The article is devoted to the study of performance indicators of diesel fuel with the addition of rapeseed oil ether. To do this, the study used diesel fuel of Euro 5 grade “L” and the following dietary supplements: rapeseed oil methyl ester and rapeseed oil isopropyl ester. In the resulting biofuels the corresponding physical and chemical properties were determined. Based on the results of research, it was found that the complex of quality indicators of diesel fuel of petroleum origin and samples of rapeseed oil esters slightly differs from the indicators of petroleum diesel fuel, and, also, number of indicators of environmental properties are better than those of fuel of petroleum origin.

The purpose of this publication is to analyse the impact of different composition of motor biofuel mixtures on their performance properties. The use of alcohols as an additive to gasoline has a number of advantages; in particular, it reduces the amount of carbon monoxide and nitrogen emissions, as well as emissions of carcinogenic compounds. The use of biofuels will improve environmental and energy security. However, there are a number of disadvantages of such fuels, so the search for solutions to problematic issues when using biofuels with the addition of ethyl alcohol is relevant.
