Used motor oils (UMO) are a remarkable commodity arousing interest of each new generation of researchers. UMO also include used gear oils, but their degree of use is much lower. The primary role of motor oil is to reduce friction and prevent corrosion. It also serves to dissipate heat and hold in suspension by-products of engine wear, combustion and degradation products. Motor oil originates fr...
cf. C. A. 30, 1179.7. The fogging and bactericidal effects of the vapor from irradiated cod-liver oil and from ozonide of olive oil were found to be due to substances liberating active O. Ozonides of olive oil, emulsions of ozonide in salt soln. and in serum, and the vapor from ozonides are all germicidal. Bacteria are not only killed by the O liberated from these oils but their growth rate may...
The lubricating oils in each mechanical device are affected by shear forces. Polymers in lubricating oils engine, in particular, undergo many changes because of the influence of the applied forces. Awareness of these changes can help us to design optimal formulations. In this work, shear stability of four commercial was studied. Calculation of various parameters about viscosity in the enhancing...
The aim of the current research is to examine the potential of locally available natural clay mineral to act as an effective absorbent for waste engine oil treatment. The clay mineral was collected from the southern region of Saudi Arabia and was used without any kind of surface modification. The clay mineral was characterized by X-ray diffraction (XRD), X-ray fluorescence (XPS) and Braunner-Em...
This paper describes a laboratory method for treatment of used engine oil FENIX SUPERIOR SAE 15W-40 with intention to decrease of sulfur and selected metal content at acceptable level. FENIX SUPERIOR SAE 15W-40, produced by manufacturer Joint Stock Company FAM Krusevac, is used for lubrication of the most modern four-stroke diesel and gas engines of passenger and commercial vehicles, engine con...
