The use of supercharged diesel engines improves the combustion process, increases the efficiency of the engine and the overall efficiency of its operation. As a concomitant beneficial effect, there is an increase in the environmental performance of the engine. All of the above factors are particularly relevant for solving the problem of converting so-called "atmospheric" diesel engines into turbocharged engines, and the objects of conversion can be a fleet of old engine models that have not exhausted their resource. The results of the research of this article can be used for the implementation of the association agreement between Ukraine, on the one hand, and the European Union, the European Atomic Energy Community and their member states, on the other hand, in particular, Chapter 6 and Chapter 17 of Chapter V. The purpose of the article is creation of a methodology for determining turbocharger parameters, based on engine intake process parameters and selection, based on these parameters, of a turbocharger model for conversion of "atmospheric" turbocharged diesels. The research methods are based on the thermal calculation of the Hrynevetsky-Mazing engine, the calculation of the regulatory characteristic of the engine according to the cubic trinomial equation, the determination of the characteristic modes of the engine according to the regulatory characteristic, the calculation of the air consumption by the engine depending on the speed of rotation of the crankshaft in different modes of operation of the engine and the superimposition of the obtained results of the air consumption on the "turbo card" of the turbocharger, which allows you to establish the correspondence of the turbocharger model to the engine brand. Calculations were carried out using the mathematical editor Mathcad and Microsoft Excel spreadsheets.
The results of the obtained calculations and the methodology can be the basis for the development of recommendations for the choice of a turbocharger when converting "atmospheric" diesel engines with turbocharging. Such recommendations will be useful to agricultural producers, in which the tractor fleet has old brands of tractors with non-supercharged engines that have not exhausted their resource.

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.
