style="text-indent:25px">為了保證柴油機(jī)正常工作，在氣溫允許的情況下，可盡量選用高凝點(diǎn)的柴油。其目的，是可提高經(jīng)濟(jì)效益。為此，通常選用柴油凝點(diǎn)比當(dāng)?shù)剌^低氣溫低5℃左右即可。例如環(huán)境溫度在4~7℃以上時，選購O號規(guī)格的柴油是以能保證柴油機(jī)正常使用。同樣道理，-10號輕柴油適用于較低氣溫在-5℃以上的地區(qū)使用。不同牌號的輕柴油,由于它們的性能指標(biāo)除凝點(diǎn)以外，都基本相同。因此用油單位在容器不足的情況下，可以混合使用，并不影響其質(zhì)量。但是，此時必須以凝點(diǎn)較高的柴油，作為使用基準(zhǔn)。否則，將因不適合當(dāng)?shù)丨h(huán)境溫度，使柴油機(jī)無法正常工作。武漢標(biāo)準(zhǔn)0#柴油柴油的需求量增長速度是大于汽油的。</p><div

style="text-indent:25px">一般選用柴油的凝點(diǎn)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(diǎn)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(diǎn)。與凝點(diǎn)相比，它更能反映實際使用性能。對同一油品，一般冷濾點(diǎn)比凝點(diǎn)高1℃～3℃。采用脫蠟的方法，可降低凝點(diǎn)，得到低凝柴油。高速柴油機(jī)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(diǎn)（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。</p><p style="text-indent:25px">說起柴油大家都不陌生，它是啟動車的原液，柴油的注意點(diǎn)有哪些？柴油的注意點(diǎn)有：儲存柴油的容器要保持清潔，無雜質(zhì)、雨水等，在使用之前應(yīng)該對盛裝器皿做底部清理工作，避免柴油被污染。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(jī)燃料供給系統(tǒng)的正常工作。柴油嚴(yán)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(jìn)行必要的預(yù)熱。柴油要防止水份、機(jī)械雜質(zhì)混入。柴油嚴(yán)禁與汽油混合后用于照明或作煤油爐燃料。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。</p><div
