The combustion of conventional fuels within the transportation sector is a crucial driver of global warming and produces a number of harmful emissions. To decrease these adverse factors, the development of synthetic fuels produced from renewable energy sources via the catalytic conversion of carbon dioxide (CO2) and hydrogen (H2) has progressed significantly. Eco-friendly fuels have a reduced impact on the environment throughout their production and use cycles. In recent years, the use of polyoxymethylene dimethyl ethers (PODEn) as fuels has received an increasing amount of attention, owing to their engine performance and reduced environmental impact. The specific target of this paper is to systematically review the field of PODEn application-based additives as fuel for internal combustion engines. The background and highlights of current and future applications of PODEn are also discussed, and the challenges associated with the use of this additive are also briefly reviewed. A number of studies have shown that the use of fuel mixtures with up to 10% PODE3-4 can have a significant impact on the reduction of engine emissions. PODEn have been shown to reduce the emissions of soot, particulates, CO, and HC under different parameters and working conditions, although NOx and brake-specific fuel consumption (BSFC) emissions have been found to increase. Additionally, PODEn can be produced from natural gas or electric power via CO2 activation in a sustainable manner, which represents a significant benefit with regard to the use of oil-based products. Finally, fossil fuels blended with PODEn can be easily ignited and burned at stoichiometric conditions.

聚甲醛二甲醚添加剂作为内燃机的环保燃料概述：当前的应用和环境影响。
运输部门中常规燃料的燃烧是全球变暖的关键驱动力，并产生许多有害排放物。为了减少这些不利因素，通过可再生能源通过二氧化碳（CO2）和氢气（H2）的催化转化生产合成燃料的工作取得了显着进展。环保燃料在整个生产和使用周期中对环境的影响均减小。近年来，由于它们的发动机性能和减少的环境影响，使用聚甲醛二甲醚（PODEn）作为燃料已引起越来越多的关注。本文的具体目标是系统地回顾基于PODEn应用的添加剂作为内燃机燃料的领域。还讨论了PODEn当前和未来应用的背景和重点，并简要回顾了与使用这种添加剂相关的挑战。大量研究表明，使用PODE3-4含量不超过10％的混合燃料可对减少发动机排放产生重大影响。尽管发现NOx和特定于制动器的燃料消耗（BSFC）排放增加，但PODEn在不同的参数和工作条件下可减少烟灰，微粒，CO和HC的排放。另外，PODEn可以可持续方式由天然气或电力通过CO2活化生产，这在使用油基产品方面具有显着优势。最后，
