style="text-indent:25px">怎么分辨柴油和汽油？1.汽油具有很強(qiáng)的揮發(fā)性，而柴油很難揮發(fā)，因此汽油車污染物中有燃料蒸發(fā)排放物，其組分是碳?xì)浠衔?HC)。2.汽油具有容易與空氣混合，且混合后不易分離的特性。汽油與空氣可以混合得很均勻，基本不存在局部過濃或過稀和液態(tài)油滴的情況。汽油的分子較小。柴油與空氣的混合是不均勻的，不可避免地存在局部缺氧或局部富氧情況。油料在高溫缺氧時(shí)，易炭化形成炭煙。柴油燃燒后會(huì)生成一些有臭味的有機(jī)氣體，因此，柴油機(jī)排放中還有臭味。3.兩者在化學(xué)方面的區(qū)別:汽油中的碳原子較少，為8-10個(gè)，柴油為12-15，所以柴油蘊(yùn)涵的能量較高。柴油不用點(diǎn)火，在較高的壓力下自燃，所以它的效率較高(其實(shí)較高利用率不過30%)，***柴油報(bào)價(jià)，但是它十分的笨重，噪音又大。汽油需要點(diǎn)火，所以汽油機(jī)的體積較小，也很安靜(其利用率才不過15%)。4.味道不一樣，汽油刺鼻，柴油味淡，***柴油報(bào)價(jià)。顏色不一樣，汽油淡色，柴油深色。容度不一樣，汽油較稀.柴油較濃。在交通工具上點(diǎn)燃方式不一樣，汽油是火花塞點(diǎn)燃，***柴油報(bào)價(jià)，柴油是壓燃。柴油的抗爆性較差。柴油較汽油馬力小、污染重、冒黑煙，但價(jià)格低。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。***柴油報(bào)價(jià)</p><div

style="text-indent:25px">柴油的沸點(diǎn)范圍和黏度介于煤油與潤(rùn)滑油之間的液態(tài)石油餾分。易燃易揮發(fā)，不溶于水，易溶于醇和其他有機(jī)溶劑。是組分復(fù)雜的混合物，沸點(diǎn)范圍有180℃～370℃和350℃～410℃兩類。沸點(diǎn)范圍和黏度介于煤油與潤(rùn)滑油之間的液態(tài)石油餾分。主要指標(biāo)是十六烷值、黏度、凝固點(diǎn)等。對(duì)柴油質(zhì)量要求是燃燒性能和流動(dòng)性好。燃燒性能用十六烷值表示愈高愈好，大慶原油制成的柴油十六烷值可達(dá)68。高速柴油機(jī)用的輕柴油十六烷值為42～55，低速的在35以下。佛山0號(hào)發(fā)電機(jī)柴油現(xiàn)價(jià)柴油用做轉(zhuǎn)速不低于960r/min的壓燃式高速柴油發(fā)動(dòng)機(jī)的燃料，也可用做各種柴油燃燒器的燃料。</p><div

style="text-indent:25px">在柴油中十六烷值是指柴油的燃燒性能相當(dāng)于十六烷與a-甲基萘混合液中，十六烷所占的容積百分?jǐn)?shù).十六烷的燃燒性質(zhì)和起動(dòng)性質(zhì)均比a-甲基萘要好得多。假設(shè)十六烷的燃燒性能是100個(gè)單位，a-甲基萘是0個(gè)單位。把這兩種燃燒性能不同的物質(zhì)，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(biāo)準(zhǔn)柴油。例如，0號(hào)輕柴油規(guī)定十六烷值不應(yīng)小于50，就表示它的燃燒性能相當(dāng)于50%十六烷與50%a-甲基萘的混合液。十六烷值越大,燃燒性能也越好。工程機(jī)械柴油機(jī)用的輕柴油，十六烷值一般在45—60為好。十六烷值過低，會(huì)引起柴油機(jī)工作粗暴，冬季起動(dòng)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(jī)排氣冒黑煙，功率下降和油耗增加。</p><p style="text-indent:25px">凝點(diǎn)是評(píng)定柴油流動(dòng)性的重要指標(biāo)，它表示燃料不經(jīng)加熱而能輸送的較低溫度。柴油的凝點(diǎn)是指油品在規(guī)定條件下冷卻至喪失流動(dòng)性時(shí)的較高溫度。柴油中正構(gòu)烷烴含量多且沸點(diǎn)高時(shí)，凝點(diǎn)也高。一般選用柴油要求凝點(diǎn)低于環(huán)境溫度3～5℃。因此，隨季節(jié)和地區(qū)的變化，可使用不同牌號(hào)（不同凝點(diǎn)）的商品柴油。在實(shí)際使用中，柴油在低溫下會(huì)析出結(jié)晶體，晶體長(zhǎng)大到一定程度就會(huì)堵塞濾網(wǎng)，這時(shí)的溫度稱作冷濾點(diǎn)。與凝點(diǎn)相比，它更能反映實(shí)際使用性能。對(duì)同一油品，一般冷濾點(diǎn)比凝點(diǎn)高1～3℃。采用脫蠟的方法，可得到低凝柴油。柴油分為輕柴油和重柴油兩大類。</p><div
