ABSTRACTProposal Number: CTS-0535791Principal Investigator: Ashford, MarcusAffiliation: University of AlabamaProposal Title: SGER: Volatility Correlations in Blended Hydrocarbon FuelsThe proposal was received as an unsolicited submission to the Chemical and Transport Systems Division in the Small Grants for Exploratory Research (SGER) category and was subsequently funded by the Thermal Transport and Thermal Processing Sub-element of the Thermal Systems Program. The goal of project is to establish correlations between the boiling characteristics (in contact with a surface) of a gasoline-like fuel and that fuel's volatility. Volatility describes how much of a fuel will vaporize at a given temperature and pressure. The environmental implications of this research are considerable: hydrocarbon fuels are a major global energy source. The transportation sector alone produces almost half of nationwide emissions of volatile organic compounds (VOC), hydrocarbons that include carcinogens, acute toxins and precursors to smog formation. Automobiles and light trucks depend almost exclusively on combustion engine powerplants that consume liquid hydrocarbon blended fuels, which must be vaporized prior to combustion. Fueling imprecision caused by improper prediction of fuel vaporization is responsible for virtually all tailpipe VOC emissions from automobile engines. This research will lead to more intimate knowledge of the fuel's vaporization characteristics, facilitating precise fueling and significant emissions reductions.

摘要提案编号：CTS-0535791主要研究者：阿什福德、马库斯所属单位：阿拉巴马大学提案标题：SGER：混合烃燃料中的挥发性相关性该提案是作为探索性研究（SGER）小赠款类别中化学和运输系统分部的主动提交文件收到的，随后由热系统计划的热运输和热处理子要素提供资金。 该项目的目标是建立类似汽油的燃料的沸腾特性（与表面接触）和燃料的挥发性之间的相关性。挥发性描述了在给定的温度和压力下有多少燃料会蒸发。这项研究的环境影响是相当大的：碳氢化合物燃料是一种主要的全球能源。仅运输部门就产生了全国挥发性有机化合物（VOC）排放量的近一半，这些化合物包括致癌物，急性毒素和烟雾形成的前体。汽车和轻型卡车几乎完全依赖于燃烧发动机动力装置，这些发动机动力装置消耗液态烃混合燃料，这些燃料必须在燃烧之前蒸发。由于对燃油蒸发的不正确预测而引起的供油不精确是造成汽车发动机排气管VOC排放的主要原因。这项研究将导致更深入地了解燃料的蒸发特性，促进精确加油和显著减少排放。
