摘要
回顾了直喷式柴油机燃用清洁代用燃料二甲醚(DME)的燃烧与污染物生成机理的研究情况。结合DME高温热解、高温氧化以及低温自燃着火过程研究现状的讨论,着重阐述了DME发动机尾气中甲酸甲酯、蚁酸、甲醛等微量污染排放物的生成机理。论述了在DME燃烧中蚁酸与NOx之间的相互作用及其对低NOx排放的影响。
This paper qave an review of combustion and pollutant formation mechanistic research within the past decade in direct-injection diesel engine operated on dimethyl ether （DME） as a kind of promising clean fuel. Together with the discussion of DME pyrolysis and oxidation reaction, especially the detailed low temperature auto ignition mechanism, the emphasis was placed on the analysis of formation mechanisms for tiny pollutant emissions, such as methyl format, formic acid and formaldehyde, and their effects on atmospheric chemistry. The interaction of formic acid with NOx and the mechanism involved the lower NOx emission formation were described. An assessment of the potential for the use of DME and related combustion research development were also introduced in the paper.
