Descripción
It is very important to have a standard for biodiesel to enable producers of this fuel to guarantee equal quality and to enable car manufacturers to optimize their engines to this product. But there are chemical differences between classical diesel fuel and biodiesel, so in standardizing biodiesel, we find three groups of requirements: - the same as with diesel fuel - some must be adapted to biodiesel - some are new, for they are relevant only to biodiesel. All these old and new requirements are dis cussed in detail. The first standard for biodiesel was the Austrian standard ON C 1190 for rapeseed me thyl ester, followed by ON C 1191 for fatty acid methyl ester. Other European countries fol lowed with their own standards. Now the Eu ropean Community creates a European stan dard. This is not so easy, because some coun tries use 100 percent FAME, some others add 5 percent or so to all diesel fuel in their market. In the meantime, we know a lot of char acteristics on biodiesel, relevant for the per fect use in cars. This is the reason why many car manufacturers already gave their approval for using biodiesel in their engines. But some question remain and we have to gain more knowledge about this new fuel.
