Отметили, что правильно спроектированная система охлаждения в дальнейшем гарантирует поддержание оптимального теплового режима работы двигателя. Предложили медодику расчета теплоносных характеристик системы охлаждения для заблаговременного исключения возможных проблем, связанных с повышенным износом деталей, преждевременной потерей маслом смазывающих свойств, перегревом двигателя (отдельных агрегатов) и трущихся деталей, снижением мощности двигателя и ухудшением качества топливо-воздушной смеси, поступающей в цилиндры.</p><p>Цель исследования Разработать методику расчета количества теплоты, которое должно быть рассеяно масляными радиаторами жидкостной системы охлаждения (системы смазки) при различных нагрузочных и скоростных режимах работы двигателя.</p><p>Материалы и методы Предложили определить количество теплоты, которое должно быть рассеяно жидкостно-масляным теплообменником системы охлаждения смазочного масла двигателя.</p><p>Результаты и обсуждение В методике расчета масляных радиаторов представили расчет тепла, полученного маслом в процессе работы автотракторных двигателей мощностью 37-110 киловатт. Определили теплорассеивающую способность масляной поверхности. Выявили параметр, учитывающий тепловой поток масляных радиаторов. Представили графики зависимости масляной поверхности и теплового потока от мощности двигателя.</p><p>Выводы Разработали методику расчета показателей температурно-динамических характеристик охлаждающей системы автотракторных двигателей, которая позволяет проводить исследования по теплотехническим показателям радиаторов на различных режимах работы машин и теплоносителях систем, конструкционных материалах (металл, полимер) теплообменников с учетом факторов и режимов работы с погрешностью 1,5-8,0 процентов.</p></abstract><trans-abstract xml:lang="en"><p>The paper highlights the relevance of the problem of determining the amount of heat supplied by an internal combustion engine to a liquid cooling system when creating typical series of unified heat exchangers for tractor and combine engines (power units). A properly designed cooling system further guarantees the maintenance of the optimal thermal mode for the engine operation. A methodology for calculating the coolant characteristics of the cooling system was proposed in order to prevent possible problems related to increased parts wear, early loss of oil lubricating properties, the engine (individual units) and rubbing parts overheating, a decrease in engine power and a deterioration in the quality of the fuel-air mixture entering the cylinders.</p><p>Research purpose To develop a methodology for calculating the amount of heat to be dissipated by the oil radiators of a liquid cooling system (lubrication system) being exposed to various load and engine speed modes.</p><p>Materials and methods It was proposed to determine the amount of heat to be dissipated by the liquid-oil heat exchanger of the engine lube oil cooling system.</p><p>Results and discussion The calculation method for oil radiators presents the calculation of the heat obtained by oil during the operation of 37-110 kilowatts automotive engines. The heat-dissipating ability of the oil surface is determined. A parameter taking into account the oil radiator heat flow is identified. The graphs of the oil surface and heat flux dependence on the engine power are presented.</p><p>Conclusions The method for calculating the temperature and dynamic characteristics of the automotive engine cooling system has been developed. It makes it possible to carry out research on the radiator thermal and technical characteristics in various operating modes of machines and coolants of systems, various heat exchanger structural materials (metal, polymer), with an error of 1.5-8.0 percent.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>масляный радиатор</kwd><kwd>автотракторный двигатель</kwd><kwd>жидкостно-масляный теплообменник двигателя</kwd><kwd>сис­тема охлаждения смазочного масла двигателя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oil radiator</kwd><kwd>autotractor engine</kwd><kwd>automotive engine</kwd><kwd>liquid-oil engine heat exchanger</kwd><kwd>engine lube oil cooling system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shimizu S., Sato M., Koyanagi J., et al.
