(Source: Kai Pfister)In accordance with an EU directive, conventional automotive diesel is supplemented with 7 percent biodiesel, a proportion set to rise to 10 percent by 2020. This presents a technical challenge as biodiesel vaporizes at higher temperatures, which can lead to problems with electronic fuel injection systems and particulate filters in conventional diesel engines.

Researchers in Germany have developed a new method for producing a petroleum diesel-like fuel from conventional biodiesel at low temperatures. This biofuel can be used undiluted in modern diesel engines or mixed in any ratio with petroleum diesel. The addition of ethylene, which can be generated from bioethanol, transforms the long chains of rapeseed oil esters into a mixture of shorter chains, resulting in a fuel that combusts at lower temperatures.

The new biodiesel, processed without the use of solvents, was used to power a self-made model car.

Researchers from University of Kaiserslautern, University of Rostock, and Ruhr-Universität Bochum participated in this project.
