摘 要：本文阐述了发展压缩天然气汽车(CNG)的环保低污染性、安全性、经济性及CNG汽车和加气站的发展前景及对策。
关键词：压缩天然气汽车；加气站；发展前景；对策
目前，我国一些大城市的汽车尾气排放是城市大气污染的主要源头，因此，发展清洁能源汽车已成为刻不容缓的的选择。压缩天然气汽车(CNG)以其能耗低、污染物排放量小而受到各国的欢迎，是国际公认的最理想的车用替代能源。发展天然气汽车对于解决环境问题和能源问题都具有重要意义。
一、天然气汽车的发展情况
l、国外天然气汽车发展概况
为保护环境减少污染，许多国家政府颁布了一系列法规及出台一些鼓励性政策，促进燃气汽车发展，如制定更严格的汽车尾气排放标准，在天然气供应、汽车购置税费，设备供给、加气站建设等方面给予资金、税收优惠政策。
美国联邦政府1992年颁布的《能源政策法》，对于购买或改装代用燃料汽车及加气站的建设减免税作出详细规定，同时还颁布了使用天然气的减税政策，并免征天然气公司的汽车燃料销售税。有40多个州根据联邦政府的政策、法律，制定了本州有关强制和鼓励使用CNG等清洁燃料汽车的政策和措施，推动了CNG汽车发展和加气站建设。目前，全世界已有40多个国家拥有燃气汽车，主要分布在天然气资源丰富的意大利、新西兰、阿根廷、巴西等国家和环保法规严格的美国、日本等国。
2、我国天然气汽车发展概况
20世纪80年代中期，我国引进了部分CNG加气站设备，在四川建立了我国第一个CNG加气站；1993年中国石油天然气总公司系统引进国外有关技术并于 1996年将加气站装置和汽车改装部件引进技术国产化、技术标准规范化。1999年全国清洁汽车行动协调领导小组成立，启动了北京、天津、上海、西安、深圳等12个试点城市地区的清洁能源推广应用工作，在CNG汽车的推广应用和加气站建设方面取得了前所未有的成效。根据有关部门统计数字，截止到2004年我国一些地区共有天然气汽车20多万辆，加气站700多座。
二、天然气汽车(CNG)与其它燃料的环境、经济效益比较
压缩天然气汽车：
天然气压缩至20MPa于汽车用压缩天然气钢瓶中，经减压器后供给内燃机。
以CNG作汽车燃料与汽油相比具有以下优点：
l、降低污染，改善大气环境：天然气是一种清洁能源，具有热值高、效率高、污染小等特点，燃烧比较完全，不易积碳，CO、NOx和微粒的排放量均低于汽油，排气污染明显降低。机动车尾气是城市大气污染主要来源之一，其中主要有害成分是一氧化碳(C0)、碳氢化合物(HC)、一氧化氮(N0)和二氧化氮 (NO2)等。据有关资料显示，使用天然气作为汽车燃料与汽油作燃料相比可以减少排放90％CO、90％S02、72％HC、39％NOx、 24％CO2、无粉尘排放，对改善城市环境有显著作用。典型的柴油机与汽油机及天然气机排放情况比较见表l。
2、CNG汽车有较高的安全性
与汽油相比，压缩天然气是相对安全的燃料。
(1) 天然气爆炸下限为5％，比汽油(爆炸下限为l％)高，甲烷燃点为645℃ ，比汽油燃点高218℃，相比不易点燃。甲烷密度低，相对密度为0．55左右，泄漏的气体很快会在空气中散发，在自然环境中难以形成遇火爆燃的条件，一旦压缩天然气从储罐或管路中泄漏，泄漏点周围会立即形成低温区，使天然气燃烧困难。因此CNG是一种相当安全的汽车燃料。天然气与汽油的燃料特性比较见表2
(2)天然气汽车的钢瓶系高压容器
(20MPa)，其材质及制造、检验试验在各国均有严格的规程控制，在我国有《汽车用压缩天然气钢瓶标准))(GBl7258—1998)。
钢瓶安装有防爆设施，减压器、阀门等设备，严密度标准高，供气系统安全可靠，不会因汽车碰撞或翻覆造成失火或爆炸，而汽油汽车的油箱系非压力容器，着火后容易爆炸。
3、有利于缓解能源紧张的供需矛盾。
我国经济正处于高速发展阶段，汽车数量以100万辆／年以上的速度递增，对汽油资源需求大量增加，我国每年需要进口大量原油、成品油和LPG。使用燃气汽车可优化
汽车燃料供应结构，改变了汽车燃料只有汽油、柴油的格局，既缓解了汽油供应紧张的问题又满足交通事业发展的需要。
