Background. A comprehensive commodity evaluation of the developed motor fuels with the use of biocomponents with the use of expert evaluation was carried out. The advantages in terms of operational and ecological properties over the basic analogues of A-95 gasoline and L-grade diesel fuel of domestic production are proved. The economic efficiency of the developed fuel compositions is proved and substantiated.
Materials and methods. The object of research is motor fuels with biocomponents. The subject of research – operational and environmental properties of motor fuels with biocomponents.
A-95 gasoline and L-grade diesel fuel manufactured by PJSC Ukrtatnafta were identified as basic samples.
Calculation and expert methods were used in conducting a comprehensive assessment of the quality of motor fuels.
The complex quality indicator of the developed A-95 gasoline with biocomponents was determined on the basis of operational and ecological properties according to the following indicators: octane number; fractional composition; density; corrosion on a copper plate; sulfur content; volume fraction of aromatic hydrocarbons; volume fraction of benzene.
A group of qualified experts was involved to establish the ranks of quality indicators.
Results. Experts assessed the importance of selected indicators to assess the level of quality by ranking them.
The comprehensive quality indicator is calculated on the basis of experimental and baseline values of performance and environmental performance indicators to determine the consumer benefits of developed fuels with biocomponents over baseline.
As a result of the calculations, it was determined that the complex quality indicator of the proposed fuels Q> 1, which indicates a higher level of quality compared to the basic fuel samples.
Conclusion. It is established that the complex quality indicators of the developed fuels are for gasoline A-95 with biocomponents – 1.17, and for B L brand with biocomponents – 2.04, which indicates the qualitative advantages of the latter compared to analogues. Thus, in general, comprehensive indicators of the quality of performance of developed fuels with biocomponents prove the feasibility of their production and use in vehicles.
