Effect of lubricant additives on the prowear characteristics of synthetic diesel soots

Conference ·
OSTI ID:6364972

Soot in the crankcase of diesel engines promotes wear. The theory is that this soot preferentially adsorbs the active antiwear species, probably a zinc dithiophosphate (ZDP) decomposition product, before the protective antiwear surface coating can be formed on the rubbing surfaces. Previous studies indicated that the prowear characteristics of diesel soot depend on the engine operating conditions and the lubricant used. This observation suggested that, by properly formulating the oil, the adverse effects of the soot might be minimized.
