PROPERTIES OF SELECTED DERIVATIVES OF HYDROXYAMINES AND SUCCINIC ACID ANHYDRIDE AS ANTI-WEAR ADDITIVES FOR LOW-SULPHUR GASOLINES
Journal Title: Tribologia - Year 2010, Vol 229, Issue 1
Abstract
The issue of gasoline lubricity is related to the increase of popularity of direct gasoline injection engines and reduction of sulphur content in these fuels. Modern gasolines have low lubricity which can be improved by the use of anti-wear additives. In this work the influence of additives synthesized from alkenyl derivative of succinic acid anhydride and selected hydroxyamine on the lubricity of commercially available Eurosuper 95 gasoline was studied. Modified high frequency reciprocating rig (HFRR) tester was employed in this study. Some of synthesized additives introduced into Eurosuper 95 gasoline in 50 ppm concentration significantly improved its lubricity, which was demonstrated by reduction of corrected wear scar diameter from 831 μm for base fuel to values lower than 450 μm, which was accompanied by reduction of friction coefficient from μ = 0.93 to μ = 0.31–0.33.<br/><br/>
