The lighter drive 更轻便的驾驶理念Electric cars made from carbon fibre will be safer and go farther 电瓶汽车+碳纤维材料=安全，耐用They look safe in thereMARK WEBBER has a lot to thank tiny strands of carbon When his Formula 1 car cartwheeled in a spectacular 306kph (190mph) crash at the recent Valencia Grand Prix， what helped him to escape unscathed was the immensely strong carbon-fibre “tub” that racing drivers now sit Carbon fibre is an expensive alternative to making things in steel or aluminium， but besides being extremely strong it is also very It is found in high-performance parts， like aircraft wings， bits of supercars and the frames of pricey mountain But if work by Germany’s BMW proves successful， it could also become the material of choice to mass-produce electric 6月，F1瓦伦西亚大奖赛发生了惊人一幕：以每小时306公里（190英里）行驶在赛道上的马克�6�1韦伯发生了严重的翻车事故。奇迹的是，韦伯本人毫发无伤。奥妙之处就在于当下流行于F1的——碳纤维底座。虽然与铁，铝相比，它的造价较高，但是抗压及轻便性都远远好于铁和铝。目前，炭纤维材料还大多使用在高精度领域，如飞机机翼，F1赛车，或是私人山地车等。不过这一传统观念可能会被宝马公司打破，一旦试验成功，那么碳纤维就可以率先广泛应用在电动汽车领域。The Bavarian carmaker plans to launch a new plug-in electric car in It will be one of the first designed from scratch to use an electric motor rather than being converted from an existing Reducing the weight of this four-seater car， known as the Megacity concept， will be crucial to improving its performance and So BMW is planning to use no steel at The Megacity will be built as two modules: an aluminium chassis will contain the electric drive-system and battery， and a body made almost entirely of carbon fibre will be fitted onto 德国汽车制造商正计划将在2013年推出一款电瓶可拆卸式环保车。这并不是从现有车型改装而来，而是设计师卧薪尝胆的一次全新尝试。更轻便的4人坐驾，完全符合现代城市环保理念，这款“无铁”车型的设计，彰显出了它的与众不同与理念上的更新换代。但是这样一个设想目前还处在起步阶段，或许成功的那天，汽车铝制底盘上充电驾驶装置与设备，及全身碳纤维的设计工艺，能够更好的诠释大城市的环保概念。Carbon fibre is 30% lighter than aluminium and 50% lighter than The fibres are extremely tear- When woven into a lattice structure and impregnated with resin they can produce a part that is stronger than The trouble is the process is labour-intensive and slow， not least because components may have to be cured for hours under pressure in massive ovens called For carmakers， used to stamping out steel body-parts in a few seconds， this has ruled out carbon fibre for high-volume BMW， however， aims to change 碳纤维比铝轻便30%，是铁的50%。同时，由于纤维具有极强的抗断裂性，再融入树脂形成晶体结构后，那么它的强度就要超过铁。但是这道工序属于劳动密集型，效率相对较低，以前车用铁制品的切割仅需要几秒钟时间就能完成，而现在则需要在高压炉内高温锻造几个小时，因此，大量生产碳纤维的可能性不高。不过，宝马公司目前也正在试图改变这一情况。Its production line starts with a so-called precursor: a fibre spun from a This is carbonised by heating it in multiple stages to leave individual carbon fibres just seven microns (007 millimetres) Around 50，000 of these fibres are bundled together into a yarn which is then made into a This can be cut and handled like a Strips of fabric are then overlaid to align their fibres in such a way to maximise their load-bearing characteristics as required—in effect tailoring components like a bespoke 现在，宝马生产线守开先河，将聚合体加工成纤维状，这个碳化过程需要在高温下进行几道工序，最后产生的碳纤维厚度只有7微米（007毫米）。然后，大概将5000根这样的纤维拧成一股就成了纤维织物，再将这样的纤维根据它的陌生能力将它切割成最合适的尺寸，实际上，这个步骤与量体裁衣有异曲同工之妙。Along come the robots 自动机将助一臂之力BMW uses molds， heat and pressure to produce contours in the Resin is then injected into the molds to bond the fibres How the resin flows through the fibres is crucial; it has to be done quickly and leave no area untreated before it starts to A release agent in the resin migrates to the surface to prevent the component sticking in the The whole process， which can be handled by robots， is completed in 然后，再利用模具与高温将纤维织物打造成型。首先，将树脂注入模具粘合纤维，这里有两个细节非常关键，一是动作要快不能拖泥带水，二是在没有粘合之前确保模具内的树脂流向均匀。树脂中混有的隔离剂此时发挥功效，避免了纤维与模具发生粘连。整道工序，在自动仪器的协助下，仅需几分钟便可完成。The resulting carbon-fibre parts are bonded together to construct the body of the Besides their lightness， BMW’s experimental vehicles have exceeded expectations in crash tests， says the During front- and rear-impact-tests the aluminium chassis crumples to absorb energy， but leaves the rigid carbon-fibre passenger compartment Even extreme side-impacts protected the crash dummies and the battery (automatically switched off when the airbags trigger) In many cases crash damage is reparable by cutting out broken sections of carbon fibre and bonding in new 此时的碳纤维就可以应用于汽车制造。宝马公司声称：除了超轻便的特性之外，碳纤维的抗挤压能力也令人惊叹。在对车头车尾抗冲击测试中发现，一方面是铝制底盘受到挤压而变形，缓冲了部分能量，而坚硬的碳纤维能够保证车身安然无恙。即使是侧面来的强力冲击，也能够有效保护车厢内假人模型及电瓶毫发无伤（当然，气囊装置启动电瓶能够自动断电）。即便是车身有所受损，也不用担心，切割掉受损部分再粘合上新部件，完全可以让车体恢复原状。