Так как техническое обслуживание современных двигателей часто сводится к замене моторного масла, то увеличение продолжительности его работы значительно сокращает эксплуатационные затраты и простои в техническом обслуживании. Длительная безремонтная эксплуатация двигателей внутреннего сгорания автомобильной техники непосредственно связана с состоянием моторного масла, применяемого в данном силовом агрегате. Основной причиной написания работы явилась необходимость показать особенности эксплуатации техники при значительных интервалах замены моторных масел с целью повышения эффективности её использования. В работе приведены данные об особенностях эксплуатации техники при использовании высококачественных моторных масел с увеличенными интервалами замены.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Эксплуатационные испытания проводились на базе автомобилей Mercedes-Benz Axor, Mercedes-Benz Actros. Завод-изготовитель предоставил оценочные показатели работоспособности моторных масел для двигателей. Основные характеристики работоспособности моторных масел оценивались стандартными методами: кинематическая вязкость измерялась при помощи вискозиметра Штабенгера, щелочное число определялось автоматическим титратором АТ-500, содержание продуктов износа было получено эмиссионным спектрофотометром со связанной плазмой ASP.</p></sec><sec><title>Результаты</title><p>Результаты. Представлены данные о зависимости изменения основных показателей работоспособности моторных масел от наработки, а также обоснованы требования к объёмам доливаемых свежих моторных масел для восполнения потерь.</p></sec><sec><title>Обсуждение и заключение</title><p>Обсуждение и заключение. Промежуточный контроль, описываемый в статье, позволяет выявить неисправности двигателей внутреннего сгорания автомобиля, а также дать наиболее точный прогноз о ресурсе рассматриваемого смазочного материала. Увеличение интервалов замены моторного масла позволяет получить значительный экономический эффект.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The effective operation of cars largely depends on the state of the engines, their downtime in maintenance and repair. Since the maintenance of modern engines is often reduced to the replacement of engine oil, the increase in the duration of its work significantly reduces maintenance costs and downtime in maintenance. Long maintenance-free operation of the internal combustion engines of automotive vehicles is directly related to the state of the engine oil used in this power unit. The aim of the paper is to show the features of the equipment operation with significant intervals of the engine oils’ replacement in order to increase the efficiency of its usage. The paper presents data on the features of the equipment operation when using high-quality motor oils with extended replacement intervals.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The authors conducted performance tests on the basis of MercedesBenzAxor, MercedesBenzActros cars. The manufacturer provided an estimate of the performance of engine oils. The main performance characteristics of motor oils were assessed using standard methods: kinematic viscosity was measured using a Stabinger viscosimeter, the base number was determined by an automatic AT-500 titrator, the content of wear products was obtained using an ASP-coupled emission spectrophotometer.</p></sec><sec><title>Results</title><p>Results. As a result, the authors presented data on the dependence of the changes in the main indicators of engine oil performance while the operating time and also substantiated the requirements for the volumes of fresh engine oil to compensate losses.</p><p>Discussion and conclusions. The intermediate control allows detecting faults in the internal car engines, as well as providing the most accurate prediction of the resource of the lubricant under consideration. Therefore, the increasing of the engine oil change interval allows getting a significant economic effect.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>моторные масла</kwd><kwd>смазочные материалы</kwd><kwd>кинематическая вязкость</kwd><kwd>кислотное число</kwd><kwd>щелочное число</kwd><kwd>двигатель внутреннего сгорания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>motor oils</kwd><kwd>lubricants</kwd><kwd>kinematic viscosity</kwd><kwd>acid number</kwd><kwd>base number</kwd><kwd>internal combustion engine</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">.
