我们是如何试车的 来自AK的品车指南

什么样的设计称得上大气?什么样的车内环境让人舒适?什么样的动力表现叫做充沛?什么样的操控才有乐趣?如果你不能以迅雷不及掩耳盗铃之势马上回答,这篇文章里会有你想要的参加汽车厂商的试车活动时,我时常会遇到两类让我哭笑不得的记者。第一类记者的代表形象是中年妇女,视试车如浮云,活动对他们而言本质上等于免费旅游;第二类记者在工作态度上要端正很多,但     

陈震:我相当讨厌二环十三

事出有因:《汽车与运动》专访"二环十三"一陈震陈震是玩车这个圈子里的典型代表,喜爱汽车改装、追求个性和自我、叛逆,并且狂热的执着于汽车速度带来的快感。他们都很单纯、很简单、而且也略显幼稚。很多人都在关注他们,其实也是关注自己,谁不想疯狂地飙一回,谁没有自己的赛车梦呢?不管是改装、飙车还是赛车,在如今这个充满人性化的社会里,各方都做好自己的本分吧。还是那句话,宜疏不宜堵。

有则改之

<正>玩车的最高境界是什么?我觉得就是有则改之。玩车,自然要比以车代步高一个层次。厂家在个性化选择方面再不遗余力,也很难满足每个车主的所有要求。欲求不满怎么解决,自然是添装、改进和升级了,这样就产生了玩车的人,他们不会局限于汽车的固有配置,倒是更享受DIY的过程和得偿心愿的乐趣。对于他们而言,玩就是为了更好地驾驭汽车,驾驭生活。

拥有奔驰 S 级轿车会让人兴奋吗?很多人说不会,他们忘不了付出了100多万元的代价。如果只用 C 级车的价格就能获得接近于 D 级车的享受,那就的确让人兴奋了。不只是第八代雅阁,如今逐渐增多的越级车型似乎为汽车市场注入了一针兴奋剂,使本来已经白热化的竞争变得更加激烈,而即将上市的现代劳恩斯无疑更是火上浇油。     

Measurement of soot oxidation with No<Subscript>2</Subscript>-O<Subscript>2</Subscript>-H<Subscript>2</Subscript>O in a flow reactor simulating diesel engine DPF

Understanding the mechanism of carbon oxidation is important for the successful modeling of diesel particulate filter regeneration. Characteristics of soot oxidation were investigated with carbon black (Printex-U). A flow reactor system that could simulate the condition of a diesel particulate filter and diesel exhaust gas was designed. Kinetic constants were derived and the reaction mechanisms were proposed using the experimental results and a simple reaction scheme, which approximated the overall oxidation process in TPO as well as CTO. From the experiments, the apparent activation energy for carbon oxidation with NO₂-O₂-H₂O was determined to be 40±2 kJ/mol, with the first order of carbon in the range of 10∼90% oxidation and a temperature range of 250∼500°C. This value was exceedingly lower than the activation energy of NO₂-O₂ oxidation, which was 60±3 kJ/mol. When NO₂ exists with O₂ and H₂O, the reaction rate increases in proportion to NO₂. It increases nonlinearly with O₂ or H₂O concentration when the other two oxidants are fixed.

<TPL-PCRUN> Statement of methods

TPL-PCRUN is a software program for the dynamic interaction simulation of pantograph–catenary systems. In the benchmark, based on the finite element method, the catenary model was built and the pantograph was considered as a three-level spring–damper–mass system. Then, through the contact definition between pantograph and catenary, the coupled model of the pantograph and catenary system was established. The respective dynamic equations of motions were solved by the time integration method. Thus, the simulation results were obtained and submitted for the comparison with the other software. On the other hand, a standard model from EN50318 was established and analysed by TPL-PCRUN. The simulation results by TPL-PCRUN were remarkably consistent with the reference values given by EN50318. It was proved that the results by TPL-PCRUN can be reliable. Recently, the software has been updated and improved. Some new models and algorithms are proposed, including the rigid–flexible hybrid pantograph model, contact definition considering appearance characteristics of the contact surfaces, a fluid–solid coupling algorithm of the pantograph and catenary system, etc.

Study of n-C<Subscript>12</Subscript>H<Subscript>26</Subscript> reforming over DFC catalyst in a simulated diesel exhaust

In lean-DeNOX catalysis reactions, hydrogen is a good reducing agent in PGM catalysts as well as an effective promoter in selective catalytic reduction reactions over base metal oxide catalysts. However, such a lean-DeNOX system, which uses hydrogen, requires an on-board fuel reforming system applicable to internal combustion engines. In this study, catalytic partial oxidation (CPOx) performance was tested in a laboratory for various reactants and hydrocarbon conditions. Volume concentrations of 5–10% oxygen and 0-5% water vapor were used to simulate diesel exhaust, and n-C₁₂H₂₆ was used as the feedstock for the reforming reaction. In the CPOx of n-C₁₂H₂₆, the highest hydrogen selectivity was 64% and was achieved at 100,000 h-1 GHSV. Additionally, the C/O ratio was less than unity in the absence of water vapor. However, as the water concentration was increased to 2.5 and 5.0 vol. % in the n-C₁₂H₂₆ CPOx reactions, the maximum hydrogen selectivity was increased from 64% in the absence of water to 70% and 75%, respectively. This effect is a consequence of the water-gas shift reaction over the catalyst bed. Regarding oxygen concentration effects, hydrogen selectivity slightly increased with increasing oxygen concentration from 10% to 15%. It was also found that the CPOx reaction of n-C₁₂H₂₆ can be ignited at temperatures below 300 C. Accordingly, it can be concluded that CPOx is a useful and feasible device for promoting diesel DeNOx catalysis in terms of hydrogen productivity and reaction initiation.
