style="text-indent:25px">在柴油中十六烷值是指柴油的燃燒性能相當于十六烷與a-甲基萘混合液中，武漢0#柴油，十六烷所占的容積百分數(shù).十六烷的燃燒性質(zhì)和起動性質(zhì)均比a-甲基萘要好得多。假設十六烷的燃燒性能是100個單位，a-甲基萘是0個單位。把這兩種燃燒性能不同的物質(zhì)，武漢0#柴油，按不同的容積比配合成混合溶液,就可得到十六烷值從0到100的各種標準柴油。例如，0號輕柴油規(guī)定十六烷值不應小于50，就表示它的燃燒性能相當于50%十六烷與50%a-甲基萘的混合液，武漢0#柴油。十六烷值越大,燃燒性能也越好。工程機械柴油機用的輕柴油，十六烷值一般在45—60為好。十六烷值過低，會引起柴油機工作粗暴，冬季起動困難。十六烷值過高，噴人燃燒室的柴油來不及與空氣充分混合就已著火，致使燃燒不完全,造成柴油機排氣冒黑煙，功率下降和油耗增加。根據(jù)密度的不同，對石油及其加工產(chǎn)品，習慣上對沸點或沸點范圍低的稱為輕，相反成為重。武漢0#柴油</p><div

style="text-indent:25px">凝點是評定柴油流動性的重要指標，它表示燃料不經(jīng)加熱而能輸送的較低溫度。柴油的凝點是指油品在規(guī)定條件下冷卻至喪失流動性時的較高溫度。柴油中正構烷烴含量多且沸點高時，凝點也高。一般選用柴油要求凝點低于環(huán)境溫度3～5℃。因此，隨季節(jié)和地區(qū)的變化，可使用不同牌號（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，可得到低凝柴油。</p><p style="text-indent:25px">目前國內(nèi)應用的輕柴油按凝固點分為6個牌號：10#柴油、0#柴油、-10#柴油、-20#柴油、-35#柴油和-50#柴油。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；溫度在-29℃-----44℃時選用-50#柴油。選用柴油的牌號如果低于上述溫度，發(fā)動機中的燃油系統(tǒng)就可能結蠟，堵塞油路，影響發(fā)動機的正常工作。輕柴油的牌號是按其凝點的高低來區(qū)分的。</p><div

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。國標0號柴油含硫量低，不腐蝕發(fā)電機部件。高性能0#柴油多少錢一升</p><p style="text-indent:25px">輕柴油是各種高速、中速柴油發(fā)動機（柴油機）的燃料。武漢0#柴油</p><p style="text-indent:25px">柴油的儲存與使用：1、防止水份、機械雜質(zhì)混入。2、嚴禁與汽油混合后用于照明或作煤油爐燃料。3、柴油在使用前都須經(jīng)過沉淀、過濾、除去雜質(zhì)和水份，以保證柴油機燃料供給系統(tǒng)的正常工作。4、低溫時，為改善柴油的低溫流動性，允許在柴油中滲入少量煤油，但閃點可能不合格。但決不允許在柴油中加入汽油來改善柴油的低溫流動性。5、同一級別牌號不同的柴油，由于它們的質(zhì)量指標除凝點和冷濾點外基本相同，所以當資源不足時，可以在合適氣溫用油情況下混用。6、嚴防曝曬及明火加熱，盡量在較低溫度下儲存。冬季在使用柴油時可進行必要的預熱。武漢0#柴油</p><p
