Abstract:
Octane rating is a fundamental parameter in assessing fuel quality, particularly for internal combustion engines where resistance to knocking is critical for optimal performance, efficiency, and emissions control. Higher octane numbers indicate a fuel’s greater ability to withstand premature ignition under pressure, which is essential for modern, high-compression engine designs. This poster presents the evaluation of octane performance using standardized testing protocols following ASTM D2699 for Research Octane Number (RON) and ASTM D2700 for Motor Octane Number (MON). These complementary methods provide a comprehensive understanding of a fuel’s behavior under varying operating conditions, from mild to severe. The testing system employs an engine with adjustable compression ratios, enabling accurate and repeatable octane measurements across a wide range of fuel formulations. Particular attention is given to bioethanol-gasoline blends, which demonstrate notable improvements in octane values as the proportion of bioethanol increases. This trend highlights the promise of renewable fuels not only in reducing environmental impact but also in enhancing engine performance. Standardized octane testing supports the development of advanced fuels that align with sustainability goals while meeting the performance demands of modern engines. By enabling precise characterization of combustion properties, this method can help in refining fuel formulations and guiding future innovations in the automotive and energy sectors.
