Ability to withstand temperatures without decomposing. Not to be confused with oxidation stability where oxygen must be present and oxidation rather than decomposition.
The metallic soap or other material used to combine with oil or other lubricating fluid to make a grease.
Measure of the extreme pressure properties of a lubricant. Lubricated by the product under investigation, a standard steel roller rotates against a block. Timken OK load is the heaviest load that can be carried without scoring.
The twisting force with which the engines crankshaft actually rotates, measured in foot-pounds.
The quantity of base, expressed in milligrams, that is required to neutralize all acidic constituents present in one gram of sample.
The quantity of acid, expressed in terms of the number of milligrams that is required to neutralize all basic constituents present in one-gram sample.
The total amount of solids contamination, both suspended and non-suspended present in the lubricant. This test is indicative of carburetion problems (too rich or too lean), if the oil filter has reached the saturation point and is no longer able to remove
Science of the interactions between surfaces moving relative to each other, including the study of lubrication, friction and wear.
A device consisting of blades attached to a disc or rotor, which converts flow into rotary action.
A device for increasing the pressure and hence the mass of air and fuel burned on each firing stroke. A turbine of exhaust gases drives a compressor; therefore, efficiency is variable and related to exhaust pressure.