4、可延长发动机寿命。天然气容易扩散，以气态进入发动机，在发动机中容易和空气均匀混合，燃烧比较完全、干净；可以提高热循环效率，加快燃烧速度，充分利用燃烧热能；同时CNG辛烷值高，抗暴性能好，使用时不需要添加抗暴剂，不会稀释润滑油，因而使发动机气缸内的零件磨损大大减少，使发动机的寿命和润滑油的使用期限大幅度增长。所有这些都会降低汽车的保养和运行费用，从而提高汽车使用的经济性。 5、有较高的经济效益。目前，国内汽油价格持续上升，价格体系已和世界接轨，使用CNG汽车将能节省近40％燃料费用，见表3。
三、CNG汽车的发展前景
CNG汽车和加气站具有广阔的发展前景，主要表现在以下几方面：
l、汽车保有量的飞速增长、石油资源和环保的严峻形势，决定了发展天然气汽车成为解决能源问题和环境问题的重要途径。
2、“十一五”期间，新型清洁能源汽车已被列入《国家科技发展中长期规划》，国家将继续组织实施涉及各种清洁能源汽车的重大科技项目，重点支持包括天然气汽车在内的整车、零部件等关键技术，将进一步促进天然气汽车的发展。
3、我国天然气资源大规模开发及管道建设步伐加快使发展CNG和加气站成为可能。根据我国天然气利用规划，近十年“西气东输”、“陕京二线”等一大批输气管道及沿线城市燃气管道相继建成，我国大规模利用天然气的基础设施逐步完善，天然气加气站也将逐步形成网络。
4、发展CNG汽车具有稳定的气源保证，以天津为例，目前天津市已建立了完善的天然气输配系统，由陕北、大港、华北等油田向天津供气，2005年年供气量近6 亿m3，2006年预计达8亿m3，管网长度6894km，其中，高压管线591km，为“十一五”期间天津市大力发展CNG汽车大规模建设加气站提供了保证。
四、CNG汽车和加气站发展对策探讨
为加快以天然气为燃料的清洁汽车的发展，提出以下建议：
1、政府出台鼓励和扶持政策：世界各国发展经验表明，政府的支持是加快发展的必要条件，其经济政策是影响其发展的重要因素，应在法律方面予以保障，在燃气汽车生产、改装、零部件生产，加气站建设，燃气汽车购买和使用、维修等环节制定价格、税收、投资、补贴等方面配套的优惠政策。燃气价格是影响燃气汽车发展的重要因素，只有燃气价格与汽油价格形成足够大差价时，燃气汽车的发展才具有经济基础和推动力。
2、加强领导，实行统一管理。发展CNG汽车必须建设优质、便利的加气站，需要规划、公安、消防、劳动、技监等部门的支持。
3、在市政规划中，加气站与加油站应统筹考虑，合理布局，协调发展。尽量利用现有土地资源，在确保环境安全的前提下建设油气合一站。
4、遵循CNG汽车与加气站同步发展的原则，只有在加气站成网的条件下，CNG汽车才能真正发展。同时也只有CNG汽车规模到了一定数量，加气站才能正常运转，实现盈利。
5、严格法律制度：制定严格的汽车尾气排放法规，切实做到不达标车辆坚决不予以上路，对CNG汽车改装厂的资格进行严格审查，认证。首先应将城市城市公交车、出租汽车作为CNG汽车发展的重点，杜绝部分公交车冒黑烟污染环境的现象。
6、加大宣传力度。目前，天然气汽车尚处于起步阶段，社会公众对它的环保性，安全性，经济性，可靠性还不充分了解，所以，要进行广泛的社会宣传，努力提高人们对汽车尾气危害性的认识，使人们了解CNG是清洁、安全、经济的车用燃料，使发展天然气汽车得到社会各方面的认可和支持。
压缩天然气汽车由于其显著的经济效益和社会效益将成为天然气市场开发应用的一个新领域。在环境保护越来越受到重视的形势下，随着天然气资源的开发和应用领域的拓宽，此举将是减轻环境污染压力、缓解石油紧缺，实现可持续发展的可靠保证。
Abstract: This paper describes the development of compressed natural gas vehicles (CNG) on environmental protection of low-pollution, security, economic and CNG cars and filling stations and prospects for the development of countermeasures.
