Потребность автотранспорта в моторных топливах растёт от года к году. Ограниченность нефтяных ресурсов приводит к необходимости поиска решений по замене этого топлива альтернативным. К этому также подталкивает сложившаяся неблагоприятная экологическая обстановка. Вопрос о возможности применения альтернативных топлив в уже существующих двигателях требует исследования их влияния на различные аспекты работы двигателя, включая процессы топливоподачи и сгорания в цилиндре двигателя.Цель исследования – получить характеристики топливоподачи и сгорания в дизеле при работе на метаноле и метиловом эфире рапсового масла.Методология и методы. В качестве объекта исследования выбран тракторный дизель размерности 2Ч 10,5/12,0, воздушного охлаждения, с объёмным смесеобразованием. Характеристики, представленные в работе, снимались на номинальном режиме при частоте вращения коленчатого вала n = 1800 мин-1 и среднем эффективном давлении в цилиндре pe = 0,588 МПа, а также на режиме максимального крутящего момента n = 1400 мин-1, pe = 0,594 МПа. Подача запального топлива на всех режимах фиксирована. Установочные углы опережения впрыска топлива постоянны и составляют 34° поворота коленчатого вала до верхней мёртвой точки для каждого вида топлива.Результаты и научная новизна. В статье представлены результаты стендовых испытаний дизеля при работе на метаноле и метиловом эфире рапсового масла на двух характерных режимах. Представлены показатели процесса топливоподачи и сгорания в цилиндре дизеля. Анализ данных показателей позволяет установить влияние процесса подачи топлива на характеристики сгорания в двигателе.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 (statement of the problem and relevance). The need for vehicles motor fuels is growing from year to year. Limited oil resources lead to the need to replace them with alternative ones. The necessity to find a solution of the problem is also encouraged by the current unfavorable environmental situation. The possibility of using alternative fuel resources in existing engines requires the study of their influence on various aspects of engine operation, including the process of fuel supply and combustion in the engine cylinder.The purpose of the current research was to obtain the characteristics of fuel supply and combustion in a diesel engine operating on methanol and methyl ester of rapeseed oil.Methodology and research methods. As an object of study, a tractor diesel engine with a dimension of 2Ч 10.5/12.0 air-cooled with volumetric mixing was chosen. The characteristics presented in the work were taken in the nominal mode at the crankshaft speed n = 1800 rpm and the average effective pressure in the cylinder pe = 0.588 MPa, as well as in the maximum torque mode n = 1400 rpm, pe = 0.594 MPa. Pilot fuel supply in all modes was constant and fixed. The fuel injection advance setting angles were also constant and amounted 34° of the crankshaft rotation to the top dead center for each of the fuels.Scientific novelty and results. The article considered the bench tests results of a diesel engine operating on methanol and rapeseed oil methyl ester in two characteristic modes. The indicators of fuel supply and combustion process in the diesel cylinder have been presented. The analysis of these indicators allowed determining the influence of the fuel supply process on the combustion characteristics in the engine.The practical significance lies in the possibility of using the obtained results to improve the operation of diesel engines on alternative renewable fuels.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дизель</kwd><kwd>топливо</kwd><kwd>тепловыделение</kwd><kwd>топливоподача</kwd><kwd>альтернативные топлива</kwd><kwd>метанол</kwd><kwd>метиловый эфир рапсового масла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diesel</kwd><kwd>fuel</kwd><kwd>heat generation</kwd><kwd>fuel supply</kwd><kwd>alternative fuels</kwd><kwd>methanol</kwd><kwd>rapeseed oil methyl ester</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">Saccullo M., Ny-gren A., Benham T., Denbratt I.
