Abstract Petroleum-derived gasoline is currently the most widely used fuel for transportation propulsion. The design and operation of gasoline fuels is governed by specific physical and chemical kinetic fuel properties. These must be thoroughly understood in order to improve sustainable gasoline fuel technologies in the face of economical, technological, and societal challenges. For this reason, surrogate mixtures are formulated to emulate the thermophysical, thermochemical, and chemical kinetic properties of the real fuel, so that fundamental experiments and predictive simulations can be conducted. Early studies on gasoline combustion typically adopted single component or binary mixtures (n-heptane/isooctane) as surrogates. However, the last decade has seen rapid progress in the formulation and utilization of ternary mixtures (n-heptane/isooctane/toluene), as well as multicomponent mixtures that span the entire carbon number range of gasoline fuels (C 4 –C 10 ). The increased use of oxygenated fuels (ethanol, butanol, MTBE, etc.) as blending components/additives has also motivated studies on their addition to gasoline fuels. This comprehensive review presents the available experimental and chemical kinetic studies which have been performed to better understand the combustion properties of gasoline fuels and their surrogates. Focus is on the development and use of surrogate fuels that emulate real fuel properties governing the design and operation of engines. A detailed analysis is presented for the various classes of compounds used in formulating gasoline surrogate fuels, including n-paraffins, isoparaffins, olefins, naphthenes, and aromatics. Chemical kinetic models for individual molecules and mixtures of molecules to emulate gasoline surrogate fuels are presented. Despite the recent progress in gasoline surrogate fuel combustion research, there are still major gaps remaining; these are critically discussed, as well as their implications on fuel formulation and engine design.

汽油替代燃料的最新进展

摘要 石油衍生汽油是目前应用最广泛的交通推进燃料。汽油燃料的设计和操作由特定的物理和化学动力燃料特性决定。必须彻底了解这些,以便在面临经济、技术和社会挑战时改进可持续汽油燃料技术。出于这个原因,替代混合物被配制为模拟真实燃料的热物理、热化学和化学动力学特性,以便可以进行基础实验和预测模拟。早期的汽油燃烧研究通常采用单组分或二元混合物(正庚烷/异辛烷)作为替代物。然而,在过去十年中,三元混合物(正庚烷/异辛烷/甲苯)以及跨越汽油燃料整个碳数范围(C 4 -C 10 )的多组分混合物的配制和利用取得了快速进展。越来越多地使用含氧燃料(乙醇、丁醇、MTBE 等)作为混合组分/添加剂也促进了对它们添加到汽油燃料中的研究。这篇综合评论介绍了现有的实验和化学动力学研究,这些研究旨在更好地了解汽油燃料及其替代品的燃烧特性。重点是开发和使用替代燃料,模拟控制发动机设计和运行的真实燃料特性。对用于配制汽油替代燃料的各类化合物进行了详细分析,包括正链烷烃、异链烷烃、烯烃、环烷烃和芳烃。介绍了模拟汽油替代燃料的单个分子和分子混合物的化学动力学模型。尽管汽油替代燃料燃烧研究最近取得了进展,但仍然存在重大差距;这些都得到了批判性的讨论,以及它们对燃料配方和发动机设计的影响。
