【正文】 d electric cars bring us infinite joy will give us the physical and mental relaxation. Take for example, automatic transmission in road, can not on the clutch, can achieve automatic shift and engine flameout, not so effective improve the driving convenience lighten the fatigue strength. Automatic transmission consists mainly of hydraulic torque converter, gear transmission, pump, hydraulic control system, electronic control system and oil cooling system, etc. The electronic control of suspension is mainly used to cushion the impact of the body and the road to reduce vibration that car getting smoothgoing and stability. When the vehicle in the car when the road uneven road can according to automatically adjust the height. When the car ratio of height, low set to gas or oil cylinder filling or oil. If is opposite, gas or diarrhea. To ensure and improve the level of driving cars driving stability. Variable force power steering system can significantly 第 2 頁 change the driver for the work efficiency and the state, so widely used in electric cars. VDC to vehicle performance has important function it can according to the need of active braking to change the wheels of the car, car motions of state and optimum control performance, and increased automobile adhesion, controlling and stability. Besides these, appear beyond 4WS 4WD electric cars can greatly improve the performance of the value and ascending simultaneously. ABS braking distance is reduced and can keep turning skills effectively improve the stability of the directions simultaneously reduce tyre wear. The airbag appear in large programs protected the driver and passenger39。s safety, and greatly reduce automobile in collision of drivers and passengers in the buffer, to protect the safety of life. Intelligent electronic technology in the bus to promote safe driving and that the other functions. The realization of automatic driving through various sensors. Except some smart cars equipped with multiple outside sensors can fully perception of information and traffic facilities and to judge whether the vehicles and drivers in danger, has the independent pathfinding, navigation, avoid bump, no parking fees etc. Function. Effectively improve the safe transport of manipulation, reduce the pilot fatigue, improve passenger fort. Of course battery electric vehicle is the key, the electric car battery mainly has: the use of leadacid batteries, nickel cadmium battery, the battery, sodium sulfide sodium sulfide lithium battery, the battery, the battery, the flywheel zinc air fuel cell and solar battery, the battery. In many kind of cells, the fuel cell is by far the most want to solve the problem of energy shortage car. Fuel cells have high pollution characteristics, different from other battery, the battery, need not only external constantly supply of fuel and electricity can continuously steadily. Fuel cell vehicles (FCEV) can be matched with the car engine performance and fuel economy and emission in the aspects of superior internalbustion vehicles. Along with the puter and electronic product constantly upgrading electric car, open class in mature technology and perfected, that drive more safe, convenient and flexible, fortable. Now, the electric car from ordinary consumers distance is still very far away, only a few people in bandwagon. Electric cars with traditional to pete in the market, the car will was electric cars and intelligent car replaced. This is the question that day after timing will e. ABS, GPS, and various new 4WD 4WS, electronic products and the modern era, excellent performance auto tacit understanding is tiein, bring us unparalleled precision driving fort and safety of driving. 第 3 頁 隨著世界能源危機(jī)的持續(xù)，以及戰(zhàn)爭和能源 石油的消耗及汽車飽有量的增加，能源在一天一天下降，終有一天它會消失的無影無蹤。所以必須在石油耗凈之前找到一種代替品。電動汽車將成為人們最為理想的交通工具。電子控制技術(shù)在汽車上得到了廣泛應(yīng)用，汽車上應(yīng)用的電子裝置越來越豐富，電子技術(shù)不僅用來改善和提高傳統(tǒng)汽車電器的質(zhì)量和性能，而且還提高了汽車的動力性、燃油經(jīng)濟(jì)性、可靠性以及廢氣排放的凈化性。從發(fā)動機(jī)的燃油噴射點(diǎn)火裝置、進(jìn)氣控制、廢氣排放控制、故障自診斷到車身輔助裝置都普遍采用了電子控制技術(shù)，可以說今后汽車發(fā)展主要以機(jī)電一體化。有了這些系統(tǒng)汽車響應(yīng)敏捷，使用功能強(qiáng)，可靠性高，既保證發(fā)動機(jī)動力又降低燃油的消耗，而且又滿足排放法規(guī)的標(biāo)準(zhǔn)。而電動汽車給我們帶來無限樂趣外還能給我們勞累一天的身心得以放松。自動變速器主要由液力變矩器、齒輪變速器、油泵、液壓控制系統(tǒng)、電子控制系統(tǒng)、油冷卻系統(tǒng)等組成。當(dāng)汽車行駛在不平坦的道路時(shí)汽車能能根據(jù)底盤和路面高度自動調(diào)整。如果是相反，就放氣或?yàn)a油?？勺兞恿D(zhuǎn)向系統(tǒng)因能顯著改變駕駛員的工作效率和狀態(tài)，所以在電動汽車上廣泛使用。除了這些之外 4WS、 4WD 的出現(xiàn)大大提高了電動汽車的價(jià)值與性能同步提升。安全氣囊的出現(xiàn)在很大程序上保護(hù)了駕駛員和乘客的安全，大大降低汽車在碰撞時(shí)對駕駛員和乘客的緩沖，以過到保護(hù)生命安全的目的。通過 各種傳感器實(shí)現(xiàn)自動駕駛。有效提高運(yùn)輸過程中的安全，減少駕駛員的 第 4 頁 操縱疲勞度，提高乘客的舒適度。在諸多種電池中，燃料電池是迄今為止最有希望解決汽車能源短缺問題的動力源。燃料電池汽車 (FCEV)具有可與內(nèi)燃機(jī)汽車媲美的動力性能，在排放、燃油經(jīng)濟(jì)性方面明顯優(yōu)于內(nèi)燃機(jī)車輛。現(xiàn)在，電動汽車離普通消費(fèi)者的距離還很遙遠(yuǎn)，只有少數(shù)人在趕趕時(shí)髦而已。這只是時(shí)間性的問題這一天終究會來到的。 第 5 頁 摘 要：本文闡述了發(fā)展壓縮天然氣汽車 (CNG)的環(huán)保低污染性、安全性、經(jīng)濟(jì)性及 CNG 汽車和加氣站的發(fā)展前景及對策。壓縮天然氣汽車 (CNG)以其能耗低、污染物排放量小而受到各國的歡迎，是國際公認(rèn)
