Motor oil, a common lubricant. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
Motor oil, engine oil, or engine lubricant is any one of various substances used for the lubrication of internal combustion engines. They typically consist of base oils enhanced with various additives, particularly antiwear additives , detergents, dispersants , and, for multi-grade oils, viscosity index improvers .
A bottle of glycerin purchased at a pharmacy Personal lubricants commonly contain glycerol Glycerol is an ingredient in products such as hair gel Glycerol suppositories used as laxatives. Glycerol is used in medical, pharmaceutical and personal care preparations, often as a means of improving smoothness, providing lubrication, and as a humectant.
Due to the strong coupling between lubricant hydrodynamic action and the elastic deformation in contacting solids, this regime of lubrication is an example of Fluid-structure interaction. [4] The classical elastohydrodynamic theory considers Reynolds equation and the elastic deflection equation to solve for the pressure and deformation in this ...
A sample of synthetic motor oil. Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials.
