Jatropha Oil as an Alternative Fuel for Modern Diesel Engines

An effective way to reduce greenhouse gas emissions (GHGs) is to use rurally produced straight jatropha oil as a substitute for diesel fuel. However, the different physical and chemical properties of straight vegetable oils (SVOs) require a customized setup of the combustion engine, particularly of the injection timing and quantity. Therefore, this study demonstrates the differences in the injection and combustion processes of jatropha oil compared to diesel fuel, particularly in terms of its compatibility with exhaust gas recirculation (EGR).

2nd Generation Pure Plant Oil in Flex Fuel Engines

Since 2001 four oil spills from tank ships threatened Ecuador’s Galapagos Islands, killing over 10.000 marine iguanas and other species. As consequence to the Ecuadorian „Zero Fossil Fuel on Galapagos Island Initiative“ 100 % renewable energy hybrid systems with photovoltaic, wind, battery and pure plant oil (ppo) generators for frequency control/grid balancing have been installed 2010 on Floreana Island.

Pure Jatropha Oil for Power Generation on Floreana Island/Galapagos

In the small country of Ecuador, all environmental risks of the production and consumption of fossil fuels can be observed by damages through oil exploration in the amazonite rainforest and two tank ship accidents close by Galapagos Islands. Now Ecuador plans to replace all environmentally dangerous diesel generators from all four inhabited Galapagos Islands by a hybrid system using 100 % renewable energy for electricity production. Since 2010 a hybrid system of two Jatropha oil generators and a photovoltaic plant is successfully providing electricity from renewable energy for inhabitants and tourists of Floreana Island.

Biokraftstoff: Quo vadis?

Biokraftstoffe sind in die Kritik geraten. Schon rudert die Politik zurück. Müssen wir die ambitionierten Ausbaupläne begraben oder gelingt es, für Biosprit eine nachhaltige Produktion und Verwendung zu finden?

2nd Veg Oil Project

When used at a local level, Pure Plant Oil (OOP), has a potential for the most comprehensive benefits of all engine biofuels. However, like any other fuels, it will soon have to comply with severe emission standards, including a drastic decrease of particle emissions.

Long-term Experience with Pure Plant Oil

This paper reports on results of 10 years experience with diesel motor adaption to bi-valent pure plant oil (PPO)/diesel operation. Vereinigte Werkstätten für Pflanzenöltechnologie (VWP) holds 7 patents and 1 registered design on this topic. Further patents on the latest development results have been applied for. The closed-circuit management of PPO was a project of the EXPO 2000 in Hannover. Within the German 100 tractor programme, at present 56 tractors have successfully been converted with VWP technology and run with PPO.

Expo 2000 Projekt

Durch die VWP-Entwicklungen am Serienmotor wird die Anwendung von reinem Pflanzenöl als Kraftstoff serienreif. Die Serien- und Alltagstauglichkeit wurde durch Flottenversuche mit 150 Fahrzeugen dokumentiert, die über mehr als sechs Jahre liefen und durch das Bayerische Wirtschaftsministerium und das Baden-Württembergische Landwirtschaftsministerium finanziell unterstützt wurden.

Reproduktionspreis fossiler und nachwachsender Kraftstoffe

Die heutige Energieversorgung der Menschheit beruht darauf, dass mann vermehrt einen zwar leicht verfügbaren, aber doch begrenzten Vorrat insbesondere flüssiger fossiler Energieträger verzehrt. In der Ressourcenökonomie kommt die Endlichkeit dieser Erdölvorräte ungenügend zum Ausdruck.
