In accordance with an EU directive, conventional automotive diesel is supplemented with seven percent biodiesel. This proportion is set to rise to ten percent by 2020. However, this presents a significant technical challenge: biodiesel vaporises at higher temperatures, which can lead to problems with electronic fuel injection systems and particulate filters. Researchers from Kaiserslautern, Bochum, and Rostock have developed a method for producing a petroleum diesel-like fuel from conventional biodiesel at low temperatures. (2017-06-19)
