Abstract

This study investigates whether very small additions of eugenol can modify the performance of a commercial RON 92 gasoline in a spark-ignition engine. Eugenol was selected as a renewable oxygenated compound because its molecular structure can influence fuel oxidation and combustion behavior. Three fuels were evaluated: unblended RON 92 gasoline (E0), gasoline containing 0.1% v/v eugenol (E0.1), and gasoline containing 0.5% v/v eugenol (E0.5). Tests were conducted on a 150 cc four-stroke motorcycle equipped with EFI and CVT and operated on a chassis dynamometer. Power and torque were recorded over the engine-speed range, and each fuel was tested in triplicate before the mean values were analyzed. Both eugenol blends outperformed the base fuel over most of the tested range. The largest peak power was obtained with E0.5, reaching 8.85 HP at 7,800 rpm, approximately 11% above E0. The highest torque, 9.78 Nm at 5,700 rpm, was produced by E0.1. The results suggest that low-dose eugenol blending can improve the conversion of fuel energy into useful engine output. Further work should examine broader blend ratios, direct combustion parameters, storage stability, and long-term engine durability.
