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.

To increase thermal efficiency and decrease greenhouse gas emissions, the research of fuel formulation and combustion processes for internal combustion engines has drawn attention from all across the world. The aim of the current study is divided into two subsections. The first of this section's two subsections is to thoroughly assess the impacts of physical and chemical properties of different mixtures of several gasoline octane boosters on low petroleum hydrocarbon products. Additionally, the creation of bio-gasoline fuels with high environmental octane ratings using various combinations of specific gasoline octane boosters is covered in the second of this section's two subsections. The gasoline additives included di-isobutylene (DIB), methyl tertiary butyl ether (MTBE), and isopropanol (IP). Furthermore, low petroleum gasoline fractions involved naphtha from natural gas condensate (N), light straight-run naphtha (LSRN), and hydrocracked gasoline (HG). In the current study, those renewable and sustainable gasoline additives and low petroleum hydrocarbon gasoline fractions were blended and examined as an innovative gasoline biofuel for gasoline engines for the first time. The experimental findings indicated that the octane number might be used to vary the antidetonation performance in the following order: ethanol> MTBE > Di-isobutylene > isopropanol > dimate > light straight-run naphtha > hydrocracked gasoline > naphtha from natural gas condensate > heavy straight run naphtha. Five different blends were applied and the physical and chemical characterizations of each blend separately in detail were investigated. The experimental results reported that octane numbers by research method for samples one, two, three, four, and five were 90.3, 92, 95.3, 98, and 100.2, respectively.
