S obzirom na to da su rezerve nafte, odnosno goriva mineralnog porekla ograničene, sve je aktuelniji trend istraživanja obnovljivih izvora goriva radi supstitucije konvencionalnih goriva. Uposlednje vreme u svetu je aktuelna tendencija supstitucije mineralnih goriva za dizel motore gorivima na bazi biljnih kultura. Direktiva Evropske unije ukazuje na neophodnost supstitucije fosilnog dizel goriva sa 0,75% biogoriva godišnje. U ukupnoj potrošnji biogorivo treba da učestvuje sa 5,75% do 2010. godine, a do 2020. godine sa 20%. U radu su prikazane tehnologije dobijanja biodizela i rezultati ispitivanja dizel motora S-44 sa primenom dizel goriva D-2, biodizela RME i njihovih mešavina. Rezultati navode na konstataciju da je potrebno dalje poboljšavati kvalitet takvih goriva, a naročito njihovih fizičko-hemijskih karakteristika, u skladu sa predloženim standardom za biodizel. / In view of the fact that the reserves of petroleum, i.e. of fuels mineral origin are limited, the trend of research of renewable sources is more and more actual, with the aim to substitute conventional fuels. During the last years, the trend of substituting gasohol of mineral origin with the fuels deriving from vegetable culture is actual world-wide. EU directives are pointed out that is necessary to substitute fossil diesel with 0,75% of biofuel per year. In total consumption of fuels for transportation, to 2010 the biofuel should participate with 5,75% and with 20% to 2020. In this review are technology of biodiesel production and research diesel-motor S-44 with use diesel D-2 fuel, biodiesel RME and their mixtures. The results of the researches suggest that further improvement of such fuels is necessary, and particularly of the physical and chemical characteristics, according to the proposed standard/or biodiesel
