Abstract:- There are so many vehicles that came to influence in the existing world. Their operating systems are based on usual fossil fuels system. At the present sense the fossil fuel can exceed only for a certain period after that we have to go for a change to other methods. Thus we have made an attempt to design and fabricate an ultimate system (solar cycle) which would produce cheaper and effective result than the existing system. This will be very useful needs of the world. An attempt is made in the fabrication of solar powered system for a two-wheeler. The drive system of the normal cycle is not altered. This system is two in one system. The cycle is operated either by pedaling manually battery and motor driving mechanism. Index Term: Dynamo, Throttle, Pedaling, Battery, Sprocket I. Introduction:- All vehicles that are in the market cause pollution and the fuel cost is also increasing day by day. In order to compensate the fluctuating fuel cost and reducing the pollution a good remedy is needed i.e. our transporting system. Due to ignition of hydrocarbon fuels, in the vehicle, sometime difficulties such as wear and tear may be high and more attention is needed for proper maintenance.

  • Powering the Electric Vehicle with a Dynamo Using Wind Energy
    JOURNAL OF CRITICAL REVIEWS ISSN- 2394-5125 VOL 7, ISSUE 19, 2020 POWERING THE ELECTRIC VEHICLE WITH A DYNAMO USING WIND ENERGY Mr. Kamalpreet Singh1, Dr. Harbinder Singh2, Dr. Harpal Singh3, Dr. Mohit Srivastava4 1Computer Science Engineering, Chandigarh Engineering College, Landran, Mohali, India. 2,3,4Electronics and Communication Engineering Department, Chandigarh Engineering College, Landran, Mohali, India. E-mail: [email protected], [email protected], [email protected], [email protected] Received: 14 March 2020 Revised and Accepted: 8 July 2020 ABSTRACT: The main objective of this paper is to represent a method for powering the electric car with a dynamo using wind energy. We want to solve the major disadvantage faced by an electric vehicle that is the discharge of the battery in case there is no power source. In case there is no power station nearby then electric vehicle can’t reach its desired destination. To solve this problem dynamo can be used. Dynamo is a device that converts mechanical energy into electric energy. Hence by using this property of a dynamo, this problem can be solved. The description of this technique is placing a dynamo behind the radiator and fan in front of the radiator. A hole is created at the centre of the radiator to connect the dynamo with the fan using a shaft. Due to locomotion of a car fan will rotate and current will be produced with the help of a dynamo. This technique has one more benefit that is efficiency of heat dissipation from the radiator will increase with the help of a fan.

  • Monitoring Internal Combustion Engines by Neural Network Based Virtual Sensing
    Monitoring Internal Combustion Engines by Neural Network Based Virtual Sensing R.J.Howlett, M.M.de Zoysa, S.D.Walters Transfrontier Centre for Automotive Research (TCAR), Engineering Research Centre, University of Brighton, Brighton, U.K. Email [email protected] Abstract Over the past two decades the manufacturers of internal-combustion engines that are used in motor vehicles have been very successful in reducing the harmful side-effects of their products on the environment. However, they are under ever-increasing pressure to achieve further reductions in the quantities of polluting gases emitted by the engine, and a decrease in the amount of fuel consumed per kilometre. At the same time, vehicle characteristics that are desirable to the driver must not be compromised. Satisfying these diverse requirements requires precise engine control and comprehensive monitoring of the operational parameters of the power unit. Engines are highly price- sensitive, and it is desirable to achieve the increased level of measurement that is required for enhanced control without additional sensory devices. Thus, the indirect estimation of quantities of interest using virtual-sensor techniques, without direct measurement using dedicated sensors, is a research area with considerable potential. Intelligent-systems techniques, such as neural-networks, are attractive for application in this area because of their capabilities in pattern- recognition, signal analysis and interpretation. For this reason, the use of neural-networks in the monitoring and control of motor-vehicle engines is an area of research which is receiving increasing attention from both the academic and commercial research communities. A virtual-sensor technique, the Virtual Lambda Sensor, is described here which uses a neural-network for the estimation of air-fuel ratio in the engine.
