The study aims to substantiate the parameters and operating mode of the oil purification device from oxidation products to improve the efficiency of the use of lubricants. The methods of mathematical analysis and mathematical statistics, comparative comparison, generalization, and testing methods of agricultural machinery are used in the research process. It is established that engine oils are intensively polluted by oxidation products during processing, thereby accelerating the friction process due to the overload of tractor engines. During the performance of agricultural work in the oil composition, the content of oxidation products in the form of carbon, carbon dioxide, and asphalt products increases by 1.2%. Analytical coupling dependences for the process of cleaning motor oils from oxidizing products are obtained, and the dependence of the cleaning efficiency on the device parameters is established. The developed device consists of a container for collecting oils, a steam generator, a container for a sump mixer, a separate container for pure and sedimentary oils, and a vessel for re-collecting acetone. An installation has been developed to implement the technology of collecting and renewing oils in the conditions of the farm. In this case, the amount of contamination and the composition of oils is determined, and the operating mode of the device is selected for their resumption.

The article presents, developed operating modes and substantiates the parameters of a device that cleans motor oils from oxidation products and the resulting analytical relationships representing the movement of a mixture of acetone and used motor oil in viscosity states and the process of evaporation of the solvent from the oil during processing. It also substantiates the speed of movement of motor oil on a coneshaped surface based on its effect on refining and substantiates the dependence of the quality of refined oil on the temperature indicator of the mixture and the availability of the evaporation process and it was also found that motor oils are intensively contaminated with oxidation products during processing, thereby accelerating the friction process. During agricultural work, tractor engines due to congestion and oxidation of carbon, the content of carbine, carbide and asphalt products increases by 1.2%. Oxidizing products accelerate the deterioration of the quality of oils, which leads to an increase in the power consumption of the engine KShM and CPG by 15%. In addition, analytical relationships were obtained representing the movement of a mixture of acetone and used motor oil in viscosity states and the process of evaporation of the solvent from the oil during processing. The speed of motor oil on a cone-shaped surface is substantiated based on its effect on refining, and the dependence of the quality of refined oil on the temperature of the mixture and the availability of the evaporation process is justified

    The accreditation of a fast, inexpensive, and simple way to discriminate between different kinds of oils and their efficacy “degree of consumption (DoC)” has been developed. The fluorescence spectroscopy provides a reliable method for oil inspection without resorting to tedious separation. Different new and used oil samples available in the local Iraqi market were investigated. While the challenge is to build a directory containing data of all the oils available in the local market. This method expected to control the falsified (forged) trademarks of motor oils and to discriminate between different oils. The excitation-emission spectra of oil samples were determined in the range of 200 – 600 nm. The effect of the presence of trace metals on the fluorescence intensity of oils was considered by adding few milligrams of (Cu, Al, Fe) to the diluted oil solution. No major effect noticed on fluorescence intensity. The research suggests installing a simple Spectrofluorometer into vehicles to check the DoC of the oil regularly and to notify the driver exactly when to replace the engine oil. The obtained results indicate the applicability to execute such gadget to be installed in the vehicles for routine detection of the engine oil quality and its degree of consumption DoC. As well as demonstrate the potential of the technique in oil identification and could be further developed.

The work of traditional cyclones is based on the separation of solid particles using only the centrifugal forces. Therefore, they do not demonstrate high gas-cleaning efficiency, particularly in the cases where gas flows are polluted with fine solid particles (about 20 µm in diameter). The key feature of a new-generation multi-channel cyclone separator’s structure is that its symmetrical upgraded curved elements, with openings cut with their plates bent outwards, make channels for the continuous movement of the gas flows from the inflow opening to the central axis. The smoke flue of the vertical gas outflow is located near the cover of the separating chamber. The present work is aimed at studying the applicability of two various viscosity models and their modified versions to simulate aerodynamic processes in an innovative design for a multi-channel cyclone separator with a single inflow, using the computational fluid dynamics. The research results obtained in the numerical simulation are compared to the experimental results obtained using a physical model. The main purpose of this study is to provide information on how the new design for the multi-channel cyclone affects the distribution of gas flow in the cyclone’s channels. The modified viscosity models, k-ε and k-ω, and computational meshes with various levels of detailed elaboration were analyzed. The developed numerical models of a single-inlet multi-channel cyclone separator allow the researchers to describe its advantages and possible methods of improving its new structure. The developed models can be used for simulating the fluid cleaning phenomenon in the improved fourth-channel cyclone separator and to optimize the whole research process.

Abstract Seeds kept in long-term storage are essential for maintaining genetic resources of crops and other plant materials in seed banks and national germplasm systems. But seeds undergo chemical changes over time as part of the ageing process that result in reduced germination rates and seedling normalcy. For example, oilseed crops such as peanuts are particularly vulnerable to oxidation and rancidification due to their high oil content. To test the effect of storage time on seed oil in peanuts, we grew different accessions and harvested fresh seeds to compare the oil composition of new seeds with seeds aged in storage for varying lengths of time. Out of the nine fatty acids detected and measured by gas chromatography, five including oleic, gadoleic, behenic, lignoceric and cerotic acids differed significantly between new and old seeds. Additionally, old seeds accumulated up to four oxidation products together averaging about 1% of the total oil composition. The concentration of these oxidation products was positively correlated with the age of the seeds, increasing linearly up to more than 6% of the total in the oldest seeds. The presence and concentration of oxidation products measured using simple chromatography techniques can be used as an initial indication of quality and viability in older seed inventories stored in germplasm repositories.

The article considers the current methods of calculating norms of lubricating oil consumption by marine diesels that provide for three causes of oil loss: oil burning, evaporation rate, and replacement expense. According to the manual, the lubricating oil consumption for replacement is considered only in trunk diesel engines; in main crosshead diesel engines with capacity over 3000 kW it is not considered and not performed. The lubricating oil consumption norms are proposed to carry out in terms of burnout and evaporation, according to the methods of determining fuel consumption norms. To determine consumption norms, it is necessary to know the oil consumption characteristic in relation to the load of the diesels and the load distribution in the ship operating mode. In the low speed crosshead diesel engines the circulating oil is only consumed for evaporation, but the trunk diesel engines consume oil for evaporation, burnout and replacement. The diagram of dependence of the relative cylinder oil consumption on the relative load of the diesel engine in the helical characteristic mode is illustrated. A simplified technological scheme of low-tonnage regeneration of the used motor oils is presented. It is proposed to calculate the oil consumption by the lubrication pump according to a nonlinear dependence based on the speed of the crankshaft at a specific mode. The analysis of the evaporation and burnout is recommended to carry out using a linear relationship, subject to oil consumption in the idle mode. The cost of circulating oil replacement is recommended to calculate according to the diesel operating time. Application of the used lubricating oil regeneration by means of a ship small-sized plant allows to achieve the oil consumption reduction by 19-48% depending on the ship operating mo
