The problem of the military vehicles engines fuelling increases with the growth of the amount of vehicles in the armies. At the same time, another problem with fuel supply in modern engines is the use of bio component additives, which changes characteristics (quality) of the used fuels. Therefore, it is important to take actions to adapt engines to powering with fuels coming from renewable sources.The aim of the research was to evaluate the possibility of feeding the diesel engine (influence on the useful parameters and composi-tion) with mixtures of the unified battlefield fuel F-34/F-35 with biocomponents in the form of anhydrous ethyl alcohol and RME. The tests were conducted during fuelling of the engine with six kinds of fuels: basic fuel (diesel oil), NATO code F-34/F-35 fuel, as well as fuel mixtures: F-34 and RME with different ratio and F-34/F-35 with bioethanol. In the result of the research it was concluded that the parameters of the G9T Renault engine with the common rail fuel system in terms of F-34 and RME consumption (using) decreased in comparison to diesel oil basic fuel. It is not possible to supply the engine with the mixture of ethyl alcohol and F-34 fuel – alcohol pre-cipitation and obliteration of fuel system components

Biodiesel was synthesized using waste chicken oil and ethyl alcohol as reactives as well as denatonium benzoate and tin particles as catalysts in 500 mL three neck flask. The reaction mixtures were mechanically stirred at 200 rpm during 15 minutes at 30, 40, 50, y 60 º C, after that the products were filtered trough a 400 m mesh an then casted in a separating funnel in order to obtain two layers corresponding to glycerol and Biodiesel. The tin catalyst particles were observed by optical microscopy. The biodiesel and glycerol were characterized using refractive index, pH, Fourier transformer infrared spectrometry (FTIR), while the viscosity was determined in a Brookfield viscosimeter and density using a picnometer. The results suggest that at a low concentration of denatonuim benzoate (7 ppm) the reaction will occur only if tin is present at all test temperatures. The pH of biodiesel obtained was 6, similar to petrodiesel used commonly in diesel motors.

The work is devoted to the improvement of the methodological foundations of the refractodensimetric method of analysis as applied to liquid alcohol-containing products of grape winemaking. The regularities of changes in density and specific refraction of ethyl alcohol and substances of the extract of grapes and wine depending on their concentration based on the processing of the data of measuring the refractive index and density of various alcohol-containing products of winemaking and model solutions based on them, as well as based on the analysis of data from official densimetric and refractometric tables to determine the concentration of aqueous solutions of ethyl alcohol and total extract of the must, has been determined. The improved mathematical model of an alcoholic drink is proposed, which adequately describes the dependence of the refractive index and density of the drink on the content of ethyl alcohol and extract, based on the use of the additivity property of the specific refraction and the mass of the components of its constituents. On the basis of the proposed mathematical model of the drink, an algorithm has been developed for determining the volume fraction of ethyl alcohol and the mass concentration of the total extract for winemaking products, based on measuring the density and refractive index as the basis for the method for determining the volume fraction of ethyl alcohol and the mass concentration of the total extract. Preliminary metrological certification of the method for determining the mass concentration of the total extract and the volume fraction of ethyl alcohol in alcohol-containing products of grape winemaking has been carried out. The results of the work can be the basis for the development of a non-destructive express method for determining the volume fraction of ethyl alcohol and the mass concentration of the total extract based on the standard equipment of the laboratory of wineries, as well as the development of technical specifications for the manufacture of a portable device for determining the concentration of alcohol and extract based on the simultaneous measurement of the refractive index and density of liquid media.

Intermediate Fraction

The article studies the effect of introducing an intermediate fraction of fruit distillate into the wort sent for fermentation in order to prevent the development of extraneous microflora, activate the fermentation process and reduce the loss of anhydrous ethyl alcohol in the production cycle of fruit distillates. The optimal technological modes of apple wort fermentation have been established.