At some point， however， carbon-fibre cars will be Steel and aluminium is easy to recycle， but carbon fibre is Carmakers are working with aerospace firms on ways to do BMW has pioneered a process to reuse offcuts by breaking them up with heat to turn them back into raw This can be used to make composites with about half the strength of new carbon 铝的回收再利用技术已经非常成熟，但是从某角度来说，碳纤维这方面的技术还有待研究。目前，制造商正和宇宙空间机构合作，试图填补这一空白。眼下，处理碳纤维“边脚料”最先进的方法还是来自宝马公司，他们通过高温分解，能够使之退回成未加工状态。通过此种方法生产出的复合材料也具有碳纤维一半的硬度。Another advantage of a carbon-fibre body is that it will not So， apart from the battery wearing out in ten years or so， electric cars could last for decades (electric motors need little servicing) This will make it even harder for car designers to persuade those driving electrically to trade in their rustless， tough-as-old-boots vehicles for a new 碳纤维的另一优势在于不易腐蚀，如果不考虑电瓶10年左右的使用寿命，这种碳纤维电瓶汽车可以使用长达几十年（当然马达还是需要检修的）。与结实耐穿的靴子让人不忍丢弃一样，当设计理念再有突飞猛进的发展时，如何让使用者放弃碳纤维电瓶汽车，设计者可要好好动一番脑筋喽。英文附带汉语拼音，希望对你有所帮助。

-- Scott Perl， Albuquerque， NM A: Auto racers have told us the main advantage in filling tires with nitrogen instead of ambient air is that nitrogen tends to maintain more consistent tire pressure over a wide range of As friction between the tire and pavement drives up the temperature， air with varying amounts of moisture content responds differently and can cause inconsistencies in tire While racing drivers are more likely to notice the advantages of nitrogen than everyday drivers， we haven't heard of any disadvantages to using Skeptics question the practice， noting that ambient air is about 80% nitrogen and that it expands and contracts at the same rate as pure A number of readers say there's no appreciable difference in how the tires will react if filled with nitrogen， especially in everyday Q: Is it safe to use cruise control in rain or on wet pavement? -- Scott Brake， Westminster， C A: Car makers often warn that cruise control should be used only in light traffic on open roads and in good There have been reports of accidents involving cruise control when the car lost traction -- or hydroplaned -- in slippery Some car makers warn that the steady throttle of cruise control -- like keeping one's foot on the gas -- could cause the wheels to spin when they hit a wet or icy patch of Car-company representatives say the cruise- control warnings reflect the fact that drivers should be particularly vigilant when conditions are less than ideal， and cruising along on what amounts to partial autopilot tends to lull some drivers into a false sense of Q: If an automobile manual suggests a certain weight oil (such as， 5W-30)， would adding a quart of a different weight oil (say， 10W-40) between complete oil changes damage the car's engine? -- Gil Ehrenkranz， Potomac， M A: Probably But today's engines generally are more precisely engineered than those of 20 or 30 years Many of us at some point have topped off our cars with whatever oil happened to be available without causing damage -- at least not that we know Auto makers， however， say modern engines can be more sensitive to a change in oil weight， and using the wrong oil， even in small amounts， can hurt an engine's performance and even cause Q: What is a sequential manual transmission? How does it differ from an automatic or a standard manual transmission? -- Harry J Jaffe， Germantown， T A: A sequential manual transmission is a gearbox that requires gear changes to be made in order (first to second to third)， instead of having a shift pattern with a lever that allows the driver to skip Motorcycles have used such transmissions for decades and racing cars began using them years ago because they allow quicker Shifting is usually done through levers， buttons or The sequential transmissions advertised today -- mainly in high- performance cars such as Ferraris， Aston Martins and some BMWs -- are technically manual transmissions， except that the clutch and the gear changes are controlled The advantage is that gear changes can be made more quickly and precisely than a human shifting the old-fashioned Traditionalists say the downside is that they simply aren't as much fun to drive and require less driver

