Abstract
The use of essential oil additives in fuel has been widely recognized to enhance fuel quality due to increasing oxygen content. The increased oxygen content in the fuel can improve combustion performance in the combustion chamber. This study aims to analyze the effect of citronella oil and clove oil as essential oil additives to gasoline on fuel consumption, power, and torque of motorcycles. This research is conducted through the experimental study by varying the composition of additives added to gasoline. Citronella and clove oil are added to RON 90 gasoline in a 5%, 10%, and 15% ratio. The result confirms that adding citronella oil can improve combustion performance than clove oil. Among those ratios, citronella oil 10% makes the most significant improvement on the combustion performance of motorcycles on all criteria: fuel consumption, power, and torque.
