一、車用尿素有什么用
車(che)用(yong)(yong)尿素(su)(su)是(shi)(shi)柴(chai)(chai)油(you)車(che)使用(yong)(yong)的(de)，用(yong)(yong)于處(chu)理凈化(hua)柴(chai)(chai)油(you)機尾氣(qi)(qi)的(de)車(che)用(yong)(yong)品，是(shi)(shi)SCR方(fang)案(an)的(de)必需添加劑，一般由(you)百(bai)分之32.5的(de)高純尿素(su)(su)和(he)百(bai)分之67.5的(de)去離子水組成。車(che)用(yong)(yong)尿素(su)(su)的(de)用(yong)(yong)途(tu)主要有：1、在車(che)輛中(zhong)主要起到凈化(hua)尾氣(qi)(qi)的(de)作用(yong)(yong)，能與尾氣(qi)(qi)中(zhong)的(de)氮(dan)氧(yang)化(hua)物(wu)發(fa)生(sheng)反(fan)應(ying)，將(jiang)尾氣(qi)(qi)中(zhong)的(de)氮(dan)氧(yang)化(hua)合物(wu)（NOx）催化(hua)還原成無害的(de)氮(dan)氣(qi)(qi)（N2）和(he)水（H?O）排(pai)出，減少氮(dan)氧(yang)化(hua)物(wu)排(pai)放，現在對重型卡(ka)客車(che)尾氣(qi)(qi)的(de)檢測(ce)越來(lai)越多嚴(yan)格，不用(yong)(yong)車(che)用(yong)(yong)尿素(su)(su)就不達標。2、車(che)用(yong)(yong)尿素(su)(su)還有一個用(yong)(yong)途(tu)，那就是(shi)(shi)能優(you)化(hua)發(fa)動機性能和(he)燃料(liao)消耗，減少柴(chai)(chai)油(you)消耗量可達5-7%。

三、車用尿素液配方與制作方法
1、配方：（1）普通型尿素溶液配方比例：高純尿素32.5%、去離子水67.5%。（2）防凍型尿素溶液配方比例：高純尿素32.5%、去離子水52.5%、甲醇15%。2、制作方法：將32.5%的高純尿素和67.5%的高純水進行混配，就可以得到車用尿素液體。自制車用尿素液比較麻煩，而且不一定能保證純度和雜質含量，因此還是建議大家通過正規渠道購買優質車用尿素品牌的產品。

五、車用尿素是什么原理
車用(yong)(yong)尿(niao)素是指濃度為(wei)32.5%且溶(rong)(rong)劑(ji)為(wei)超(chao)純水(shui)的尿(niao)素水(shui)溶(rong)(rong)液，生產原料(liao)為(wei)車用(yong)(yong)尿(niao)素專用(yong)(yong)原料(liao)和超(chao)純水(shui)，它(ta)進入汽車內部后，通過尿(niao)素罐噴(pen)射系統，噴(pen)射于(yu)汽車排氣(qi)(qi)管發(fa)生反(fan)應(ying)；排氣(qi)(qi)管上安裝有尿(niao)素計量噴(pen)射裝置，在(zai)溫(wen)度達到300℃-500℃時自動噴(pen)入尿(niao)素溶(rong)(rong)液，在(zai)催化(hua)劑(ji)的作(zuo)用(yong)(yong)下尿(niao)素（NH2CONH2）水(shui)解產生NH3和CO2，NH3與NOx反(fan)應(ying)，生成(cheng)氮氣(qi)(qi)和水(shui)排出(chu)，起到凈化(hua)尾(wei)氣(qi)(qi)的作(zuo)用(yong)(yong)。
