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。????
