The role of citronella oil as a bio-additive on laminar burning characteristics of iso-octane

Year: 2026

Type: article

Abstract: This study focuses on the laminar burning velocity of iso-octane fuel with a citronella additive. The main objective is to investigate and synthesize the composition of citronella bio-additive in iso-octane fuel and how it affects laminar burning velocity. Laminar burning velocity testing was conducted in a cylindrical explosion combustion chamber at constant pressure with six compositions (IC-0 to IC-5) at equivalence ratios (ɸ) of 0.8 to 1.2. Functional groups were examined by Fourier Transform InfraRed (FTIR) and volatility was characterized by Thermogravimetric Analysis (TGA). The IC-2 mixture increased the Research Octane Number from 92.0 to 92.3; whereas, the smallest decrease in laminar burning velocity was 4.8% compared to IC-0. TGA testing showed an increase in volatility in IC-2. Overall, the addition of low dose citronella bio-additives, especially IC-2, provided a moderate octane increase with a minimal reduction in laminar burning velocity and improved evaporation, supporting its potential as a practical bio-additive for spark ignition fuels.
