Change in Properties of M-10dm Mineral Motor Oil After Its Using in the Diesel Engine

The influence of the production conditions for rapeseed and soybean oils obtained by extraction in the system “solid – liquid” on the qualitative composition of the obtained vegetable oils has been studied. The main chemical values (acid value, iodine value, ester value, saponification value) and optical properties (refractometric refractive index and UV-Vis spectroscopy) for rapeseed and soybean oils obtained by extraction using methylene chloride as a solvent from different plant raw materials (grade of grinding is 0.2, 0.5 and 1.0 mm) and mixtures of crushed grain fractions have been determined. It has been shown that the grade of grinding of the raw material affects the quality of the obtained product.

“…So, the residues after vacuum distillation contain the elements that were both in the additive and in the parts of the engine. Their presence in M-10DM and NORMAL 15W40 was established earlier [10,11]. Excessive content of these metals indicates that after vacuum distillation, under the influence of temperature, thermal decomposition of additives occurs.…”

“…Previously [10,11] we studied the change in the operational properties and the group hydrocarbon composition of UMO, confirmed the formation of oxygen-containing products of oils "aging" during their long-run use in the combustion engines, and explained the change in the composition of the inorganic part of motor oils provided by the action of spent additives and falling of the engine wear parts into the oil products. The results obtained can serve as the source information for choosing the optimal recycling technology.…”

1 The physico-chemical properties and the group composition of the used mineral motor oils M-10DM and NORMAL 15W40, as well as the fractions obtained as a result of their vacuum distillation, have been studied. The results of IR spectroscopy and XRF analysis are presented. The change in the composition and properties of the fractions distilled from used oils under vacuum has been described. ЗАСТОСУВАННЯ ВАКУУМНОГО РОЗДІЛЕННЯ В ТЕХНОЛОГІЇ РЕГЕНЕРАЦІЇ ВІДПРАЦЬОВАНИХ МІНЕРАЛЬНИХ ОЛИВАнотація. Вивчено фізико-хімічні властивості та груповий склад відпрацьованих мінеральних моторних олив М-10ДМ та NORMAL 15W40, а також фракцій, одержаних в результаті їх вакуумного розділення. Наведено результати ІЧ-спектроскопічного та рентгенофлуоресцентного аналізу відпрацьованих олив та виділених фракцій. Описано зміну складу й властивостей фракцій виділених з відпрацьованих олив внаслідок їх вакуумного розділення.Ключові слова: вакуумне розділення, відпрацьована олива, ІЧ-спектроскопія, регенерація олив.

“…Previously [8] we established the optimal parameters of the thermooxidative regeneration for industrial oils, but they are not sufficient to assert that the base oil is produced as a result of UMMO regeneration. Moreover, the change in operational properties for motor oils M-10DM and NORMAL 15W40 as well as their group hydrocarbon composition were studied [9,10]. The formation of oxygen-containing products of oils "aging" was confirmed during their prolonged use in internal combustion engines and the changes in the composition of inorganic part were observed, which are explained by the action of additives and wear products of the engine.…”

The physico-chemical properties and group composition of the used mineral motor oils M-10DM and NORMAL 15W40, as well as the fractions obtained as a result of their thermooxidative regeneration have been studied. The results of IR-spectroscopic and X-ray fluorescence analysis of used oils and fractions obtained during thermooxidative regeneration are presented. The changes in the composition and properties of regenerated oils are described.
