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.

“…The experimental measurements of turbulent combustion are restricted by the high level of intermittency due to turbulent motion and a relatively short residence time [3,4]. Turbulent combustion can be regarded as a combination of microlaminar combustion with turbulence mass transfer, and computational models such as the flamelet model are based on this theory [5]. For the turbulent flow in a rocket chamber, the magnitude of the Taylor microscale Reynolds number Re λ is usually 10-100.…”

Compared to turbulent combustion in practical combustion devices, a co-flow laminar diffusion flame is the simplest configuration from which the interactions between flow field and reactions can be readily studied. High pressure combustion experiments on the methane/oxygen laminar co-flow diffusion flame are conducted to distinguish combustion states from 0.2 to 4 MPa. The transition combustion state between the steady state and periodical pulsation combustion state is studied quantitatively. The results obtained using a Schlieren device show that the different formation heights of the vortices generated in the jet flame shear layer lead to different combustion states. Based on the combustion pressure and Froude number at the burner exit, the upper and lower limits for the transition combustion state are proposed as Fr cr = 9.8 × 10 −4 (p r − 0.012) −1.87 ± 4.0 × 10 −5 (p r + 0.026) −2.48 , respectively. The flame is in the steady combustion state when the flame Fr is smaller than the lower limit of Fr cr. When the flame Fr is larger than the upper limit of Fr cr , pulsation combustion takes place. For the pulsation combustion state, the relationship between the Strouhal number and Froude number is established as St = 0.29 × Fr −0.65 .
