摘　　要：对高原环境下使用柴油、其它新型燃料及加入助燃剂柴油的柴油机在经济性、动力性、排放性等方面进行对比,论述国内在醇类燃料、醚类燃料、沼气-柴油双燃料、无灰助燃剂及其他生物燃料等方面研究所取得的进展,着重分析各种燃料在经济性、动力性、排放性等方面的差异,指出现有研究的现状和不足。针对醇类燃料与柴油燃料难以完全互溶、双燃料需对发动机的燃烧室及供油系统等主要部分进行改装、无灰助燃剂的生产和成分计量困难因而加入量受到限制等各种新型燃料存在的问题,研究利用氮气吸附法从进气源头上减少氮气含量,提高进气含氧量,从而提高和改善柴油机在高原环境下的经济性、动力性和排放性能。In the plateau environment, the diesel engine, other new fuel engine and diesel engine with combustion promoter are compared in terms of economy, power and emission.The progress made in domestic research on alcohol fuels, ether fuels, biogas-diesel dual fuels, ashless combustion promoters and other biofuels is discussed with the focus on the differences of various fuels in terms of economy, power and emission, and also the shortcomings of existing research are mentioned. Due to the facts that the alcohol fuel and diesel fuel are difficult to completely dissolve, that the addition of dual fuels requires modification of the main parts of the engine′s combustion chamber and fuel supply system, that different problems exist in new fuels such as the limitations of the amount of addition brought about by the production and component measurement difficulty occurs in the process of ashless combustion promoter, the principle of nitrogen absorption is introduced to reduce the nitrogen content from the source of the air intake, increase the oxygen content of the intake air, improve the economic, dynamic and emission performance of the diesel engine in the high-altitude environment.
