Comparison between citronella oil and clove oil additives on fuel consumption, power and torque of motorcycle

The use of essential oil additives in petrol has been widely recognised to improve fuel quality because it can increase the oxygen content, which improves combustion performance in the combustion chamber. This study aims to analyse the effect of adding citronella oil and clove oil as essential oil additives into petrol fuel on fuel consumption, power and torque of motorcycles. This research was conducted through an experimental study by varying the composition of additives added to petrol fuel. Citronella and clove oil were added to petrol fuel of RON 90 in ratios of 5%, 10%, and 15%. The results confirmed that adding citronella oil could improve combustion performance better than adding clove oil. Among these ratios, the addition of 10% citronella oil gave the most significant improvement to the combustion performance of the motorcycle in all criteria: fuel consumption, power and torque.
