for space savings. For an entry level vehicle of interest, a performance equivalent of nearly a 100cc motorcycle suits the need. As it is necessary for any modern vehicle to have some flexibility in usage it should be capable of long highway hauls as well as challenging city driving conditions which can be fulfilled by having separate modes of operation for different terrains and different conditions. An improvement in acceleration of the vehicle is one thing that can be achieved with a hybrid vehicle with good starting torque and it helps a lot in city traffic conditions. A detailed control strategy has to be developed for fulfilling these conditions. An advanced power transmission system strategy is a key factor in the development of a vehicle combining more than one powertrains. It all depends on the hybrid transmission system that how fast and how efficient both the powertrains can be either combined or isolated to deal with different driving requirements. Cost consideration is another important aspect. Using low cost manufacturing techniques wherever possible, making some trade-offs to the desired parameters, a well-planned cost effective designing etc. can be considered to achieve this. The design can then consider using conventional battery and conventional metal parts to be made use of for cost savings, though the same might result in a lower life cycle of the storage system. Procedure for transmission and control system design can affect the cost factor and time factor. The ideas like parallel hybrid architecture can be thought of if there's a correct methodology for that. Since hybrid vehicles usually have more no: of components and complex construction, emphasis on reliability and safety is necessary. The complex electrical and electronics in HEVs shall be carefully designed for functional safety. 1.2. Formulation of control strategy The integration of conventional vehicle components with electric propulsion components results in a vast number of potential hybrid electric configurations. The series hybrid electric configuration is an interesting solution for driving in urban areas with passenger cars, light duty

It is used to recover energy lost during breaking as well as to transform kinetic energy loss into kinetic energy gain. When riding a bicycle, braking consumes a significant amount of energy. We employed a mechanical kinetic energy recovery system with a flywheel to store energy that is ordinarily lost while braking and then reuse it to assist the rider in driving after a rest. The engagement-disengagement mechanism transfers kinetic energy from the back wheel to the flywheel through chain drive. During the pause, the flywheel stores the available energy and powers the rear wheel back up. The recovery speed of KERS is extremely slow in theory and significantly worse in practice. The weight of the flywheel can be increased to increase the recovery speed and hence efficiency. However, putting too much weight on bike will prevent you from cycling normally. The ideal flywheel weight is between 5 and 8 kg. We will use the Fusion 360 software to create the bicycle, and then we will utilize Ansys to simulate the model. We'll also determine the speed ratio by determining the speed of a bicycle with and without a flywheel

Hybrid-electric vehicle (HEV) combines the benefits of petrol engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power and reduced emission leads to green environment. In recent days, availability of fuel source is depleting day by day and due to more consumption of fuel, the environmental pollution is increasing. In order to overcome that issue we have remodelled a two wheele r as a hybrid two wheeler which means the vehicle can use electric power additionally for its working. In hybrid two-wheeler, there are three modes such as fuel mode, electric mode and dual mode. Initially, vehicle runs in fuel mode and after saving energy from this using dynamo, electric mode starts and the motor is used to run the vehicle and the speed of the vehicle is controlled by using rheostat; and in dual mode, both engine and motor are used in case of high load carrying and quick travel.
