摘要: 甲醇作为一种多种途径大规模生产的液态燃料，应用于技术成熟、热效率高的压燃式发动机，是实现交通领域深度脱碳的重要技术路径之一。然而，甲醇的理化性质与传统柴油存在显著差异，尤其是其极低的十六烷值、高汽化潜热、与柴油有限的互溶性等问题，直接应用于传统压燃式发动机面临自燃困难、特定污染物控制等一系列技术瓶颈。本文对近几年压燃式甲醇发动机的性能、燃烧、排放三个方面进行全面的梳理与综述。
Abstract: Methanol, as a liquid fuel produced on a large scale through multiple methods, is applied in mature and highly efficient compression ignition engines. It is one of the important technical paths for achieving deep decarbonization in the transportation sector. However, the physical and chemical properties of methanol differ significantly from those of traditional diesel. In particular, its extremely low cetane number, high vaporization latent heat, and limited miscibility with diesel all pose direct technical challenges when applied to traditional compression ignition engines, such as difficulties in self-ignition and control of specific pollutants. This paper comprehensively reviews and summarizes the performance, combustion, and emissions of compression ignition engines fueled with methanol in recent years.
