本科毕业设计(论文)题目名称：柴油机上掺烧二甲醚的讨论和 系统设计 学 院：专业年级：学生：班级学号：指导老师：二 XXX 年六月十日摘要随着人们对环境污染重视程度的提高，世界各国对燃机排放的限制也日益严格。二甲醚燃料是国际上近年来新出现的很有进展前途的超低排污代用燃料。在各种柴油机上的试验结果表明，二甲醚能够实现柴油机高效、超低排放、柔和无烟燃烧。鉴于目前二甲醚的产量较低，且生产成与运输本也较高的现状，我们进行了柴油机上掺烧二甲醚的讨论。这样充分利用二甲醚好的雾化特性和柴油好的润滑特性，不仅可以降低排放，而且解决了燃用纯二甲醚燃油系统磨损问题和泄漏问题。本文通过二甲醚现状、生产工艺、以与二甲醚的特性的分析,对在柴油机上掺烧二甲醚进行了比较全面的讨论,并对掺烧系统做了相关的设计。关键词：柴油机 二甲醚 掺烧 系统设计AbstractWith people’s increased attention to the environmental popllution,the emissions from the internal combustion ergine in conntries all over the world are also increasingly stringent restrictions.DME fuel which emerges internationlly is the promising ultra-low-emissions alternative fuel.It’s shown by the test result in all kinds of the diesel engine’s combustion efficient,ultra-low emission and soft smoke-free.Because of the current low production of DME,the high cost of the production and transport,we make a study about belending with DME in the diesel engine.By making full use of the dimethyl ether’s good atomization and the diesel engine’s good characteristics of lubricating,emissions can be reduced and leakages problems of the burning pure DME fuel system can be solved.By analysing the DME’s status quo,production technoloy and the DME characteristics, a comprehensive study and a system design about belending with DME in the diesel engine is made in this paperKeywords：DieselDimethyl etherDlended withSystem Design目录摘要 IAbstractII1 绪论 51.1 引言 51.2 课题讨论的目的和意义 52 二甲醚的现状 62.1...
