During engine operation, lubricating oil accumulates not only insoluble contaminants, but also soluble products of aging such as "resins" and also heavier substances that cannot be desorbed from silica gel by alcohol- benzene or acetone—benzene mixtures. The relative content of hydrocarbon groups is...
CHEMICAL COMPOSITION OF USED MOTOR OILS V, A. Litvishkova, A. I. Bukhter, A. V Nepogod'ev, and A. M. Bezhanidze UDC 665.521.5 Changes in oil composition during engine operation are caused by the accumulation of solid contaminants and by chemical conversion of the additives and the ...
Role of silicon on the tribological performance of Al-based automotive alloys and the effect of used motor oil A wear test in a used motor oil sliding environment was performed on Al-based automotive alloys with Silicon doped in various levels. Where a pin-on-disc w... S Kaiser,A Khan ...
The available information shows that used motor oil is a very dangerous polluting product. As a consequence of its chemical composition, world-wide dispersion and effects on the environment, used motor oil must be considered a serious environmental problem. 展开 关键词:...
Limited studies in the literature have assessed the chemical composition of automotive lubricating oils; however, many of these papers are dated and new oil manufacturing technologies, including the use of new additives, combined with different engine types and operations will result in the production ...
Motor oil classification by base stock is important for quality control and identification of oil adulteration. Type of motor oil base stock is a key factor in product price formation. The difference in chemical composition of “synthetic” (polyalphaolefins (PAOs) or Group III base oils) and...
Uses include transfer of mud and liquids, both on the surface and downhole as in pumping crude oil or water from the reservoir to the surface. Interestingly, drillers discovered decades ago that if pressurized fluid (such as a drilling mud or water) is pumped into the pump, the progressive...
An ADF is a fee imposed on a product, such as tires, motor oil, white goods, batteries, and containers, which is intended to reflect its cost of disposal. From: Solid Waste Recycling and Processing (Second Edition), 2014 About this pageSet alert ...
Motor fuels are produced from oil and gaseous hydrocarbons. They are among the main products of petroleum processing, accounting for about 63 percent of the consumption of petroleum products. A motor fuel usually consists of mixtures of several components, including the base fuel and additives (anti...
Known methods for directly determining the degree of motor oil degradation or contamination include, for example, measuring the electrical resistance of the oil the pressure differential between upstream and downstream sides of the oil filter, transparency, or chemical composition of the motor oil. The...
