Decarbonising the transport sector is a top priority worldwide. The difficult-to-decarbonise transport applications (including mainly shipping, road freight and aviation) emit more than 50% CO2 of the entire transport sector. Among efforts on developing low-emission fuels, liquid synthetic fuels that can massively reduce pollutant emissions are drawing increasing attention, as they can be integrated into the current transportation system using existing infrastructure and combusted in existing engines (such as diesel engines for optimal fuel economy) with minor adjustments as drop-in fuels. Liquid synthetic fuels such as oxymethylene ethers (OMEx, which possess liquid properties similar to diesel when x=3-5) can be produced from a range of waste feedstocks and biomass, thereby avoiding new fossil carbon from entering the supply chain. OMEx can also be produced as an electrofuel (or e-fuel), thereby used as a sustainable energy carrier. However, due to the lack of complete knowledge of the physicochemical properties associated with the fuel composition variability, i.e. variation in the oligomer length (the x value of OMEx) and the composition variation of OMEx-diesel blends in real engine environment, there are challenges in utilising OMEx in practical engines, mainly in engine and its operation adjustments for optimal performance and minimal pollutant emissions. To address the technical issues of OMEx utilisation, accurate information on physicochemical properties and pollutant emissions of the synthetic fuels over the engine operational ranges is mandatory, but this is not readily available.This project is intended to obtain a thorough understanding on liquid synthetic fuel utilisation. The project will address the fundamental challenges in utilising renewable synthetic fuels, in particular OMEx and the associated OMEx-diesel fuel blends. The study will follow a combined modelling / simulation - experimentation approach, predicting the physicochemical properties including emission characteristics of the alternative fuels using molecular dynamics simulations, tailor-made experimentation for first-hand information on fuel utilisation, and establishing a database / mapping to guide the synthetic fuel utilisation in real engines over a wide range of conditions using machine learning.

运输部门的脱碳是全球的首要任务。难以脱碳的运输应用（主要包括航运、公路货运和航空）排放的二氧化碳占整个运输部门的50%以上。在开发低排放燃料的努力中，可以大规模减少污染物排放的液体合成燃料正引起越来越多的关注，因为它们可以使用现有的基础设施集成到当前的运输系统中，并在现有的发动机中燃烧（例如柴油发动机，以实现最佳的燃料经济性），并进行微小的调整。液态合成燃料如甲醛醚（OMEx，当x=3-5时，其具有类似于柴油的液体性质）可以由一系列废物原料和生物质生产，从而避免新的化石碳进入供应链。OMEx也可以作为电燃料（或电子燃料）生产，从而用作可持续能源载体。然而，由于缺乏对与燃料组成可变性（即低聚物长度（OMEx的x值）的变化）和真实的发动机环境中OMEx-柴油共混物的组成变化相关的物理化学性质的完整知识，因此在实际发动机中利用OMEx存在挑战，主要是在发动机及其操作调整中，以实现最佳性能和最小污染物排放。为了解决OMEx利用的技术问题，必须提供关于合成燃料在发动机工作范围内的物理化学性质和污染物排放的准确信息，但这并不容易获得。本项目旨在全面了解液体合成燃料的利用。该项目将解决利用可再生合成燃料的根本挑战，特别是OMEx和相关的OMEx-柴油混合燃料。该研究将采用建模/模拟-实验相结合的方法，使用分子动力学模拟预测替代燃料的物理化学性质，包括排放特性，为燃料利用的第一手信息量身定制实验，并建立数据库/映射，以指导使用机器学习的真实的发动机在各种条件下使用合成燃料。
