the possibility of using jatropha oil as a basis to become an organic biofuel, the comparative analysis of physical, chemical, fuel characteristics of jatropha oil and diesel fuel and the basic parameters of functioning of diesel engines to biofiiel mixtures based on Jatropha oilwere discussed We have designed a technological of producing biofuelfrom jatropha seeds and its introduction in machinery tractor Keywords: Jatropha culture, organic biofuel, process Ing lechnology.substitulion of diesel fuel BACKGROUND There are many popular crops that producing biodiesel fuels over the world such as rape, soybeans, etc - but most of them require an intensive care and not grow in all areas The presence of relatively cheap raw materials has been the basis for tbe development of biodiesel industry One ofthe perspective crops for biofuel production is jatropha.lt is a genus of flowering plants in the spurge family, Eupborbiaceae.lt contains approximately 170 species of succulent plants, shrubs and trees Jatropha curcasis one of the best candidates for future biodiesel production It is perennial tree or shrub that easily spreads by seeds and propagates by grafts Although it grows well in tropical and subtropical climates, it can be planted throughout the world It is also more commonly known as the perennial tree-weed growing on poor dry soil [1] Nutrient content in soil is not the main factor affecting the productivity of jatropha It can grow on both fertile soils and soils with low humus content Today jatropha is grown in many tropical countries, where tbe amount of annual rainfall is 300-1000 mm and average temperature above 18-2D°C, including India and China with large-scale planting of jatropha (900 000 * Tel- 79281570500 Email- v i.pakhomov%mail-r\ hectares in 2008 with plans for planting at 12.8 million hectares in 2015) In 2015, Vietnam planned to allocate about 300,000 hectares of land for the jatropha cultivation [1] MATERIAL AND METHOD The object of this work is the oil pressed from the Jatropha seeds planted in Phu Tho Vietnam, the nature of the fuel mixture Jatropha oil and diesel, the ability of producing biodiesel from Jatrophaoil in the system JatrophoBIODON-1 and BlOSOIL-200 To achieve the purpose of this work we used analytical methods to determme the quality of fuel Jartopha (GOST 305-82 and GOST R 53605-2009 Russian Federation), methods of empirical research, testing engine is processed bycomputer with software Dasylab 6.0 Results of theoretical and experimental study are compared by the method based on the Buckingham theorems that counts Euler and Reynolds number Figure {.Jatrophaseeds Pakhomov V.l vd Dtg Tap chi KHOA HOC & CONG NGHE Uti.ut^ JVJ -
