一、車用尿素有什么用
車用(yong)(yong)(yong)尿(niao)素(su)是柴油車使用(yong)(yong)(yong)的(de)(de)(de)，用(yong)(yong)(yong)于處(chu)理凈化(hua)柴油機尾(wei)(wei)氣(qi)(qi)的(de)(de)(de)車用(yong)(yong)(yong)品(pin)，是SCR方案的(de)(de)(de)必(bi)需(xu)添加(jia)劑，一(yi)般由百分之(zhi)32.5的(de)(de)(de)高純尿(niao)素(su)和(he)百分之(zhi)67.5的(de)(de)(de)去離子水組成。車用(yong)(yong)(yong)尿(niao)素(su)的(de)(de)(de)用(yong)(yong)(yong)途主要(yao)有：1、在(zai)車輛中(zhong)(zhong)主要(yao)起(qi)到(dao)凈化(hua)尾(wei)(wei)氣(qi)(qi)的(de)(de)(de)作用(yong)(yong)(yong)，能(neng)與尾(wei)(wei)氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)氮(dan)(dan)氧化(hua)物發(fa)(fa)生(sheng)反應，將尾(wei)(wei)氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)氮(dan)(dan)氧化(hua)合(he)物（NOx）催化(hua)還原成無(wu)害的(de)(de)(de)氮(dan)(dan)氣(qi)(qi)（N2）和(he)水（H?O）排出，減少(shao)氮(dan)(dan)氧化(hua)物排放，現在(zai)對重型卡客車尾(wei)(wei)氣(qi)(qi)的(de)(de)(de)檢測越來越多嚴格，不(bu)用(yong)(yong)(yong)車用(yong)(yong)(yong)尿(niao)素(su)就不(bu)達標。2、車用(yong)(yong)(yong)尿(niao)素(su)還有一(yi)個用(yong)(yong)(yong)途，那就是能(neng)優化(hua)發(fa)(fa)動(dong)機性能(neng)和(he)燃料消耗，減少(shao)柴油消耗量可達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
車用尿(niao)(niao)(niao)素(su)是指濃(nong)度為32.5%且(qie)溶劑為超(chao)純(chun)水(shui)(shui)的(de)尿(niao)(niao)(niao)素(su)水(shui)(shui)溶液，生(sheng)產原(yuan)料為車用尿(niao)(niao)(niao)素(su)專(zhuan)用原(yuan)料和(he)(he)(he)超(chao)純(chun)水(shui)(shui)，它進入汽車內部后，通過尿(niao)(niao)(niao)素(su)罐噴(pen)射系統，噴(pen)射于汽車排氣(qi)管發生(sheng)反應；排氣(qi)管上安(an)裝有(you)尿(niao)(niao)(niao)素(su)計量噴(pen)射裝置，在溫度達到300℃-500℃時自動(dong)噴(pen)入尿(niao)(niao)(niao)素(su)溶液，在催化(hua)劑的(de)作(zuo)用下尿(niao)(niao)(niao)素(su)（NH2CONH2）水(shui)(shui)解產生(sheng)NH3和(he)(he)(he)CO2，NH3與NOx反應，生(sheng)成(cheng)氮氣(qi)和(he)(he)(he)水(shui)(shui)排出(chu)，起到凈化(hua)尾(wei)氣(qi)的(de)作(zuo)用。
