Modernization and conversion of agricultural machinery to alternative fuels is a key tool for improv-ing its environmental and economic performance. The use of liquefied petroleum gas (LPG) in dual-fuel systems allows for a significant reduction in emissions of harmful substances (CO2, CO, NOx), however, the successful conversion of serial tractor diesel engines with the provision of stable operational characteristics at all load modes remains an unsolved scientific and practical prob-lem. The purpose of the work is to develop methods and techniques for experimental research of a diesel engine in a gasodiesel cycle, which ensures its stable operation at various load-speed modes with different fuel mixture compositions.
To implement the tasks set, an original schematic diagram of the gas-diesel engine power supply system with a mechanical device for manual adjustment of the position of the high-pressure fuel pump (HPFP) rail of the UTN-5 type was developed, which made it possible to eliminate the instabil-ity of the standard all-mode regulator. Experimental studies were carried out on a KI-5542 brake running-in stand based on a four-cylinder diesel engine 4F11.0/12.5, additionally equipped with gas cylinder equipment, a panel rotameter LZM-15ZT-4 and an electronic gas flow weight control sys-tem. The tests were performed according to the “loading - unloading” cycle. The least squares meth-od (LSK) was applied to build mathematical models of trends of the main parameters.
Graphical and mathematical dependences of hourly fuel consumption (Gg, Gdp) and torque (Mk) on the effective engine power (Ne) were constructed. It was established that the torque demonstrates a clear linear dependence on power. The influence of thermal and fuel inertia in the form of a "load-unload" loop was revealed. It was proved that the maximum intensity of liquid fuel substitution by gas is achieved in the middle power range. During the comparative analysis, at the same power, the maximum degree of diesel fuel substitution by gas was recorded, without the risk of detonation phenomena. For comparison, fuel consumption in a purely diesel mode was studied. The proposed method and the developed experimental setup confirmed their full operability and can be used to remove the characteristics of full load and serial conversion of autotractor engines. The results of research work 0125U000363 are presented in this scientific article.

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.
