Because MCH dehydrogenation on board is an transient process(for example,temperature distribution & fluctuation)and is operated without the addition of hydrogen to the feed of MCH,the dehydrogenation catalysts on board exist the drawbacks of low activity during 300～350℃ and low stability at about 500℃ at present.
ＭＣＨ随车脱氢作为一种非稳态的、反应条件苛刻的过程，要求其脱氢催化剂具有良好的低温活性和高温稳定性，现有的脱氢催化剂尚难满足其要求。
The results show the auto hydrogen fuel based on MCH dehydrogenation on board seems to be feasible,and the MTH hydro.
对基于甲基环已烷（ＭＣＨ）—甲苯（ＴＯＬ）—氢（Ｈ２）的一对高度可逆反应的贮氢（简称ＭＴＨ贮氢）技术进行了较系统的研究，利用考虑随车脱氢环境的ＭＣＨ脱氢实验研究结果，对一种发动机功率为２０ｋＷ的小型氢燃料车进行了初步设计，并对ＭＴＨ贮氢技术进行了系统的能流和物流分析。
An online emulsifier and a oil water proportional control valve that can make emulsified oil on pipeline are designed.
设计了能将柴油和水在管线上进行乳化的随车乳化器及油水比例控制阀。
The paper also introduces something about the application of SAE J1939 in vehicle on board diagnosis.
从软件的角度,对基于SAEJl939的通信设计作了较为详尽的论述,并对SAEJl939在汽车随车诊断方面的应用作了一定的介绍。
