In this study, zinc ferrite magnetic nanoparticles (ZnFe2O4, ZFO MNPs) were employed as a sorbent for the removal of oil spill from water surfaces. ZFO MNPs were synthesized via a sol-gel process and characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray powder diffraction (XRD). Both the apparent density and magnetic force were determined. ZFO MNPs presented a considerable magnetic force (40.22 mN) and an adequate density (0.5287 g/cm3), which are important for the magnetic separation and flotation. Four oil samples (gasoline engine oil, crude oil, used motor oil and diesel engine oil) were used to investigate the gravimetric oil removal capability of ZFO MNPs. The oil sorption capacities were found to be 23.00-6.13, 27.65-7.42, 22.62-7.01 and 30.54-9.93 g/g for crude, diesel engine, gasoline engine, and used motor oil, respectively. The current findings demonstrate that ZFO MNPs exhibit good properties (e.g., magnetic and density) and can be used as a sorbent for oil spill cleaning-up from water surfaces.

The key directions of the oil aging process are closely interrelated with its fumes and this is once again confirmed by the motor experiment. The degree of oxidation of the engine oil subjected to identification by increasing the concentration of insoluble impurities identifies the thermo-oxidative destruction of the present hydrocarbons. The results of modeling the process of wear of parts of the cylinder-piston group of marine diesel are considered. Through the application of the theory of experiment planning, the range of minimum wear is revealed, the dependence is focused on the values of the quality indicators of the used fuels and lubricants, the engine boost and the amount of engine oil burn. The change in the values in the main directions of oil aging as a result of reducing its fumes was noted. There has been revealed engine oil burnout in which the operation of the diesel engine is accompanied by less carbon and varnish formation on its pistons and the wear rate of the elements of the cylinder-piston group, the engine oil being in excellent condition in terms of the composition of aging products. Oil aging rate is determined at each stage of trial, according to sample analysis. There is given the matrix of experiment planning, as well as results of its processing. There are established the equations usable in trunk diesel operation that help to analyze general and specific rate of motor oil ageing, the initial values being values of oil waste, properties of fuels and lubricants and engine forcing. Motor oil of М-14-Г2 grade (circulating system) has been recommended to use for efficient and durable operation of ship diesels with average and low boost. For high powered engines operating on deep refining fuels it is possible to use the following oil grades: М-14-Д2 (cl 20) и М-14-Д2 (cl 30) with high neutralizing and motor qualities.

Uncontrolled dumping linked to agricultural vehicles causes an increase in the incorporation of oils into the irrigation system. In this paper, we propose a system based on an optical sensor to monitor oil concentration in the irrigation ditches. Our prototype is based on the absorption and dispersion of light. As a light source, we use Light Emitting Diodes (LEDs) with different colours (white, yellow, blue, green, and red) and a photodetector as a sensing element. To test the sensor’s performance, we incorporate industrial oils used by a diesel or gasoline engine, with a concentration from 0 to 0.20 mLoil/cm2. The experiment was carried out at different water column heights, 0 to 20 cm. According to our results, the sensor can differentiate between the presence or absence of diesel engine oil with any LED. For gasoline engine oil, the sensor quantifies its concentration using the red light source; concentrations greater than 0.1 mLoil/cm2 cannot be distinguished. The data gathered using the red LED has an average absolute error of 0.003 mLoil/cm2 (relative error of 15.8%) for the worst case, 15 cm. Finally, the blue LED generates different signals in the photodetector according to the type of oil. We developed an algorithm that combines (i) the white LED, to monitor the presence of oil; (ii) the blue LED, to identify if the oil comes from a gasoline or diesel engine; and (iii) the red LED, to monitor the concentration of oil used by a gasoline engine.

Nowadays, the creation of remotely-piloted aerial vehicles for various purposes is regarded as one of the most relevant and promising trends of aircraft development. FAU "25 State Research Institute of Chemmotology of the Ministry of Defense of the Russian Federation" have studied the operation features of aircraft piston engines and developed technical requirements for motor oil for piston four-stroke UAV engines, as well as a new engine oil M-5z/20 AERO in cooperation with NPP KVALITET, LLC. Based on the complex of qualification tests, the stated operational properties of the experimental-industrial batch of M-5z/20 AERO oil are generally confirmed.

Abstract In the present study, three potentially Pb(II)-resistant and biosurfactant-producing bacterial strains were isolated from a total of 23 strains using various screening methods, investigated for their biosorption of Pb(II) and used for the biodegradation of used motor oil. The results show that strain E1 (Bacillus haynesii) has significantly high efficiency in biodegradation of used motor oil, up to 82 % in the first three days. Maximum Pb(II) biosorption capacities of 238.09 mg/g and 99.01 mg/g were determined for strains E1 and F5 (Pseudomonas aeruginosa), respectively. The biosorption process was found to be in good agreement with the Langmuir isotherm for both E1 (R2 = 0.9614) and F5 (R2 = 0.9646), suggesting monolayer biosorption. The four common screening methods, namely the haemolytic assay, the determination of surface tension, the emulsifying activity and the foam test, were also correlated with the Pearson correlation method.

In this experimental study, a four stroke diesel engine was conducted to investigate the effect of adding water-based ferrofluid to diesel fuel on engine performance. To our knowledge, Magnetic nanoparticles had not been used before. To this end, emulsified diesel fuels of 0, 0.4, and 0.8 water-based ferrofluid/Diesel ratios by volume were used as fuel. The ferrofluid used in this study was a handmade water-based ferrofluid prepared by the authors. The results show that adding water-based ferrofluid to diesel fuel has a perceptible effect on engine performance, increasing the brake thermal efficiency relatively up to 12%, and decreasing the brake specific fuel consumption relatively up to 11% as compared to diesel fuel. In addition, the results indicate that increasing ferrofluid concentration will magnify the results. Furthermore, it was found that magnetic nanoparticles can be collected at the engine exhaust using magnetic bar.
