Material‐Dependent Antagonistic Effects between Soot and ZDDP
Advanced Materials Interfaces, 2020 AbstractWhile soot in engine oil is known to accelerate the wear of diesel and gasoline direct‐injection compression‐ignition engines, there is a lack of consensus on the wear mechanism though various hypotheses have been proposed in the literature. Particularly, some recently observed antagonistic effects between soot and a common lubricant antiwear ...
