甲醇汽油对发动机油低温性能的影响

【课题分析部分】

主要内容:该课题主要是为考察甲醇汽油对发动机油低温性能的影响,通过向

发动机油中添加甲醇汽油及其模拟燃烧产物甲酸、甲醛,分析其对油样的倾点、凝点、低温动力黏度的影响。课题中涉及的概念主要有甲醇汽油、发动机油和低温性能,需针对甲醇汽油对发动机油低温性能的影响进行深入的探索。

主题的现状:随着现在油价不断上涨,甲醇汽油和汽油相比更省钱,并且甲醇

汽油在一定的配置比例上和汽油的各种性能完全一样。甲醇汽油也必定是未来新型能源,并占据整个市场;但是对于甲醇汽油及其燃烧产物对发动机油的低温性能的影响的研究有待继续,我们需要不断考察甲醇汽油对发动机的低温性能的影响,从而提高燃烧甲醇汽油的技术水平。

近 萎出,寻找可替代的高效清洁石油替代燃料,来缓解石油资源短缺、能源不足的压力,保证我国的能源安全和环境保护已成为我国发展的一项重点任务。我国的能源状况是“缺油、少气、富煤”。甲醇燃料的低热值比汽油低,仅为汽油的46% ,因此当在汽油机上燃用甲醇时,应增大循环油量从而使混合气的热值大体与汽油空气混合气相等或略高。

描述 The matter extracted from palm oil was considered as gasoline additive. 翻译:这种棕榈油可看作是甲醇汽油添加剂。

The effect of various percentages (0.2%, 0.4% and 0.6%) of the bio-additives on fuel economy of SI engine respectively running on prime gasoline, gasoline with known compo- nents, ethanol gasoline, and methanol gasoline under typical urban operation condition 2000 r/min was investigated. The results showed that the bio-additives can remarkably improve the fuel economy of SI engine while operating on all kinds of fuel. The optimal ratio of bio-additive to gasoline depends on the fuel used and on the different engine operating conditions. Besides, the experiments of constant volume combustion bomb, analysis of in cylinder processes, the synchrotron ra- diation and high-temperature friction were conducted to probe into the mechanism of the bio-additive impact on fuel economy. It indicated that the bio-additives can increase the maximum cylinder combustion pressure, improve exhaust emissions and largely reduce the frication coefficient.

The continued depletion of crude oil reserves has led to substantial research in alternative fuel technologies.

翻译:由于原油储备的大量耗竭,需要研究代用燃料例如甲醇汽油的技术。 In this regard, the conversion of various organic compounds to gasoline range hydrocarbons on Mobils synthetic zeolite, ZSM-5, has received considerable research and industrial interest. Pellets of ZSM-5 catalysts have been investigated in fixed and fluidized bed processes for methanol conversion to gasoline. Novel reactor configurations featuring catalysts supported on monolithic or honeycomb structures are being increasingly used for a number of industrial applications. Their unique construction and ease of operation offer advantages over traditional reactor types. In this research, an innovative zeolite-coated monolithic reactor is employed to convert methanol to gasoline-range hydrocarbons. Experimental results demonstrate that the overall conversion and hydrocarbon product distribution compare favorably with data reported for fixed and fluid bed reactors. Mathematical modeling establishes that the reaction rate is controlled by gas diffusion into and out of the molecule-sized intracrystalline pores of the zeolite structure. This finding is of considerable importance because it demonstrates the suitability of monolithic reactors for zeolite-based catalytic processes.

In consideration of the importance of a fuel specification common to both Otto-type and Diesel-type methanol engines for practical use of methanol, effects of the use of near-neat methanol on engine performance and NOx emission characteristics were studied using heavy-duty direct-injection methanol engines. The results obtained on direct-injection

spark-ignited methanol engines fueled with M85 are as follows: (1) The inlet temperature to the catalytic converter must be raised through intake throttling or by other means. (2) NOx emissions are lower mainly due to the flame temperature of methanol which is lower than that of diesel oil. (3) The exhaust gas recirculation is effective for NOx reduction. (4) At the same level of NOx emissions, the brake thermal efficiency with methanol is lower at low loads but higher at high loads than that with diesel oil. (5) A high ignition stability is achieved over a wide operational range. Number of references: 4

翻译:燃料规格的甲醇混合少量的汽油能够有效改善冷甲醇汽油发动机的发动性能和其它好处。

In consideration of the importance of a fuel specification common to both Otto-type and Diesel-type methanol engines for practical use of methanol, effects of the use of near-neat methanol on engine performance and NOx emission characteristics were studied using heavy-duty direct-injection methanol engines. The results obtained on direct-injection spark-ignited methanol engines fueled with M85 are as follows: (1) The inlet temperature to the catalytic converter must be raised through intake throttling or by other means. (2) NOx emissions are lower mainly due to the flame temperature of methanol which is lower than that of diesel oil. (3) The exhaust gas recirculation is effective for NOx reduction. (4) At the same level of NOx emissions, the brake thermal efficiency with methanol is lower at low loads but higher at high loads than that with diesel oil. (5) A high ignition stability is achieved over a wide operational range. (4 refs.) Main Heading: Internal Combustion Engines

-------------------------------------------------------------------------------- Conversion of methanol to gasoline Abstract

This invention relates to a process for converting alkoxy compounds into hydrocarbon compounds, mostly in the gasoline boiling range. This process proceeds with low heat exchange duty requirements for heating the alkoxy compounds and recycle streams used as feedstocks and for final cooling of reaction product gases for recovery of hydrocarbon product while at the same time offering an improved choice of operating conditions. As may be desired, steam may be added to obtain a desired final steam partial pressure in all catalyst contacts with the alkoxy compounds.

