摘要: 聚甲氧基二甲醚(PODE)一种绿色的含氧燃料添加剂，在国内外的试验研究中表现出良好的燃烧与排放性能，不仅有利于改善柴油机的碳烟与NOx的“trade-off”关系，同时能消耗产能过剩的甲醇并替代柴油。本文综述了国内外耦合不同喷油参数、先进燃烧模式对燃烧及排放的影响，重点介绍了不同学者采用变PODE掺混比、负荷、喷油压力、主预喷间隔角、主喷定时、EGR率以及RCCI、HCCI等先进燃烧模式下的排放污染物影响，结果表明，柴油掺混PODE对改善碳烟排放表现出较优秀的潜力，某些特定工况下可改善NOx与Soot的“trade-off”关系。表明PODE是一种较为理想的内燃机替代燃料。
Abstract: PODE (Polyoxymethylene dimethyl ethers) is a kind of green oxygen fuel additive, its physical and chemical properties close to diesel, mixing well in diesel oil, improving the “trade-off” relationship between soot and NOx in diesel engines. In this paper, the influences of different fuel injection pa-rameters and advanced combustion modes on combustion and emission at home and abroad are summarized, with emphasis on the influences of pollutants emitted by different scholars under different PODE mixing ratio, load, fuel injection pressure, main pre-injection interval Angle, main injection timing, EGR rate, RCCI, HCCI and other advanced combustion modes. The results show that PODE has a better effect on soot emission in general, and NOx emission may decrease or increase under different conditions. The results show that PODE has a great application prospect as a diesel additive to improve emissions.