Key words: compressed natural gas vehicles; stations; development prospects; Countermeasures
At present, China's major cities is a urban vehicle emissions a major source of air pollution, therefore, the development of clean energy vehicles have become the choice of the delay. Compressed natural gas vehicles (CNG) in their low energy consumption and emissions by all countries small and welcoming, is recognized internationally as the best alternative energy vehicle. The development of natural gas vehicle to address the environmental issues and energy issues are of great significance.
First, the development of natural gas vehicle
l, development of foreign natural gas vehicle
Rece pollution to protect the environment, many countries have issued a series of government regulations and the introction of a number of incentive policies to promote the development of gas vehicle, such as the development of more stringent vehicle emission standards, in the natural gas supply, car purchase taxes and fees, equipment supply, gas station construction grant funds, tax incentives.
In 1992 the U.S. federal government enacted the "Energy Policy Act," or modified for the purchase of alternative fuel vehicles and the construction of stations in detail the provisions of the tax relief, but also enacted a tax cut that the use of natural gas and natural gas companies exempt from motor vehicle fuel sales tax. There are more than 40 states in accordance with the policy of the federal government, law, drawn up on the mandatory state and encourage the use of clean fuel CNG vehicles, such as policies and measures to promote the CNG filling station development and construction of motor vehicles. At present, more than 40 countries around the world have a gas car, mainly in the rich natural gas resources in Italy, New Zealand, Argentina, Brazil and other countries and stricter environmental regulations the United States, Japan and other countries.
2, China's Natural Gas Vehicle Development
80 In the mid-20th century, the introction of some of our CNG filling station equipment, set up in Sichuan's first CNG filling stations in China; in 1993 the China National Petroleum Corporation on the introction of foreign technology systems in 1996 installations and will be filling stations modified car parts made of the introction of technology, standardization of technical standards. 1999 National Clean Automobile Action Coordination Leading Group was established to start the Beijing, Tianjin, Shanghai, Xi'an, Shenzhen and other cities in 12 pilot areas to promote the application of clean energy in the popularization and application of CNG vehicles and filling stations has made an unprecedented building results. According to relevant statistics, as of 2004 there were some areas of China's natural gas vehicle more than 20 million vehicles, more than 700 filling stations Block.
Second, natural gas vehicle (CNG) fuel and other environmental and economic benefits compared
Compressed natural gas vehicles:
20MPa compressed natural gas in the car to compressed natural gas cylinders in use by the supply of internal combustion engine after the pressure recer.
To CNG fuel for vehicles compared with gasoline has the following advantages:
l, rece pollution and improve the atmospheric environment: natural gas is a clean energy, with a high calorific value, high efficiency, pollution, etc., the comparison is totally burned, not carbon deposition, CO, NOx and particulate emissions than gasoline, significantly reced exhaust pollution. Motor vehicle exhaust is the major source of urban air pollution, one of which is carbon monoxide harmful ingredients (C0), hydrocarbons (HC), nitric oxide (N0) and nitrogen dioxide (NO2) and so on. According to the data, the use of gas as a motor fuel and gasoline as fuel can rece emissions compared to 90% CO, 90% S02, 72% HC, 39% NOx, 24% CO2, non-st emissions, to improve the urban environment has a significant role in . A typical diesel engine and gasoline engine emissions and gas machine is shown in table l.
2, CNG vehicle for a higher security
Compared with gasoline, compressed natural gas is a relatively safe fuel.
(1) natural gas explosion limit is 5% higher than gasoline (lower explosion limit for the l%) high, methane ignition for 645 ℃, ignition than gasoline high 218 ℃, compared to not ignite. Low density of methane, the relative density of about 0.55, resulting in leakage of gas will soon be distributed in the air, in the case of the natural environment it is difficult to form a hot combustion conditions, once the compressed natural gas from the tank or pipe leaks, leak immediately surrounding the formation of low-temperature zone, so that the difficulties of natural gas combustion. Therefore is a fairly safe CNG motor fuel. Natural gas and fuel properties of gasoline is shown in table 2
(2) Department of natural gas vehicle cylinder pressure vessel
(20MPa), its materials and manufacture and testing in order that all States have strict control, in China there are "compressed natural gas cylinder vehicle standards)) (GBl7258-1998).