ABSTRACT

In order to study the engine oil performance when methanol gasoline is used, simulation and road test were proposed. In simulation case, oil sample was dubbed by methanol gasoline and combustion products formic acid and formaldehyde and analysis was of sample oil of detergent-dispersant performance, antiwear performance, oxidation performance and low temperature performance. The test result indicates that the detergent-dispersant performance, antiwear performance, oxidation performance and low temperature performance were effect negatively. The methanol gasoline with medium ingredient methanol has more significant influence. Road test result shows that gasoline oil got worse quickly, and

23

periods of oil change got shorter using the methanol gasoline with 15% methanol. The integrated analysis indicated that methanol gasoline has great negative impact on engine oil.

Abstract:

In the first part of this three part paper, published in January 2002, we dealt with enhancing the performance of low temperature proton exchange membrane fuel cells by improvements to the platinum-based cathode materials and to the cathode design. In this second part of the paper we shall discuss the improvements in the reformate (CO and CO2) tolerance at the anode and in extending the MEA durability. Improvements have been achieved by advances in platinum/ruthenium electrode design, in the application of bilayer anodes for durable air bleed operation, and in the addition of a water electrolysis electrocatalyst to the anode for cell reversal tolerance. In the third part of the paper the particular challenges presented by the direct methanol fuel cell will be discussed. References: 20 references open in new window

【综述部分】

归纳、整理及分析比较:综合以上资料,由于目前经济大发展及汽车用户的

增加,再纵观目前用油情况,当前汽柴油的供应已出现严重短的缺。国家政府为了缓解石油资源的短缺状况曾提出各种新能源的使用,其中包括生物柴油、天然气、液化石油气、乙醇以及电动汽车等各种措施,但就目前来看甲醇是最理想的选择。甲醇汽油是车用燃料替代油,是目前新能源的重要组成部分。 显然,甲醇汽油是一种很不错的清洁能源,且动力性好,然而,在使用甲醇汽油的过程中,其必定会对发动机油的低温性能产生这样或者那样的影响,普通汽车的发动机难以适应并充分利用其燃烧产生的能量,另外,甲醇在生产或燃烧过程中会产生少量的甲醛或甲酸,因此,甲醇汽油对发动机有一定的腐蚀性。因此,研究甲醇汽油在使用的过程中对发动机的影响,从而提高替代油的利用效率。

历史背景、现状和发展方向:早在20世纪70年代 油危机斤不久,国内就已

经开始了甲醇替代燃料的探索性研究,甲醇汽油是一种很不错的清洁能源,自提出以来就受到政府的很大重视,解决当前的能源问题刻不容缓,甲醇汽油是根据社会的需要,而必然产出的产物。随着能源价格的上涨,甲醇汽油是社会的需要。市场前景,发展潜力,可想而知。????

25

甲醇汽油是一种\以煤代油\路径,可以作为汽油的替代物从而实现对原油的部分替代。由于当前能源的不断减少,需求量的不断增加,甲醇汽油必定成为未来的重要发展方向;政府要加大对甲醇汽油的研究,不断提高它的技术水平和使用效率。近年来,甲醇由于具有动力性能良好、热效率高、比能耗低及低排放性等优点,可以作为新型代用燃料,从而受到了广泛的关注。目前,甲醇汽油等混合燃料的研制已基本成熟。虽然甲醇汽油的使用会带来一定的不利影响,但是甲醇可以完全燃烧,因此前景十分广阔。

【学习本课程的意见与建议】

困难:通过整个专题报告,遇到了不少的困难,首先,对于专题并不了解,平常接触的比较少与专题相关的专有名词,对其本身的定义不是很了解,搜索起来比较难;其次,有些数据库并没有想要的文献资料,或者搜出来的都是一些相关度不大的文献;还有就是,在英文数据库中,整个网页都是英文,难以找到相关资料,况且与本专题相关的文献较少,大大增加了搜索的难度。

解决方法:通过浏览相关网站深入了解专题;比较搜索出来的相关文献,从而得出与专题最相关的文献。

收获:在本课程的学习中,我学会了使用数据库更高效率地查找资料,还有就是浏览一些外国的相关文献,了解更多的知识;还有就是,提高处理分析文献和归纳总结能力。

考试方式:现行的考试方式不合理,随着时代的发展,人们教育观念的更新,智力已不再是能力的同义词,现实问题的复杂化和综合程度的提高以及知识更新速度的加快,要求人不仅要具备独立解决问题的能力,更要具备与他们之间的合作能力,处理问题的应变能力、持续性的学习能力、自我激励能力和自我提升的能力等素质。简言之,社会需要的是全面的综合性高素质人才。显然,\应试教育\这种教育倾向不能适应社会人才培养的需要,而且还会有碍于教育事业的健康发

26

展,尤其是基础教育的发展。

建议:首先,理论知识不应该讲的那么快,要合理的放慢一下速度,这都是一些比较抽象的名词,毕竟理论知识也要深入了解一下,这样才能更好地去动手实践;还有就是在做作业那一部分,希望可以对某些难的题目更好的演示一遍,好让我们有个方向,知道到该如何去完成。

思考:利用数据库可以更好地更高效率低找到我们想要的资料,但是为什么有一些文献只能是校园网才能下载阅读?甲醇汽油能否更好更高效率地替代汽油?甲醇汽油对发动机油低温性能的影响?
