Emissionen bei der Verwendung von Rapsöl, RME oder Dieselkraftstoff sowie vergleichende Abschätzung ihrer Umweltwirkungen : Eine Übersicht

Based on the extensive literature about exhaust gas emissions of rape seed oil and its methylester (RME), the available data was compiled and distinguished with regard to the used fuels, motors and motor test procedures. To estimate the environmental relevance of the biofuels versus Diesel fuel, in a second step the effects of single exhaust components are described. In the result, it becomes obvious that environmental advantages and disadvantages occur when rape seed oil or RME are used, but RME seems to have fewer disadvantages than rape seed oil. To achieve a sound estimation of the environmental relevance of these bio fuels it will be necessary to determine some more components of the non-limited exhaust gases. Also, at present, the mutagenic, carcinogenic and cytotoxic potentials of the exhaust gas emissions derived from rap seed oil and RME have been insufficiently investigated. For a utilization of these alternative fuels in areas with high NOx levels it is very important to determine their ozone forming potentials in comparison with Diesel fuel