In recent years， engine manufacturers have been required to reduce the levels of nitrogen oxides (NOx) in diesel engine exhaust to meet Tier 3 emission standards required by the Environmental Protection Agency (EPA) One of the reasons for this mandate by the EPA is because NOx has been associated with respiratory disease and This requirement is accomplished by changes in engine designs that include retarded timing， raised piston rings， selective catalytic reduction and the use of exhaust gas recirculating (EGR) New engine designs use EGR to control NOx emissions by recirculating exhaust gases back into the combustion chamber to be burned a second time， thereby reducing emissions associated with health The amount of exhaust gas introduced into the combustion chamber will displace oxygen， creating cooler In doing this， many of the exhaust contaminants end up in the engine lubricating Diesel engine oils are now exposed to a higher level of contamination that can degrade the oil and damage engine There is concern that exhaust gas recirculation can have a detrimental effect on engine durability and its effects on the Oils exposed to the EGR environment show an increase in soot content， acid number (AN) and viscosity， while the engine and oil are both exposed to corrosive/acidic gases and particle According to Elizabeth Kobert who wrote a article titled “Running on Fumes” for the New Yorker， she says that there are about 9 personal cars per 1，000 eligible people in C In India， there are about 11 cars per 1，000 eligible The comparison becomes interesting when you factor in cars in the United S Kobert says that we have 1，114 automobiles per 1，000 eligible These figures help us understand why the United States is the top consumer of fossil fuels and emitter of The really frightening aspect of all of this is knowing that both China and India's economies are on a substantial growth track that will forever change the above automobile They are hungry for all of the amenities that are synonymous with a comfortable modern life and driving is one of The urbanization of China has been dramatic over the past Peasants have left the countryside for jobs in urban areas and the promise of a better As a result， urban areas have sprung up almost overnight to accommodate the boom in With a population if over 1 billion people， China has over 200 cities with at least 1 million As they increase their income， they will have expendable income that will allow them to purchase The future looks bright for car sales in China and I Kobert argues that if China and India were to reach car ownership at just half the numbers of American drivers， those two countries would burn through 100 million barrels of oil a If they were to match the number of United States drivers， they would need 200 million barrels of oil a To the average person these numbers appear quite meaningless until you understand that the current total world consumption a day is about 86 million barrels of This level of oil production has plateaued since December of 2005 and many are worried that we have begun the inevitable decline in our ability to pump oil at these This would all be just an interesting academic discussion if it weren't for the fact that 35 billion dollars was just sucked out of our economy due to the increase in fuel prices as we were heading into the Christmas Money spent on fuel is not money spent on the A recent poll by by Gfk Roper Public Affairs and Media reports that 27 million Americans will need to borrow money to pay their fuel bills this winter， 20 million of them will use credit cards to pay for heat to stay This comes at a time when utility companies are expanding the payment options for households and for many this includes credit As we look forward， a prudent person would understand that we are facing several enormous First of all， the world must drastically reduce the amount of carbon we are releasing into the An increasing reliance on the internal combustion engine will obviously seal our If we were to develop an alternative car right now that does not emit carbon it would take years to replace the current stock of The average car stays on the road for 7 The hundreds of millions of vehicles on the road right now will be with us for years to As China and India add to their vehicle stock， it is likely that these vehicles will live out their life cycle as Lastly， it is clear that if we continue to burn fossil fuels we will all be competing for a dwindling The laws of economics tell us that prices will increase as demand outstrips The future appears The implications for increased military conflict to secure our energy future has already begun and will worsen as supply
