The article considers the issue of developing a technical and technological solution to ensure stable supply, dosing and effective mixing of a four-component two-phase mixture directly in the engine combustion chamber. The relevance of the study is due to the need to increase the completeness of fuel combustion, improve the energy and environmental performance of the engine, as well as ensure controlled formation of the fuel-air mixture under variable operating conditions. The functional structure of the component supply system is substantiated, the requirements for dosing, mixing and spraying elements are determined, as well as for coordinating the flow rates, pressure, temperature and phase state of the components. A basic scheme for forming a two-phase flow is proposed, which involves the phased introduction of the mixture components, preliminary dispersion of the liquid phase and subsequent intensification of mixing in the injection zone. Particular attention is paid to ensuring the homogeneity of the mixture, flame stability, reducing the size of the drops and increasing the rate of mass and heat transfer. The methodological basis of the work is the analysis of the mixture formation processes, structural and functional modeling of the system and evaluation of the main operating parameters. The influence of the design parameters of the mixing unit, the geometry of the channels, the ratio of components and feed modes on the quality of mixture formation is considered. An algorithm for controlling the supply of components depending on the load and thermal state of the engine is formed. The proposed solution creates the prerequisites for increasing the combustion efficiency of the four-component mixture, reducing the unevenness of its distribution in the combustion chamber and improving the engine performance. The results obtained can be used when designing and modernizing fuel systems of engines operating on multi-component alternative fuel compositions.

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.
