The feasibility of a variety of future diesel fuels.

在未来几十年，全球车辆将被迫减少二氧化碳排放;对于大多数轻型应用来说，部分或全部电气化似乎是实现这一目标的最可能途径。对于重型应用，特别是未来将继续增长的长途货运，电气化更具挑战性，这意味着这些操作将继续依赖内燃机和液体或气体燃料更长时间。因此，通过使用低碳燃料，无论是先进的生物燃料还是合成的电转液/气（即利用可再生能源的电子燃料）或它们的组合，可持续地使这一不断增长的运输部门脱碳，这是一个重要的机会。为了进一步增加复杂性，必须实现向低碳未来的转变，同时确保当地的空气质量和公共健康不会受到不利影响。因此，该项目将与英国石油国际有限公司合作，对一系列用于重型发动机的新型可持续低碳燃料进行实验研究。该项目将重点在专用重型压缩点火研究设施中测试代表可持续原料的模型燃料在一些实施方案中，生物质（例如木质纤维素生物质、城市固体废物、藻类和微生物）通过热化学转化技术（例如热解和水热液化）获得。此外，这将包括调查新型含氧化合物的反应性和对污染物形成的影响，例如用于改善可持续燃料混合物燃烧特性的烷基二氧戊环，以及以前未被视为重型运输的可再生燃料。原型燃料将使用一个专门修改的重型柴油研究发动机，结合一个新的低容量燃料系统，用于高压喷射目前有限的可用性或非常规物理特性的新化合物，通过进行燃烧和排放实验，分析和解释热释放和排放数据，以及排气颗粒物的潜在进一步化学表征。

Over the coming decades the global vehicle fleet will be forced to reduce its carbon dioxide emissions; for most light-duty applications it seems that partial or full electrification is the most likely route to enable this. In the case of heavy-duty applications, particularly long-distance freight which is set to continue its growth in the future, electrification is far more challenging meaning that these operations will continue to rely upon the combustion engine and a liquid or gaseous fuel for far longer. Therefore, a significant opportunity exists to sustainably de-carbonise this growing segment of transportation through the use of low-carbon fuels, either advanced biofuels or synthetic power-to-liquid/gas (i.e. e-fuels utilising renewably generated energy) or combinations of them. To add further complexity, this move to a low-carbon future must be achieved whilst ensuring that local air-quality and public health is not adversely impacted. This project will therefore aim to experimentally investigate a range of novel sustainable low-carbon fuels for heavy-duty engines, working in partnership with BP International Ltd.This project will focus on testing in a dedicated heavy-duty compression ignition research facility model fuels that are representative of those derived from sustainable feedstocks (such as lignocellulosic biomass, municipal solid waste, algae and microorganisms) obtained via thermochemical conversion technologies such as pyrolysis and hydrothermal liquefaction. In addition, this will include investigating the reactivity and impact on pollutant formation of novel oxygenated compounds, such as alkyl dioxolanes for improved combustion characteristics of sustainable fuel blends, and which have not previously been considered renewable fuels for heavy duty transportation. The prototype fuels will be investigated using a specially modified heavy-duty diesel research engine incorporating a novel low volume fuel system for high-pressure injection of novel compounds of currently limited availability or unconventional physical properties, by performing combustion and emissions experiments, analysing and interpreting heat release and emissions data, and potential further chemical characterisation of exhaust particulate matter.