Cylinders fitted with explosion-proof facilities, pressure recer, valves and other equipment, strict standards high, and gas supply system is safe and reliable and will not tip over e to vehicle collision or cause fire or explosion, and the petrol tank of motor vehicles department of non-pressure vessels, fire easily after the explosion.
3, will help ease the contradiction between energy supply and demand tension.
China's economy is in a stage of rapid development, the number of vehicles to 1 million / year above the rate of increase of a substantial increase in gasoline demand of resources, our need to import large quantities of crude oil per year, refined oil and LPG. Optimize the use of gas cars
Motor fuel supply structure has changed only motor fuel gasoline, diesel patterns, not only eased the problem of shortage of petrol and transport services to meet the needs of the development.
4, extend engine life. The spread of natural gas to the gas entering the engine, the engine easily and uniformly mixed air, burning the comparison is totally clean; can improve the thermal cycle efficiency, speed up the burning speed, full use of combustion heat; CNG octane number at the same time high performance uprising, when agents do not need to add the uprising will not dilute the lubricating oil, making the parts inside the engine cylinder greatly rece wear and tear, so that the engine oil life and increase the use of the period. All of these vehicles will rece maintenance and operating costs, thereby enhancing the economy of the use of vehicles. 5, have a higher economic efficiency. At present, domestic gasoline prices continued to rise, the price system and the world has been the use of CNG vehicle will be able to save nearly 40% of fuel costs, as shown in table 3.
Third, CNG vehicle development prospects
CNG cars and filling stations will have broad prospects for development, mainly in the following aspects:
l, cars of the rapid growth of oil resources and environmental protection, the grim situation, the decision of the development of natural gas vehicles as a solution to energy issues and environmental issues an important way.
2, "Eleventh Five-Year" period, a new type of clean energy vehicles have been included in "long-term national science and technology development planning", the state will continue to organize and implement a variety of clean energy vehicles of major scientific and technological projects, the focus of support, including natural gas vehicles, including vehicles, parts, etc., will further promote the development of natural gas vehicle.
3, large-scale development of China's natural gas resources and pipeline construction to accelerate the pace of development of CNG and LPG filling stations make it possible. According to China's natural gas use planning, for nearly a decade, "West-East Gas Transmission", "second Shaanxi-Beijing", such as a large number of gas pipeline and gas pipeline along the cities have built large-scale use of natural gas in China's graal improvement of infrastructure, natural gas filling stations will graally form a network.
4, the development of CNG auto gas source with the stability of assurance to Tianjin as an example, at present, Tianjin has established a perfect system of natural gas transmission and distribution, from northern Shaanxi, Dagang, Tianjin, North China Oil Field to supply, gas supply is nearly mid-2005 600 million m3, 2006 was projected to reach 800 million m3, the length of pipe network 6894km, of which high-pressure pipeline 591km, for the "Eleventh Five-Year" period of Tianjin to develop large-scale construction of CNG filling stations car provides a guarantee.
Fourth, CNG cars and filling stations to explore the development of countermeasures
In order to speed up the use of natural gas as a clean fuel vehicle development, makes the following recommendations:
1, the Government has introced policies to encourage and support: the development of all countries in the world experience shows that government support is a necessary condition for accelerated development, the impact of its economic policy is an important factor in their development should be guaranteed in law, in the gas automobile proction, modification, parts and components proction, station construction, vehicle purchase and use of gas, maintenance and other aspects of pricing, taxation, investment, subsidies and other aspects of the preferential policies supporting. Gas prices affect gas vehicle development is an important factor, only the gas prices and gasoline prices when the difference is large enough to form, gas car before the development of an economic foundation and driving force.
2, strengthen leadership, the implementation of unified management.
The development of CNG vehicles to the construction of high-quality, convenient filling stations, the need for planning, public security, fire safety, labor, technical support supervisor and other departments.
