Abstract
Clean energy is predominant topic across several local and international conservation conferences and initiatives. The primary aim of this study is to analyze the effectiveness of octane booster in enhancing fuel quality in automotive gasoline. Research octane number (RON) refers to the octane number of fuel that influences engine performance. This octane number is determined by comparing the knock intensity with the reference fuel mixture during testing. The experimental method is the blending of octane booster and gasoline at different percentage compositions of 0.5:99.5, 1.0:99, 1.5:98.5 and 2.0: 98, respectively. These two organic substances were supplied by Pertamina, a state-owned oil and gas company in Indonesia. The blending results showed a potential increase in octane number in the fuel sample (ASTM D-2699) from 88 to 89.4, 90, 90.5 and 90.8, correspondingly. Furthermore, the effects of involving octane booster on the specific gravity, distillation, and Reid vapor pressure (RVP), as well as gum concentration were also determined. Based on the experimental and analytical data, a reasonable increase was observed in the specific gravity, distillation, and RVP for samples ASTM D-1298, ASTM D-86 and ASTM D-323, respectively. However, excessive use of octane booster has the tendency to enhance gum deposits that slightly influences the engine performance.
