PAGE PAGE 新型环保醇基汽油相稳定性研究及其对燃料性能的影响 摘 要 汽车工业在推动经济增长的同时，对能源、环境和安全的影响也日益受到社会的关注，尤其是现在社会能源短缺，油价上涨。寻找供应稳定、排放清洁的汽车替代燃料是世界各国都非常关心的问题。醇类燃料作为液体燃料，其储运、分配、携带、使用都与传统的汽、柴油相差无几，而且其原料资源多，燃烧排放污染物低于石油类燃料，因而受到国际重视。 在本论文中，探讨、总结了世界发达国家醇类燃料汽车的产业和技术发展情况，详细的叙述了甲醇和乙醇的理化性能以及混合燃料的理化性质。甲醇（乙醇）燃料汽车发动机的性能的具体的分析和比较，使用醇类燃料能效、环境、动力性能等方面的问题。还对醇基燃料发动机的改进的具体的部件进行了理论分析等。 从中得出了醇基燃料发动机在排放、冷启动、最大功率、最大扭矩等方面的优缺点。 关键词:汽车、甲醇、乙醇、动力性能、理化性质。 Abstract Automobile industry in the promotion of economic growth, energy, environmental and safety impacts have also been growing concern in the community, particularly now that social energy shortages, rising oil prices. Find a steady supply of clean emissions alternative fuel vehicle countries in the world are very concerned about. Alcohol fuel as a liquid fuel, its storage, transportation, distribution, transportation, use both traditional gasoline and diesel is almost the same, but its raw materials resources, the emission of pollutants below the combustion of petroleum fuels, causing international attention. In this paper, the study, a summary of the worlds developed countries Alcohol Fuel car industry and technology development, detailed description of methanol and ethanol, and the physical and chemical properties of the mixed fuel properties. Methanol (ethanol) fuel vehicle engine performance of specific analysis and comparison, the use of alcohol fuel efficiency, the environment, dynamic performance, and other issues. Also on the alcohol-based fuel engines to improve the specific components of the theoretical analysis. Draw the alcohol-based fuel in the engine emissions, cold start, the maximum power, maximum torque and so on the merits. Keywords：Automobile、 methanol、ethanol、 power performance、physical and chemical properties. 目 录 TOC \o 1-3 \u 引言 PAGEREF _Toc169082720 \h 1 第一章 内外醇类燃料汽车产业发展状况 PAGEREF _Toc169082721 \h 2 1.1 国外醇类燃料汽车产业发展状况 PAGEREF _Toc169082722 \h 2 1.1.1 醇类燃料汽车在美国的发展 PAGEREF _Toc169082723 \h 3 1.1.2 醇类燃料汽车在日本的发展 PAGEREF _To
