SIMULATION OF THE MIXING PROCESS OF DIESEL AND BIOFUELS
Irina Gunko – Candidate of Technical Sciences, Associate Professor of the Department of Agricultural Engineering and Technical Service, Vinnytsia National Agrarian University (Solnechnaya St., 3, Vinnytsia, 21008, Ukraine, e-mail: maniy@ukr.net, https://orcid.org/0000-0001-5470-7413)
The viscosity of a fuel depends on its hydrocarbon composition. Vegetable oil is considered an alternative to diesel fuel. Its high viscosity makes it difficult to consider as a commercial diesel fuel. Vegetable oil is lipids, fatty acid esters. They have a high calorific value and contain straight hydrocarbon chains, resulting in their relatively high cetane number. Viscosity and density determine the evaporation and mixing process in an engine, as they affect the shape and type of the fuel flame, the size of the droplets formed, and how they enter the combustion chamber. Low density and viscosity provide better fuel injection; with an increase in the diameter of the droplet, its complete combustion decreases, therefore, the specific fuel consumption increases and the smoke of the exhaust gases increases.
The viscosity of the fuel affects the pump flow and fuel leakage through the piston pair clearance. As the viscosity decreases, the amount of diesel fuel leaks between the plunger and bushing increases, resulting in a decrease in pump flow. Converting the engine to a fuel with a lower density and viscosity will result in burnout of the piston head, so the fuel equipment needs to be adjusted. Plunger wear is viscosity dependent. It fuel is in the range of 1.8-7.0 mm2/s, which practically does not affect the durability of modern high-speed diesel equipment.
Consider using vegetable rapeseed oil as an alternative to diesel fuel. Its viscosity can be reduced by chemically converting esterification to ethyl esters. When the cheese rapeseed oil is heated to 80 °C, it will give a viscosity value similar to that of commercial diesel. The mixing system will have an operating power equivalent to that of a diesel engine when heated to 40-50 °C.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production.
During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured.
Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
