中文摘要: 柴油引燃均质高辛烷值甲醇混合气是压燃式发动机实现高效燃烧的一种有前景的方式。但是,这种高着火差异性的二元燃料燃烧化学反应动力学及其燃烧特性尚未得到充分认识。本课题主要研究内容是:1)揭示高着火性燃料在着火性不良燃料均质混合气中的着火和燃烧化学反应动力学机理,构建着火模型;2)研究两种不同着火性燃料的高温燃烧特性,阐明二元燃料燃烧时的相互作用;3)研究压燃式发动机应用不同着火性二元燃料时的燃烧边界及其拓宽途径,建立二元燃料燃烧过程的控制方法;4)研究二元燃料在压燃燃烧时的排放物生成特性,提出排放气体无害化的技术途径。在以上工作基础上建立二元燃料燃烧化学反应动力学模型,创建内燃机二元燃料燃烧理论,促进发动机燃料多元化利用和发展。

英文摘要: That the methanol mixture with high cetane number is ignited by diesel fuel in compression is a promising mode for multiple fuels combustion. However, the mode has not been fully understood in the fields of combustion so far. The goals of the project will focus on following main aspects,1)to reveal the chemical kinetic mechanism of the fuels with differenct ignition property and to establish their ignition models; 2)to investigate into combustion characteristics in high temperature for the dual fuels , then to obtain the knowledge about their interaction in burning;3)to determin their burning boundary or limitationsand find out the ways to extend them, then bring out the methods to controll the burning process for dual fuel; 4)to investigate on exhaust emission production for dual fuel in compression ignitioni, thus to give the harmless ways for those emissions。Through the work mentioned above,a chemical kinetic mechanism and combustion model as well as a theory for dual fuel will be established, to promote development of mutiple fuel utility in future.
