As early because the starting of the 20 th century Rudolf Diesel proposed vegetable oil as gas for his engine. a little while later, prior to and through international conflict , vegetable oil was once tested in "up-to-date" diesel engines. In 1940 first trials with vegetable oil methyl and ethyl esters have been conducted in France and, whilst, scientists in Belgium have been utilizing palm oil ethyl ester as a gasoline for buses. In 1973, the oil predicament refocused realization on and curiosity for neighborhood power resources. In contemporary a long time, examine touching on and information concerning the exterior merits of renewable uncooked fabrics have intensified the efforts for sustainable strength resources. Biodiesel performs a huge function during this box as a result of the world-wide examine, improvement and deployment actions of this sustainable strength resource.

Biodiesel: Basic facts The production costs varied greatly according to plant scale and process. In Tab. 8 some scenarios for different plant sizes and oil price levels were calculated: Small scale, high raw material price Small scale, low raw material price Large scale, high raw material price Large scale, low raw material price Rape oil price €/kg Conversion costs €/kg Biodiesel price €/kg 0,6 0,3 0,6 0,3 0,2 0,2 0,05 0,05 0,8 0,5 0,65 0,35 Tab. : Biodiesel in Europe, System Analysis, Non-Technical-Barriers, Wels 2000, p.
551 Cetane number The Cetane number is an indication of a fuels readiness to autoignite after it has been injected into the diesel engine. Diesel fuel for use in on-highway engines is required to have a Cetane number of 40 or higher. Since a higher Cetane number translates into higher fuel costs, most refiners keep the Cetane number of their diesel fuels between 40 and 45. Current research shows that Biodiesel's higher Cetane number (generally between 46 and 60 depending on the feedstocks used to make the Biodiesel) shortens the ignition delay.