3, in the municipal plan, filling stations and gas stations should be considered co-ordination, rational distribution and coordinated development. To make full use of existing land resources and in ensuring the environmental safety of oil and gas under the premise of building one station.
4, followed by motor cars and CNG filling stations in the simultaneous development of the principles, only in the stations into a network under the conditions, CNG vehicle can really develop. At the same time scale of only CNG car to a certain number, the normal operation of filling stations in order to achieve profitability.
5, the strict legal system: the development of stringent vehicle emissions regulations, and make sure that standards are not road vehicles are determined not to be on the qualifications of CNG vehicle Modify-Factroy critical examination, certification. First of all, the city should the city bus, taxi, as the focus of the development of CNG vehicle, bus stop some of the phenomenon of black smoke pollution of the environment.
6, step up publicity. At present, natural gas car is still at the initial stage, the public nature of its environmental protection, safety, economy, reliability, do not fully understand, so, it is necessary to carry out a wide range of social advocacy, efforts to increase awareness of the dangers of automobile exhaust, to make people aware of CNG is a clean, safe and economical fuel, so that the development of natural gas vehicles have been recognized by all sectors of society and support.
Compressed natural gas vehicles because of its remarkable economic and social benefits the development of the natural gas market will become a new field of applications. More and more importance in the environmental protection situation, along with natural gas resources in the area of the development and application of the widening, which will rece the environmental pressure is to ease the oil shortage and achieve sustainable development of a reliable guarantee.

3、求一篇关于汽车英语的文章
下面这篇文章将讲叙了世界，特别是中国、印度等国家的汽车行业的状况，联系了经济、燃油、环境等方面的问题，不知道能帮上你的忙吗？
Our Automobile Future
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 China. In India, there are about 11 cars per 1,000 eligible drivers. The comparison becomes interesting when you factor in cars in the United States. Kobert says that we have 1,114 automobiles per 1,000 eligible drivers. These figures help us understand why the United States is the top consumer of fossil fuels and emitter of carbon. 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 ratios. They are hungry for all of the amenities that are synonymous with a comfortable modern life and driving is one of them.
The urbanization of China has been dramatic over the past decade. Peasants have left the countryside for jobs in urban areas and the promise of a better life. As a result, urban areas have sprung up almost overnight to accommodate the boom in manufacturing. With a population if over 1 billion people, China has over 200 cities with at least 1 million people. As they increase their income, they will have expendable income that will allow them to purchase automobiles. The future looks bright for car sales in China and India. 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 day. If they were to match the number of United States drivers, they would need 200 million barrels of oil a day. 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 oil. This level of oil proction 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 rates.
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 e to the increase in fuel prices as we were heading into the Christmas holiday. Money spent on fuel is not money spent on the holiday. 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 warm. This comes at a time when utility companies are expanding the payment options for households and for many this includes credit cards.
As we look forward, a prudent person would understand that we are facing several enormous dilemmas. First of all, the world must drastically rece the amount of carbon we are releasing into the air. An increasing reliance on the internal combustion engine will obviously seal our fate. 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 vehicles. The average car stays on the road for 7 years. The hundreds of millions of vehicles on the road right now will be with us for years to come. As China and India add to their vehicle stock, it is likely that these vehicles will live out their life cycle as well.
Lastly, it is clear that if we continue to burn fossil fuels we will all be competing for a dwindling supply. The laws of economics tell us that prices will increase as demand outstrips supply. The future appears stark. The implications for increased military conflict to secure our energy future has already begun and will worsen as supply tightens.

Cars in America(美国的汽车)
Cars in America
Cars are an important part of life
in the United States. The car made the United
States
a
nation
on wheels.
And
it helped to make the United States what it is today.
There are three main reasons why the car became so popular in the United States. First of all the country is a huge one and Americans like to move around in it. The cars provide the most comfortable and cheapest form of transportation.
The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Nowadays there is a good system of air service provided by planes. But it is too expensive to be used frequently.
The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don't like to wait for a bus, or a train or even a plane. They don't like to have to follow an exact timetable.And the freedom a car gives them is what Americans want most to have.
The decrease of gas supplies has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas.
