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.

Abstract This study shows the application of pyrolytic oil derived from Waste Engine oil (WEOPO) as an alternative fuel by blending with Ethanol. For this, the effect of blending of ethanol at 5 %, 10 %, 15 %, 20 %, 25 %, and 30 % on the compositions and fuel properties were analyzed. The utmost blending was established based on the higher heating value. The pyrolytic oil used for this study was produced at 550 °C which was the optimum pyrolytic temperature. A comparison study of the blended oil was done with commercially available gasoline to observe the similarities in their fuel properties and composition. The study confirmed that ethanol can be blended with WEOPO at 20% by volume to obtain a fuel of a higher heating value of about 44.24 MJ/kg that can be used as fuel. Since, WEOPO contains 65.80% of C4-C12 (gasoline range) hydrocarbon compounds and the rest 31.48 % C11–C15, 11.84 % C15-C19, and 6.94 % >C19 compounds it can be used as a future fuel.

Hydrophobic Material

A very low-density oil-absorbing hydrophobic material was fabricated from cellulose nanofiber aerogels–coated silane substances. Nanocellulose aerogels (NCA) superabsorbents were prepared by freeze drying cellulose nanofibril dispersions at 0.2%, 0.5%, 0.8%, 1.0%, and 1.5% w/w. The NCA were hydrophobically modified with methyltrimethoxysilane. The surface morphology and wettability were characterized by scanning electron microscopy and static contact angle. The aerogels displayed an ultralow density (2.0–16.7 mg·cm-3), high porosity (99.9%–98.9%), and superhydrophobicity as evidenced by the contact angle of ~150° that enabled the aerogels to effectively absorb oil from an oil/water mixture. The absorption capacities of hydrophobic nanocellulose aerogels for waste engine oil and olive oil could be up to 140 g·g-1 and 179.1 g·g-1, respectively.
