style="text-indent:25px">柴油質(zhì)量的鑒別方法：1.若發(fā)現(xiàn)0號柴油渾濁或黑色、無色時，多為不合格。2.測密度。常溫下，0號柴油的比重為0.82---0.85左右，若密度太高，則說明該柴油干點過高，發(fā)動機在正常工作過程中容易燃燒不完、冒黑煙、積碳；若太低，則說明該柴油的低碳成分過多，機械正常工作過程容易產(chǎn)生爆震、機械加速無力或閃點過低?？梢酝ㄟ^密度計檢測，或在使用過程中發(fā)現(xiàn)上述現(xiàn)象時，可以初步判別該柴油質(zhì)量有問題。3.測閃點。閃點是衡量柴油著火危險性的指標，閃點越低，則發(fā)生著火的危險性越大。合格的0號柴油，國家標準要求的閃點為55℃（閉口），然而，只要向其混入一小部分低沸點烴，其沸點就會驟然下降，特別敏感。因此，若有條件可以用閃點儀測量，簡單方便；若無條件，可以取少許柴油，敞口在太陽下，閃點較低時，可以看到油品揮發(fā)出來的大量煙氣。岳陽標準0#柴油生產(chǎn)廠家0號柴油指凝點是0攝氏度，即在低于0度時油品就會發(fā)生凝固的現(xiàn)象。</p><div

style="text-indent:25px">柴油的主要性能：輕柴油是各種高速、中速柴油發(fā)動機（柴油機）的燃料。柴油發(fā)動機不是由火花塞點火燃燒，而是柴油經(jīng)過噴嘴霧化，與空氣混合，壓縮自燃著火的，因此又稱為壓燃式發(fā)動機。柴油發(fā)動機由于具有熱效率高、耗油低及燃料火災(zāi)危險性小等特點，普遍應(yīng)用于汽車，艦艇，拖拉機，坦克等大型航運設(shè)備中。通常，輕柴油的牌號是按其凝點的高低來區(qū)分的。0號輕柴油表示其凝點不高于0oC，正20號農(nóng)用柴油表示其凝點不高于+20oC，柴油的燃燒性能好。</p><p style="text-indent:25px">一般選用柴油的凝點低于環(huán)境溫度3℃～5℃，因此，隨季節(jié)和地區(qū)的變化，需使用不同牌號，即不同凝點的商品柴油。在實際使用中，柴油在低溫下會析出結(jié)晶體，晶體長大到一定程度就會堵塞濾網(wǎng)，這時的溫度稱作冷濾點。與凝點相比，它更能反映實際使用性能。對同一油品，一般冷濾點比凝點高1℃～3℃。采用脫蠟的方法，可降低凝點，得到低凝柴油。高速柴油機要求柴油噴入燃燒室后迅速與空氣形成均勻的混合氣，并立即自動著火燃燒，因此要求燃料易于自燃。從燃料開始噴入氣缸到開始著火的間隔時間稱為滯燃期或著火落后期。燃料的自燃點（在空氣存在下能自動著火的溫度）低，則滯燃期短，即著火性能好。0#柴油中0#指的是是一個標號，表達這種柴油的型號。</p><div

style="text-indent:25px">0號柴油和國五柴油的區(qū)別：1、使用范圍不同：0號柴油屬于重柴油，轉(zhuǎn)速越低，選用的重柴油凝點越高。用于農(nóng)田排灌、漁輪、船舶等，也用作鍋爐燃料；國五柴油屬于輕柴油，普遍用于柴油汽車、拖拉機以及配用于船舶、礦山、發(fā)電、鉆井等設(shè)備的高速柴油發(fā)動機燃料。2、物理特性不同：重柴油質(zhì)量要求較寬，十六烷值較低，粘度較大、凝固點較高。為黃色、易燃液體，粘度適宜，噴油霧化優(yōu)良化；輕柴油質(zhì)量要求較嚴，十六烷值較高，粘度較小，凝固點和含硫量較低。3、獲得方式不同：重柴油密度較大，由天然石油、人造石油等經(jīng)分餾或裂化而得；輕柴油密度相對較輕，180——370℃餾分，由天然石油的直餾柴油與二次加工柴油摻合而得，有時也摻入一部分裂化產(chǎn)物。柴油的燃燒性好是指噴入燃燒室內(nèi)與高溫空氣形成均勻的可燃混合氣之后，在較短的時間內(nèi)發(fā)火自燃并完全燃燒。標準0#柴油多少錢一升</p><p style="text-indent:25px">柴油具有低能耗、低污染的環(huán)保特性，所以一些小型汽車甚至高性能汽車也改用柴油。標準柴油采購</p><p style="text-indent:25px">選用柴油的依據(jù)是使用時的溫度。柴油汽車主要選用后5個牌號的柴油，溫度在4℃以上時選用0#柴油；溫度在4℃-----5℃時選用-10#柴油；溫度在-5℃-----14℃時選用-20#柴油；溫度在-14℃-----29℃時選用-35#柴油；選用柴油的牌號如果高于上述溫度，發(fā)動機中的燃油系統(tǒng)就可能結(jié)蠟，堵塞油路，影響發(fā)動機的正常工作。高速柴油機（汽車用）比汽油機省油，柴油需求量增長速度大于汽油。柴油機較汽油機熱效率高，功率大，燃料單耗低，比較經(jīng)濟，故應(yīng)用日趨普遍。標準柴油采購</p><p