美国的汽车
汽车是美国生活的重要组成部分。汽车使得美国成为轮子上的国家，它也帮助美国成为现在的样子。
汽车在美国如此盛行有三个主要原因。首先这个国家地域辽阔，而美国人喜欢在其间来回走动。汽车提供了最舒适最便宜的交通方式。
汽车如此盛行的第二个原因是美国从未真正发展过有效廉价的公共交通这一事实。美国的长途火车从未像世界上其它地方那么普及。如今飞机提供了空中服务的良好体系。但是飞机太贵了，不能频繁使用。
而第三个原因是最为重要的。
美国人的独立精神是使得汽车盛行的真正原因。
美国人不喜欢等公共汽车、火车甚至飞机。他们不喜欢必须遵循精确的时间表。汽车给予他们的自由正是美国人最想得到的。
汽油供给的减少已经给美国人带来了巨大的问题。但答案不是发展更大型的公交体系。真正的解决方式必须是一种新型的汽车，那种不需要使用很多燃料的汽车。
Car Pollution
Each year there is an increasing number of cars on the roads as millions of new cars are proced. One out of six Americans works at making cars, driving trucks, building roads or filling up gas. Americans couldn't live without cars!
Most Americans would find it hard to imagine life without a car. However, some have realized the serious problem of air pollution caused by cars. The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted air is to make a car without pollution. But to build a clean car is easier said than done. Progress in this field is slow.
Another way is to replace car engines with something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model for us.
To prevent the world from being polluted by cars, we have to make some changes in our lives. Americans, for example, have to cut down on the number of their total cars.They are encouraged to use bicycles, which are thought to help keep the air clean.
But this change does not come easily. A large number of workers may find themselves without jobs if a car factory cioses down. Thus the problem of air pollution would become less important than that of unemployment. Although cars have led us to a better life, they have also brought us new problems.
汽车污染
上路的汽车数量逐年增长，同时，每年都会生产出几百万辆新车。在美国，每六个人中就有一个从事与汽车相关的工作：造车、开车、修路、加油等等。
离开汽车，美国人无法生活!
大部分美国人简直无法想象没有车的生活会是什么样子。但是一些人也已经意识到汽车造成的空气污染已成为严重的问题。被污染的空气具有毒性，并且危害健康。
解决空气污染的方法之一就是制造无污染汽车。但是生产清洁汽车说来容易做来难。
目前，这一领域的进展十分缓慢。
另一个方法就是使用其他东西替代汽车发动机。发明家正在研制蒸汽汽车和电车。但是许多厂家认为我们可以使用的实用型汽车的诞生可能还需要几年时间。
要想阻止全球化的汽车污染，我们需要对自己的生活方式做出适当的改变。例如，在美国，需要缩减汽车总量。鼓励人们使用有助空气清洁的自行车。
但这种改变不能一蹴而就。一旦汽车工厂关闭，就会有大量工人失去工作。与失业相比，空气污染似乎就不再那么重要了。尽管汽车为我们带来了更加舒适的生活，同时，它也带来了新的问题。

Today's diesels must meet the same emissions standards as gasoline vehicles, and advances in engine technologies, ultra-low sulfur diesel fuel, and improved exhaust treatment have made this possible.
Although emissions of particulates and smog-forming nitrogen oxides (NOx) are still relatively high, new "clean" diesel fuels, such as ultra-low sulfur diesel and biodiesel, and advances in emission control technologies will rece these pollutants also.
今天清洁的柴油,必须符合相同的排放标准,汽油车,先进的引擎技术, 超低硫柴油,并改进尾气处理有这个可能. 虽然排放的悬浮粒子和烟雾形成的氮氧化物( NOX )仍比较高,新的"干净"的柴油燃料相比, 如超低含硫量柴油,生物柴油和垫款在排放控制技术,可减少这些污染物也.
Hybrid-electric vehicles;
Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.
Some of the advanced technologies typically used by hybrids include混合电动车; 混合动力电动汽车(的HEV )结合的好处,汽油发动机和电动马达,可以通过配置来获取不同的目标,这种 作为提高燃油经济性,提高动力,或额外的辅助电源的电子设备和电动工具. 一些先进的技术,通常用杂交种包括:
Regenerative Braking. The electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted ring coasting and braking into electricity, which is stored in a battery until needed by the electric motor. 再生制动. 电动机电阻适用于传动造成车轮放慢了. 作为回报,能量从车轮转动马达,它的功能是一台发电机, 能源转换通常浪费在滑行和刹车成电力, 这是储存在电池直到所需的电机.
