TERNARY FUEL COMPOSITIONS CONTAINING BIODIESEL, PLANT OIL AND LOWER ALCOHOLS FOR FEEDING DIESEL-CYCLE MOTORS

摘要

Fuel compositions based on biodiesel, lower alcohols and plant oil for feeding Diesel cycle engines, enabling more perfect burning, less emission of pollutants and less formation of internal deposits of impurities onto the inner surface of engines. Since the blends exhibit density similar to that of diesel oil, as well as chemical affinity for the latter (since it contains biodiesel, which performs the function of co-solvent), the present invention also relates to compositions of quaternary blends, that is, junction of the ternary blends proposed (biodiesel, lower alcohol and vegetable oil) with petroleum diesel in the most varied proportions. The preferred embodiment of this invention provides the replacement of fuel of non-renewable source (diesel oil) by others of renewable source, which are natural, non-toxic, biodegradable and that have excellent technical performance.
