Истощение запасов нефтяных топлив и неуклонный рост их потребления потребуют новых решений в освоении технологий на возобновляемых источниках энергии. Исследование возможности применения альтернативных топлив в двигателях внутреннего сгорания – комплексная научная задача, включающая изучение влияния альтернативных топлив на эффективность работы действующих силовых установок.</p><p>Цель исследования – получить скоростную характеристику дизеля при работе на этиловом спирте и запальном рапсовом масле.</p><p>Методология и методы. В качестве объекта исследования выбран тракторный дизель размерности 2Ч 10,5/12,0 воздушного охлаждения с объёмным смесеобразованием. В ходе исследования использовали сравнительный метод. Скоростная характеристика снималась при фиксированной цикловой подаче топлива после выхода двигателя на номинальный режим работы при частоте вращения коленчатого вала 1800 мин-1 и среднем эффективном давлении в цилиндре 0,588 МПа. Такой подход при отключенном всережимном регуляторе топливного насоса позволял выявить основные закономерности внутрицилиндровых процессов при различных скоростных режимах работы двигателя.</p><p>Результаты и научная новизна. В статье представлены результаты стендовых испытаний дизеля при работе на различных скоростных режимах на этаноле и рапсовом масле и подробно проанализированы основные показатели процесса сгорания и эффективные показатели работы двигателя по сравнению с использованием традиционного топлива.</p><p>Практическая значимость заключается в возможности использования полученных результатов для совершенствования работы дизелей на альтернативных возобновляемых топливах.</p></abstract><trans-abstract xml:lang="en"><p>Introduction (problem statement and relevance). The depletion of oil fuels reserves and the steady growth of their consumption will require new solutions in the development of technologies based on renewable energy sources. The study of the possible alternative fuels use in internal combustion engines is a complex scientiﬁc task, including the research of the alternative fuels effect on the power plants operation efﬁciency.</p><p>The purpose of the study was to obtain the speed characteristics of a diesel engine operating on ethyl alcohol and rapeseed oil.</p><p>Methodology and research methods. An air-cooled with volumetric mixture formation tractor diesel engine of dimension 2Ch 10.5/12.0 was selected as an object of research. The study was carried out by a comparative method. To measure the speed characteristic a ﬁxed cyclic fuel supply was applied after the engine reaching the nominal operating mode at a crankshaft speed of 1800 min-1 and an average effective pressure in the cylinder of 0.588 MPa. This approach, with the all-mode regulator of the fuel pump turned off, made it possible to identify the main regularities of intra-cylinder processes at different speed modes of engine operation.</p><p>Scientiﬁc novelty and results. The article presents the bench tests results of a diesel engine operating at various speed modes on ethanol and rapeseed oil, and analyzes in detail the main indicators of the combustion process and the effective engine performance in comparison to the use of traditional fuel. The practical signiﬁcance lies in the possibility of using the obtained results to improve the diesel engines operation on alternative renewable fuels.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дизель</kwd><kwd>топливо</kwd><kwd>тепловыделение</kwd><kwd>альтернативные топлива</kwd><kwd>этанол</kwd><kwd>рапсовое масло</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diesel</kwd><kwd>fuel</kwd><kwd>heat release</kwd><kwd>alternative fuels</kwd><kwd>ethanol</kwd><kwd>rapeseed oil</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">Бендик М.М., Фомин В.М., Хайсам А.Г. и др.