Electric Motor Drive/Assist. The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.
电机驱动/协助. 电动机提供额外的权力,以协助发动机在加速,超越,或爬山. 这使得规模较小,更加高效的引擎可以使用. 在一些车辆,电动机单独提供电源低速驾驶的情况下,内燃机是最有效的.
Automatic Start/Shutoff. Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.
自动启动/关机. 自动拒之门外引擎当汽车来停止并重新启动它时,油门被按下. 这样可避免浪费能源,从空转.
Flexible fuel vehicles (FFVs)
Flexible fuel vehicles (FFVs) are designed to run on gasoline or a blend of up to 85% ethanol (E85). Except for a few engine and fuel system modifications, they are identical to gasoline-only models.
FFVs have been proced since the 1980s, and dozens of models are currently available. Since FFVs look just like gasoline-only models, you may have an FFV and not even know it. To determine if your vehicle is an FFV, check the inside of your car's fuel filler door for an identification sticker or consult your owner’s manual.
灵活燃料汽车(FFVs)灵活燃料汽车(FFVs) ,设计运行于汽油或混合最多 85%乙醇( e85 ) . 除了少数的发动机和燃油系统的改装,它们是相同的汽油只有模型. 灵活燃料汽车已累计生产80年代以来,几十种型号,目前可用. 自灵活燃料汽车很像汽油唯一模式,你可以有一个新鲜水果和蔬菜,甚至不知道它. 确定如果你的汽车是一个新鲜水果和蔬菜, 检查内你的车子的加油口门上一贴,鉴定或请教你的车主手册.
FFVs experience no loss in performance when operating on E85. However, since a gallon of ethanol contains less energy than a gallon of gasoline, FFVs typically get about 20-30% fewer miles per gallon when fueled with E85.
灵活燃料汽车的经验,没有任何财物损失,在性能上经营e85 . 然而,由于一加仑乙醇含有更少的能源比一加仑汽油, 外国船队通常有约20-30%少英里每加仑,当燃用e85 .
Electric vehicles (EVs)
Electric vehicles (EVs) are propelled by an electric motor (or motors) powered by rechargeable battery packs. Electric motors have several advantages over internal combustion engines (ICEs): 电动车(电动车)电动车(电动车) ,发动机由电动机(或马达)提供动力的电池包. 电动马达拥有几项优势内燃机(考) :
Energy efficient. Electric motors convert 75% of the chemical energy from the batteries to power the wheels—internal combustion engines (ICEs) only convert 20% of the energy stored in gasoline.
Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant procing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants. 能源效率. 电动马达,将75%的化学能量从电池为电源的车轮-内燃机(考) ,只有转换 20%的能源储存汽油. 环保. 电动车不会排放废气污染物,虽然电厂生产的电力,排出的可能. 电力来自核,水能,太阳能,风能发电厂没有造成空气中的污染物.
Rece energy dependence. Electricity is a domestic energy source.
Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs.
The Down Side: Batteries
减少对能源的依赖. 电力是国内的能源来源. 性能优点. 电动马达提供安静,平稳操作和强大的加速度,需要的维修较少,比考. 弊:电池
EVs face significant battery-related challenges:
Driving range. Most EVs can only go 150 miles (or less) before recharging—gasoline vehicles can go over 300 miles before refueling.
Recharge time. Fully recharging the battery pack can take 4 to 8 hours.
Battery cost: The large battery packs are expensive and usually must be replaced one or more times.
Bulk & weight: Battery packs are heavy and take up considerable vehicle space.
Researchers are working on improved battery technologies to increase driving range and decrease recharging time, replacement frequency, weight, and cost. These factors will ultimately determine the future of EVs. 电动车面临着电池相关的挑战:练习场. 大部分电动车只能走150英里(或更少) ,然后充电汽油车辆可走300英里,然后加油. 充电时间. 完全充电的电池包可以采取4至8小时. 电池成本:大型电池盒十分昂贵,通常必须更换1次或更多次. 体积及重量:电池包重,并采取了相当多的车辆空间. 研究人员正在改进电池技术,以增加练习场和减少充电时间,更换频率,重量和成本. 这些因素最终决定自己前途的电动车.
