Flower power - Biodiesel is genuine Flower Power, it is biogenic fuel or, more precisely, a fuel produced from plants. To be very exact: biodiesel is manufactured from high-quality vegetable oils. Biodiesel manufactured and sold in Germany is nearly always manufactured from the most important indigenous oil-bearing plant - rape. The oil is converted into a modern diesel fuel with flow and combustion properties very closely approximating those of conventional mineral fuels by a simple rebuilding process of its molecular chains. Biodiesel thereby fulfils the highest requirements of engine technology such as the modern high-pressure fuel injection systems (Common Rail).
Manufacture - The manufacture of a high-performance biodiesel from pure vegetable oil, a so-called ester interchange process is necessary. Oil and lipid molecules of both vegetable and animal fats always have the same structure. They consist of so-called triglycerides, a compound of the trivalent alcohol glycerine with three fatty acids.
