3 緒論近年來(lái),中國(guó)國(guó)民經(jīng)濟(jì)取得了持續(xù)快速發(fā)展,隨之而來(lái)的是環(huán)境污染形勢(shì)越來(lái)越嚴(yán)峻。為從根本上提高機(jī)動(dòng)車排放水平,控制城市機(jī)動(dòng)車排放污染,改善城市空氣質(zhì)量,學(xué)習(xí)和借鑒國(guó)外先進(jìn)技術(shù)和經(jīng)驗(yàn),研究制定適合中國(guó)國(guó)情的“清潔汽車技術(shù)路徑”及配套的政策、標(biāo)準(zhǔn)和法規(guī)體系,并由政府主導(dǎo)實(shí)施,這是至關(guān)重要的。這些燃料的排放的污染物成本要比汽油和柴油低,代替汽油和柴油的燃料前景是很廣闊的。壓縮天然氣(CNG)和液化石油氣(LPG)二種。 甘肅畜牧工程職業(yè)技術(shù)學(xué)院畢 業(yè) 論 文洽談汽車代用燃料系 別:車輛工程系專 業(yè):汽車檢測(cè)與維修班 級(jí):學(xué)生姓名:馬治國(guó)指導(dǎo)老師:劉 英完成時(shí)間:2011年10月10日目 錄摘 要...........................................................2 Take to.............................................................31 緒論..............................................................41.1世界汽車、能源及環(huán)境概況......................................41.2中國(guó)汽車、能源及環(huán)境概況......................................42各類燃料汽車技術(shù)發(fā)展?fàn)顩r分析...................................... 42.1燃?xì)馄?LPG汽車和CNG汽車) ................................ 52.2 醇類燃料(甲醇、乙醇)汽車 .................................. 10 3 各類燃料汽車的環(huán)境和能源效益分析.................................123.1 LPG汽車 ....................................................123.2 CNG汽車.....................................................143.3醇類汽車的排放控制水平.......................................153.4混合動(dòng)力汽車的排放控制水平...................................164 中國(guó)燃料汽車技術(shù)發(fā)展路徑.........................................174.1 技術(shù)發(fā)展路徑 ............................................. 185 結(jié)論和展望 .....................................................19致 謝.........................................................20參考文獻(xiàn).........................................................21 1 摘 要本文重點(diǎn)介幾種汽車代用燃料,主要有壓縮天然氣(CNG)、液化石油氣(LPG)、醇類(甲醇和乙醇),通過(guò)對(duì)這幾種汽車代用燃料的特點(diǎn)、性質(zhì)和燃料的清潔做了詳細(xì)的介紹。液化石油可降低co2排放,減少溫室效應(yīng)。其化學(xué)性質(zhì)較穩(wěn)定,可燃成分高、熱值高、辛烷值高,抗爆性好、著火范圍廣,有利于稀燃燒技術(shù)的應(yīng)用。汽車行動(dòng)是一項(xiàng)長(zhǎng)期而復(fù)雜的系統(tǒng)工程,治標(biāo)必治本。[關(guān)鍵詞]:新能源、汽車、CNG、LPG、前景 2 Take toThis article focus mediated several alternative automobile fuels, mainly with pressed natural gas ( CNG ), liquefied petroleum gas ( LPG ), alcohols ( methanol and ethanol ), based on which several automobile alternate fuel characteristics, nature and fuel cleaner is introduced in detail. Liquefied oil can reduce the CO2 emissions, reduce the greenhouse effect. Compressed natural gas ( CNG ) and liquefied petroleum gas ( LPG ) two. The chemical properties of a more stable, high bustible ponents, high calorific value, high octane number, good antiknock property, fire range is wide, in favor of lean bustion technology application. These fuel emissions than gasoline and diesel with low cost, instead of gasoline and diesel fuel prospect is very broad. Auto operation i
