Production And Study Of Bio Gazolines

Combustible ethanol was obtained from agricultural waste. Test samplesE0 (petrolgazoline) and E5, E10 and E20 (epanpl/gazoline blend) were prepared and their physical, chemical and technical characteristics were studied. The effect of bioethanol on the ecological compatibility of the automobile engine has been studied. The objects of research were Regular, Premium and Super of Petrol gasoline Samples, as well as a of 10%, 20% and 30%. bioethanol/gazoline blends. The study of the ecological properties of the test additive was carried out at the stand of automobile engines SAK-670 (Germany), on which the engine of a BMW-316 car with coupling sleeve and a transmission assembly is installed. The stand is equipped with brakes and torque sensors, as well as with crankshaft speed and fuel consumption measuring instruments. The test mixtures during an idle running of engine cause a decrease in the CO content in the exhaust gases by 10-16%, and this taking into account their low cost, indicate the prospect of expanding the use of fuel ethanol

Study of tribotechnical and ecological efficiency of motor car transmission oil “Kolkheti–2” prepared with nanotechnology

The paper refers to the research results of influence of motor car transmission oil prepared with nanotechnology on pitting resistance of friction knots and engine fuel consumption. herewith the advantage of test oils compared to corresponding oils of famous firms is shown

Study of tribological efficiency of new type additive to oils

2-s2.0-84905815557 - ScopusHigh tribological efficiency of amorphous finely dispersed carbon (AFDC) received in the form of waste during methane pyrolysis (CMP) has been shown earlier. The multifunctional mechanism of its action is based on the new phenomenon, which consists in AFDC ability to form in the process of friction secondary surface structures, containing phases of nano-dispersed diamond, graphite, AFDC and providing high functional properties of oils containing CMP. By means of studies carried out in the mentioned aspect a new high effective multifunctional additive to oils is revealed, which represents synthesized amorphous nano-dispersed carbon doped by ironVytauto Didžiojo universitetasŽemės ūkio akademij
