EVALUATION OF THE LUBRICATION OF ETHYL OLEATE AND ETHYL OCTANOATE AS GASOLINE ADDITIVE
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.
