Введение. В процессе сгорания дизельного топлива в дизельном двигателе при повышенной подаче топлива в результате его неполного сгорания образуются частицы сажи, которые либо выбрасываются в атмосферу, либо попадают в моторное масло. Сажа, загрязняя моторное масло, вызывает изменение его показателей качества. Сажа представляет собой очень мелкие частицы, образующиеся по сложному механизму реакции в пламени богатой топливом области при сжигании углеводородов в отсутствие воздуха, в основном состоящие из смеси аморфного углерода и органического вещества.

Материалы и методы

Материалы и методы. В данной работе приведены результаты литературного обзора, направленного на изучение путей возникновения сажи при эксплуатации дизельных двигателей , ее влияния на поверхности пар трения и узлов двигателя, также обсуждаются механические свойства дизельной сажи. Выводы. Содержание сажи в моторном масле резко возрастет в двигателях с рециркуляцией отработавших газов, что приводит к повышению температуры в зонах трения и вязкости смазочного материала, а также к образованию отложений на горячих деталях. Эти процессы происходят по причине разряжения в картерном пространстве и интенсификации поступления газов из камеры сгорания. Интервалы замены масла необходимо контролировать при повышенной интенсивности поступления сажи в моторное масло.

Рамки исследования/возможности. Такого вида исследование поможет определить причины возникновения сажи в дизельном двигателе, понять последствия использования загрязненного частицами сажи моторного масла.

Оригинальность/ценность

Оригинальность/ценность. Проведенное исследование может являться основой для разработки рекомендаций по совершенствованию технического обслуживания двигателей внутреннего сгорания для предприятий, имеющих в своем распоряжении автомобили с дизельными двигателями с целью увеличения ресурса силовых агрегатов и сокращения эксплуатационных затрат.

Introduction

Introduction. During the combustion of diesel fuel in a diesel engine with an increased fuel supply, as a result of its incomplete combustion, soot particles are formed, which are either released into the atmosphere or inevitably enter the engine oil. Soot, polluting the engine oil, causes a change in its quality indicators. Soot is very small particles formed by a complex reaction mechanism in the flame of a fuel-rich region during the combustion of hydrocarbons in the absence of air, mainly consisting of a mixture of amorphous carbon and organic matter.

Materials and methods

Materials and methods. This paper presents the results of a literary review aimed at studying the ways of soot occurrence during the operation of diesel engines, its effect. The mechanical properties of diesel soot are also discussed on the surfaces of friction pairs and engine components.

Conclusions

Conclusions. The soot content in engine oil will increase sharply in engines with exhaust gas recirculation, which leads to an increase in temperature in the friction zones and viscosity of the lubricant, as well as to the formation of deposits on hot parts. These processes occur due to the discharge in the crankcase space and the intensification of the intake of gases from the combustion chamber. Oil change intervals should be monitored at an increased rate of soot entering the engine oil.

Scope of the study / opportunity. This type of study will help determine the causes of soot in a diesel engine, understand the consequences of using engine oil contaminated with soot particles.

Originality / value

Originality / value. The conducted research can be the basis for the development of recommendations for improving the maintenance of internal combustion engines for enterprises that have cars with diesel engines at their disposal in order to increase the resource of power units and reduce operating costs.
