Abstract This paper deals with the problems which emanates in front of society in developing electric vehicles. Aim of this paper is to prepare ways through which we can develop electric vehicle with efficiency (more than 60%). So that these electric vehicles can substitute I.C engine vehicles, which are main cause of environment pollution. To achieve that goal, various competitions are arranged in which one sitter kart develop to ease mechanical constraints and easily utilize innovations in kart. To develop kart various type of modelling and simulation were done on INVENTOR and ANSYS 14.0. Different type of test were also taken into account like Brake test, Speed test, Power test, Load test, and efficiency test. This paper also motivates student in developing vehicles so that they can excel their knowledge and assist in research of electric vehicles.

Abstract To increase the range of a Battery Electric Vehicle (BEV), a lot of ideas have been proposed. A prominent one among them is the Battery swapping methodology or Rapid Battery Interchange (RBI), where standardized batteries can easily be removed from the BEV and replaced with recharged batteries quickly. The feasibility of this methodology has been highly debated and contested. This paper studies the feasibility of a very popular distribution and maintenance network currently used for LPG distribution in India, to be applied to battery distribution used across different makes and models of BEVs. In India, 33.6 million households subscribe to LPG Cylinders for domestic cooking usage. These standard sized (14.2Kg) cylinders are refilled and redistributed via multiple public sector and private companies.

Abstract The performance of any automotive engine depends not only upon its core engine parts but also on the effectiveness of the sub-systems attached to the engine, like the intake, fuel, engine cooling and exhaust systems. The exhaust system being a critical system of any automotive vehicle plays a responsible role of improving the ride quality of the vehicle and fuel economy. The effective design of exhaust system is critical in order to ensure the required exhaust gas is exited from the engine and at the same time the noise is attenuated. In this paper a novel approach is developed in order to characterize the flow through the cold end exhaust system and reduce the pressure drop to achieve desired performance. The exhaust system attenuates the noise from the engine without deteriorating the engine performance by ensuring an optimum value of exhaust back pressure.

This recommended practice provides guidance on vehicle Cybersecurity and was created based off of, and expanded on from, existing practices which are being implemented or reported in industry, government and conference papers. The best practices are intended to be flexible, pragmatic, and adaptable in their further application to the vehicle industry as well as to other cyber-physical vehicle systems (e.g., commercial and military vehicles, trucks, busses). Other proprietary Cybersecurity development processes and standards may have been established to support a specific manufacturer’s development processes, and may not be comprehensively represented in this document, however, information contained in this document may help refine existing in-house processes, methods, etc. This recommended practice establishes a set of high-level guiding principles for Cybersecurity as it relates to cyber-physical vehicle systems.

The ISO GPS Ultimate Pocket Guide explains the most common rules, symbols, and concepts in the ISO Geometrical Product Specifications System. Written by standards expert Alex Krulikowski, this valuable on-the-job reference clarifies how to interpret standard-compliant technical drawings that use ISO 1101:2012 and its companion published standards. More than 15 standards were directly reviewed and more than 30 standards indirectly used in creating the book. One entire section is devoted to a quick comparison of ASME and ISO standards. Author's comments throughout the text provide insights about concepts and how to apply or interpret tolerancing in a cost-effective manner. Drawing interpretation is simplified because the tolerancing information is in one place, logically arranged, with illustrations of each concept.

Kinki University formula project has been participating in the student Formula SAE of Japan (JSAE) every year for the Competition since the second time. The engine uses ZX-6R made by Kawasaki Heavy Industries for the Competition from the eighth time. “Improvement of limited performance” is inserted in the concept through the development of a power train. Supercharger loading, engine dry sump and engine cooling management were improved. 59.6 kW (80.6 PS) /9000 rpm of maximum output and 70.6 Nm (7.2 kgf m)/8000 rpm of maximum torque were achieved by the supercharger loading. We succeeded in getting 90% of torque band (4000∼10000rpm) by 50% of the number of revolutions in regular use (2000∼12000rpm). Using the dry sump system, hydraulic pressure constantly managed hydraulic pressure at the time of engine operations; the system, where the engine stops at the time of hydraulic pressure fall, was also built.

As congestion increases and commute times lengthen with the growing urbanization, many customers will look for effective mobility solutions. Two-wheeler are one of the solutions to deal with these issues, in particular if equipped with electrified powertrains for minimized local noise and air pollutant emissions. Scooters powertrain technology is predominantly based on Spark Ignition Engine (ICE) associated with a Continuously Variable Transmissions (CVT) and a Centrifugal Clutch. Nevertheless, even though CVT gives satisfaction in simplicity, fun to drive, cost effectiveness and vehicle dynamics, its efficiency is an undeniable drawback. Indeed, a conventional CVT is wasting more than 50% of ICE effective power in customer driving conditions. Consequently, those vehicles have high fuel consumption relative to their size, and are equipped with overpowered and heavy internal combustion engines, allowing a large area for further improvements.

In consideration of the fact that in extreme Enduro competitions two-stroke motorcycles are still dominating, the Institute of Internal Combustion Engines and Thermodynamics, Graz University of Technology, with a long tradition in two-stroke technology, has developed a new 300 cm3 two-stroke motorcycle engine. The 2-stroke LPDI (Low Pressure Direct Injection) technology was originally developed for the 50 cm3 Scooter and moped market in Europe. In 50 cm3 applications the LPDI technology fulfils the EURO 4 emission standard (2017) [1]. In a next step the LPDI technology was applied to a 250 cm3 Enduro engine demonstrator vehicle. Based on the results of the demonstrator, a complete new high performance 300 cm3 engine was developed. The development of this new engine will be described in this publication. Some interesting aspects of the layout with 3D-CFD methods and also 1D-CFD simulation to optimize the exhaust system by DoE methods are discussed in the paper.
