一、車用尿素有什么用
車(che)用(yong)(yong)(yong)(yong)(yong)(yong)尿(niao)素(su)(su)是柴(chai)(chai)油車(che)使用(yong)(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)，用(yong)(yong)(yong)(yong)(yong)(yong)于處理凈(jing)化(hua)(hua)柴(chai)(chai)油機尾氣的(de)(de)(de)車(che)用(yong)(yong)(yong)(yong)(yong)(yong)品(pin)，是SCR方案的(de)(de)(de)必需添加(jia)劑，一般由百分(fen)之32.5的(de)(de)(de)高純(chun)尿(niao)素(su)(su)和百分(fen)之67.5的(de)(de)(de)去離子水組(zu)成(cheng)。車(che)用(yong)(yong)(yong)(yong)(yong)(yong)尿(niao)素(su)(su)的(de)(de)(de)用(yong)(yong)(yong)(yong)(yong)(yong)途主要有(you)：1、在車(che)輛(liang)中主要起到凈(jing)化(hua)(hua)尾氣的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)(yong)，能與尾氣中的(de)(de)(de)氮氧化(hua)(hua)物(wu)發生反應(ying)，將尾氣中的(de)(de)(de)氮氧化(hua)(hua)合(he)物(wu)（NOx）催化(hua)(hua)還原成(cheng)無害的(de)(de)(de)氮氣（N2）和水（H?O）排出，減少氮氧化(hua)(hua)物(wu)排放，現在對重型(xing)卡(ka)客車(che)尾氣的(de)(de)(de)檢測(ce)越來越多嚴(yan)格，不用(yong)(yong)(yong)(yong)(yong)(yong)車(che)用(yong)(yong)(yong)(yong)(yong)(yong)尿(niao)素(su)(su)就(jiu)不達標。2、車(che)用(yong)(yong)(yong)(yong)(yong)(yong)尿(niao)素(su)(su)還有(you)一個(ge)用(yong)(yong)(yong)(yong)(yong)(yong)途，那(nei)就(jiu)是能優化(hua)(hua)發動機性能和燃料消(xiao)(xiao)耗，減少柴(chai)(chai)油消(xiao)(xiao)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)尿素(su)(su)是(shi)指濃度為32.5%且(qie)溶劑(ji)為超(chao)純水(shui)的尿素(su)(su)水(shui)溶液，生(sheng)產原(yuan)料為車用(yong)尿素(su)(su)專用(yong)原(yuan)料和超(chao)純水(shui)，它進入汽車內部后，通(tong)過尿素(su)(su)罐噴(pen)(pen)射系統，噴(pen)(pen)射于汽車排(pai)氣管(guan)發生(sheng)反(fan)應；排(pai)氣管(guan)上(shang)安裝(zhuang)有尿素(su)(su)計量噴(pen)(pen)射裝(zhuang)置(zhi)，在溫度達到300℃-500℃時(shi)自(zi)動噴(pen)(pen)入尿素(su)(su)溶液，在催(cui)化劑(ji)的作(zuo)用(yong)下(xia)尿素(su)(su)（NH2CONH2）水(shui)解產生(sheng)NH3和CO2，NH3與NOx反(fan)應，生(sheng)成氮氣和水(shui)排(pai)出(chu)，起到凈化尾氣的作(zuo)用(yong)。
