Advanced Progress and Prospects for Producing High-Octane Gasoline Fuel toward Market Development: State-of-the-Art and Outlook

Abstract

The development of oil refining in advanced nations is mostly focused on low-carbon fuel. Similar efforts are being made to improve the fuel efficiency of internal combustion engines, which will result in lower exhaust emissions. Furthermore, by assessing the indicated trends in engine building, it is important for fuel manufacturers to understand how the requirements for gasoline quality indicators will change, primarily for its knock resistance. The aim of the current comprehensive article is to study the state-of-the-art review emphasizing recent progress and prospects for producing high-octane gasoline fuel toward market development. The market for branded gasoline and multifunctional additives, involving friction modifiers, corrosion inhibitor components, as well as detergent components is presented. Furthermore, market development trends and quality requirements for motor gasoline, involving antiknocking characteristics and gasoline oxygenated compounds as additives, are exhibited. Besides, perspective gasoline engine technologies, including different types of engines, are declared. The formulation of effective gasoline surrogates is a challenging task due to advanced combustion strategies, engine design, and variable operating conditions in spark-ignition engines. The extensive development of direct injection and turbocharging technologies is constrained by the actual compression ratio of engines. Likewise, an increase in the knock resistance of the produced gasoline would further increase the compression ratio and efficiency of new internal combustion engines. © 2023 American Chemical Society.
