发动机燃用生物柴油燃料的试验研究详解.doc

摘 要 面临激烈的国际竞争，我国发展到了一个关键时期，迫切需要探索新的发展途径。同时开发生物质能源是解决全球能源危机的方向之一，当前世界各国对生物质能的研发非常重视。其中重要的一项分支就是以油料作物等可再生资源为原料制成的生物柴油。由于生物柴油是一种可替代石化柴油的清洁安全的新型燃料，具有优良的环保特性和可再生性，属理想的“绿色能源”，因而在能源危机的今天备受重视。选择油料产业与能源产业的交叉领域生物质能特别是生物柴油为契合点，研究油菜生产与生物柴油发展，不仅为解决能源危机提供了新的视角，而且对于保障能源安全、保护生态环境、促进农业和制造业发展、提高农民收入等都具有重要的战略意义。 论文主要研究了生物柴油的燃烧特性，和与柴油混合燃烧的特性。本研究选择了乌桕籽来作为生物柴油的原料，并且自制了此类生物柴油用于试验研究。通过试验得到不同燃料的燃烧时的气缸内压力和排放数据，进行分析，从而得到不同燃料的燃烧特性以及排放特性，为生物柴油的使用，以及减少排放等分析提供试验依据。 本文特色在于试验的数据很丰富，采用了多工况，多种燃料进行试验，因此可对比方面很多，为后来者提供试验依据起到很好的作用。并且自制生物柴油，对于拓展生物柴油的来源，鼓舞大家一起研究新的来源提供的依据。也体现了克服困难坚持科研的精神。 关键词：生物柴油；柴油机；气缸内压力；排放。  Abstract Facing the fierce international competition, our country has developed into a key period, and we need to explore the new approach to develop the oil industry urgent. It is one of the orientations of solving the global energy crisis to develop the biomass energy; the countries all over the world pay much more attention to the research and development of biomass energy at present. One of important branches is the biodiesel oil made by the renewable resources as raw materials, such as oil crops, etc. , it is a kind of new-type fuel with safe cleanness that can substitute the petrochemical industry diesel oil , because it has fine environmental protection characteristic and renewable , belongs to the ideal ” green energy ” . The ones that choose to research the biomass energy of fields , especially biological diesel oil, which crossed the fields of the oil industry and the energy industry, study on the rape production and development of biodiesel, has an important strategic meanings for the energy security, the ecological environment protection, promoting agriculture and manufacturing industry development, raising peasant’s income, etc.. The thesis studied the combustion characteristics of 100% biodiesel and biodiesel mixed with diesel. In the study, the biodiesel of Chinese tallow tree seeds are self-made bio-diesel for the experimental study. According to the experiments, we can receive the
