Yuriy Paladiychuk – Candidate of Science (Engineering), Associate Professor of the Department of Agroengineering and Technical Service of Vinnitsa National Agrarian University (3 Soniachna St., Vinnitsa, 21008, Ukraine, e-mail: rewet@vsau.vin.ua).
Inna Telyatnuk – 4th year student of specialty 208 of Agroengineering, Faculty of Engineering and Technology of Vinnytsia National Agrarian University (3, Solnychna st., Vinnytsia, 21008, Ukraine, e-mail: inna201098@gmail.com) .
Annual emissions of more than 6 million tons of pollutants and carbon dioxide into Ukraine. Mostly polluting industrial enterprises. However, with the increase in the number of cars on the roads, the number of harmful emissions into the atmosphere has increased. Over the past few years, the amount of exhaust gas entering the air in major cities has increased by 50-70%. More than half of the pollutants are emitted by private cars: in 2019, 1.7 million tonnes of harmful substances fell on them, while the total amount of all car emissions was 2.3 million tonnes.
This article highlights the problem of environmental pollution by the exhaust gases of diesel internal combustion engines. Ways to improve environmental performance are presented. The composition of the exhaust gases and their effects on the environment are analyzed. The standards of Euro - 1 Euro - 6, on the reduction of harmful substances in diesel fuel are considered. The modern environmental standards of Stage and Tier and the regulation of smoke by standards are given. A formula for the determination of harmful substances in the exhaust gases of cars and a formula for the determination of the smoke of gases are proposed. The ways of neutralizing the toxicity of the exhaust gases with the help of neutralizers and the reduction of soot by means of the diesel particulate filter are considered. Common Rail DRNR systems, EGR and Selective Neutralization (SCR) systems using Adblu reagent, its advantages and disadvantages are described. The comparative characteristics of EGR and SCR systems are presented.
Gasoline engines are not considered in this 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.
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.
