Shell Eco-Marathon

from Wikipedia, the free encyclopedia

The Shell Eco-Marathon (SEM) is a competition to find the least energy-consuming vehicle in the world. The competition is held in different regions of the world and organized by the Shell company . On a course of around 25 kilometers, it is important to use as little fuel equivalent as possible.

history

The history of the race goes back to a bet that Shell scientists made in 1939. The content of the bet was to determine how far you could drive your own vehicle with one gallon of fuel.

In 1985, the SEM in its current form was held in France for the first time . Annually competitions took place at the Rockingham Motor Speedway ( Great Britain , Shell Eco-marathon UK ), the Auto Club Speedway ( United States of America , Shell Eco-marathon Americas ) and the EuroSpeedway Lausitz ( Germany , Shell Eco-marathon Europe ). Until 2008, the European competition took place on the Circuit Paul Armagnac in France. In 2012 it was held in Rotterdam . In 2017, three competitions took place around the world: the Shell Eco-marathon Asia was held in Singapore , the Shell Eco-marathon Americas in Detroit and the Shell Eco-marathon Europe in London . There are also several challenger events that take place around the world.

vehicles

The vehicles are designed with the aim of using as little energy as possible when driving. Streamlined bodies and lightweight construction are used. Special materials such as carbon fibers , Teflon , high-strength aluminum or wood are used. Since the wind attack surface has a decisive influence on the air resistance, the vehicles are very small and in the prototype class suitable for a person without luggage. In the UrbanConcept class , properties are also required that are required in road traffic.

With regard to the type of energy, the vehicles are divided into combustion and electric vehicles:

Belong to the category of internal combustion engines

Belong to the electromobility category

Since 2018 there has been an autonomous category in which a route has to be driven completely autonomously. Consumption also plays a role here.

Horn , rearview mirror and seat belt are just as mandatory in the Urban Concept category as fire extinguishers and roll bars . The maximum width of the vehicles is limited to 1.3 m, with the ratio between height and width not exceeding 1.25. There are no restrictions on the design and use of materials for the vehicles.

The aim of the Shell Eco-Marathon is to drive as long as possible with as little energy as possible. Each vehicle has to cover a distance of 25 kilometers in a maximum of 50 minutes (this corresponds to an average speed of at least 30 km / h). During this journey, the fuel consumption is measured. In order to make the results of the various categories comparable, it is calculated how many (milli-) liters of super gasoline contain the same amount of energy as the fuel consumed. Finally, it is extrapolated how many kilometers the vehicle could theoretically cover with the amount of energy from a full liter of super gasoline.

To compare electrically powered and fuel-powered vehicles, the required amount of fuel in liters or the amount of energy in kWh is converted into the other unit.

Records

Premium gasoline

Urban Concept: The DTU Roadrunners of the Technical University of Denmark achieved 611.1 km / l in 2012 - an increase of 102.1 km / l to the old record.

Synthetic fuel (GtL + E100)

Prototype: In 2012 the Dutch MAC Eco Team achieved 416.3 km / l with a GtL (gas-to-liquid) drive, a record increase of 138 km from the old record.

accumulator

Prototype: In 2014 the TERA TU Graz team set a new record with 1091.6 km / kWh.

Urban Concept: Here the French team Electricar Solutions achieved a range of 262.6 km / kWh in 2012 - an increase of 29.6 km / kWh to the old record.

Hydrogen (fuel cell)

Prototype: The current record for prototypes was set in 2010 with 4896 km / l by the Polytech Nantes University team with the Polyjoule fuel cell vehicle - an increase of 1060 km / l on the old record.

criticism

This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

The Shell company is repeatedly accused of not being interested in the new technologies that this competition brings to light, but of using the competition as a marketing tool. These arguments are supported by the fact that the Eco-Marathon does not attach any importance to the fact that the vehicles in the prototype class are suitable for everyday use. Switching off the motor after reaching the highest speed also differs from practice. Furthermore, support from muscle power in the drive - which can also save fuel - is not desired.

Live broadcasts

Students from the Faculty of Media and Information at the Offenburg University of Applied Sciences have been broadcasting the Shell Eco-Marathon live on the Internet since 2008.
