USING OF BIOETHANOL FUELS IN IC ENGINE
F. Farkas, T. Molnár
Renewables - excluding large hydro accounted for 48% - increased to 15.2% of world cumulative generation capacity in 2014, from 13.8% in 2013. In the EU, the European Parliament approved a reform of the 2020 biofuels target. The new version of the Renewable Energy Directive (RED) distributes the 10% cal. biofuels target into a share for crop-based biofuel (limited at 7% cal.) with the rest to be met with another biofuels and renewable electricity containing multiple counting possibilities. Merely 2% of the EU’s fuel consumption can be covered by its own researches, which looks good pretend a strong dependence on the oil exporting countries. The implementations of biogenic fuels produced from fast growing plant is continuously gaining in importance with regard to economic and environmental effects. Generally they are not offered in their pure form but just as blend components to conventional fuels. Their mixtures can bring about fundamental feature improvements. Ethanol fuel output in 2015 reached a peak high helped by rising gasoline demand in the US. Besides, the changes in the fuel taxation in Brazil and an increase in the minimum blending ratio also pushed along the ethanol fuel demand. The weaker euro and low grain prices on the back of a record wheat crop turned into a considerable growth in output in the EU. Disregard the stimulating developments on the legislative side, it must also be confessed that the decreasing crude oil prices took their customs on the 2015 biofuel markets. For ethanol fuel, more growth could theoretically arrive from an extending of E-10 in EU member states. Unnecessary to discuss that an outlook for a post-2020 biofuels target at the EU level does not valid.
