Description

<p>Technology trend on boundary lubrication additives as like as anti-wear agents and friction modifiers for automotive engine oil application is summarized. ZnDTP has been still main additive in automotive engine oil formulation as cost effective one providing both wear protection and oxidation inhibition. Phosphorus content in motorcycle engine oil will be reduced to cope with future tighter exhaust emission regulation as same as passenger car engine oil. Newly developed organic friction modifiers showed superior fuel economy improvement performance for passenger car gasoline engine oil compared with exiting FMs. MoDTC application in heavy duty diesel engine oil maybe gradually proceeding because soot contamination into engine oil have been reducing in recent heavy duty diesel engine to meet emission regulation.</p>
