Abstract
The present study assesses the effects of ethyl octanoate and ethyl oleate on the gasoline lubricity. Samples of gasoline fuel were prepared with different amounts of esters (0%, 2.5%, 5%, 10%, and 15%) and then evaluated. The lubricity tests were carried out using a High Frequency Reciprocating Test Rig (HFRR) equipment. The Wear Scar Diameter (WSD) values decreased as ester proportions increased in the samples. The percentage of lubricant film presented values above 85% for formulations with 10% and 15% ester concentration. Coefficient of friction values showed a similar behavior, they decreased as the esters fractions have increased. Results demonstrate that the esters when added to gasoline can improve the fuel lubricity.
