Diagnostics and forecasting of the resource is one of the most important factors in managing the efficiency and operational reliability of agricultural machinery. Increasing the requirements for the quality of technical maintenance requires improving approaches to assessing the condition of the engine, which is considered as a system of series-connected elements without redundancy. The purpose of the article is to analyze existing methods for non-disassembly diagnostics of auto-tractor diesel engines and to justify the feasibility of using the pattern recognition method for small deviations of parameters to predict the residual resource. The research methods are based on the analysis of the theory of similarity and dimensions, as well as methods of mathematical statistics and probability theory.
The laws of failure distribution (normal, Weibull, exponential, Rayleigh, gamma distribution) and their application to various types of wear are considered in detail. The research found that classical statistical methods, in particular the normal distribution law, require a large amount of testing, which complicates their use for operational forecasting. The results of the analysis allowed us to substantiate the effectiveness of the pattern recognition method, which allows us to record hidden changes in structural parameters within the tolerance range. The proposed approach allows us to reduce the amount of computational work and increase the accuracy of individual forecasting of the resource of a particular unit.
The results of the work will be useful for engineering and technical workers of the agro-industrial complex in solving the problems of reducing the variability of the resource of engines and their systems, providing the possibility of prompt detection of pre-failure states based on small deviations of parameters for more accurate forecasting of the durability of equipment.

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.
