Lubricant cleanliness refers to the absence of contamination. 1 Microscopic particles are the most harmful form of contamination in lubricants. They can irreversibly damage gear and bearing surfaces, shorten the service life of equipment, and cause unexpected breakdowns. 1-4 The concentration of particles in new “as supplied” drums of lubricant can differ by as much as a factor of 1,000 ...

The effects of soot-contaminated engine oil on wear and ....

AbstractDuring the diesel engine combustion process, soot particles are produced and are either exhausted into the atmosphere or absorbed by the engine's lubricant. Soot-contaminated lubricant has been shown to produce significant amounts of engine wear. The main mechanism of soot-related wear is through abrasion, but, at increased levels of soot content in the lubricant, starvation of the ...

the functions of a lubricant. Friction and abrasion between rubbing surfaces are the main factors that affect the wear in engine (Kunc et al, 1952). High friction will cause wear and surface damage because friction has a strong correlation with wear. But, high friction does not always have high wear and it’s not always direct (Fawzy, 1993).

The effect of lubricating oil condition on the friction ....

In many of the reported laboratory tests measuring piston ring and cylinder liner friction and wear, the lubricant employed is a fully formulated oil in the new condition . Obviously, the oil would not stay in that condition for very long in actual service since it will degrade with use, and will pick up both external and internal contaminants.

totally deteriorating at 7%. Wear scar diameter is found increasing with the increase of fuel contamination. In addition, the wear scar diameter depends on many factors such as load, temperature, speed and properties of the lubricant. Some oils have lower coefficient of friction but produce higher wear scars such as RBD palm olein oil.
