Currently, the considerable decline in fossil fuel resources and the high rise in vehicle emissions have prompted researchers and governments to formulate strategies for sustainable energy development. In addition to imposing strict laws, promoting sustainable energy sources such as the development of new types of non-fossil fuels has been considered a suitable direction for the roadmap to healing the Earth's environment. Biomass sources have affirmed huge potentials in the production of biofuels. In the pathway of searching renewable biofuels, it is found that that 2,5-dimethylfuran (DMF) can become a promising fuel because it is synthesized from lignocellulose biomass, which is an available feedstock for the production of prospective fuels. Indeed, recent review studies have focused in great detail on engine performance evaluation using DMF but seemed to have gaps in emission characteristics. In this work, the controversial issues of emissions from spark and compression ignition engines during the DMF combustion were completely assessed. Indeed, the mechanism of formation and oxidation of DMF compounds during combustion was clearly described to serve as the basis for analyzing and comparing the pollution emission behavior of different fuels. More importantly, gaseous emissions, PM characteristics, and soot tendency from spark and compression ignition engines were thoroughly evaluated on the basis of the experimental and numerical data. In general, DMF has shown outstanding advantages upon emissions compared to fossil fuels; however, the impacts of DMF on the engine durability and fuel system should be further investigated to have a comprehensive analysis of this biofuel class.
目前，化石燃料资源的大量减少和车辆排放的增加促使研究人员和政府制定了可持续能源发展战略。除了制定严格的法律外，推广新型非化石燃料等可持续能源也被认为是地球环境修复路线图的一个合适方向。生物质资源在生物燃料生产中具有巨大的潜力。在寻找可再生生物燃料的过程中，人们发现 2,5-二甲基呋喃（DMF）可以成为一种有前途的燃料，因为它是由木质纤维素生物质合成的，而木质纤维素生物质是生产有前途燃料的可用原料。事实上，最近的综述研究详细地集中在使用 DMF 的发动机性能评估上，但似乎在排放特性方面存在差距。在这项工作中，完全评估了 DMF 燃烧过程中火花和压缩点火发动机排放的争议问题。事实上，DMF 化合物在燃烧过程中的形成和氧化机制被清楚地描述出来，作为分析和比较不同燃料污染排放行为的基础。更重要的是，根据实验和数值数据，彻底评估了火花和压缩点火发动机的气体排放、PM 特性和烟尘趋势。总的来说，与化石燃料相比，DMF 在排放方面表现出了显著的优势；然而，DMF 对发动机耐久性和燃料系统的影响仍需进一步研究，以便对这种生物燃料进行全面分析。
