一、車用尿素有什么用
車(che)用(yong)尿素是柴(chai)(chai)油車(che)使用(yong)的(de)(de)，用(yong)于處理(li)凈(jing)化(hua)(hua)(hua)柴(chai)(chai)油機尾(wei)(wei)氣(qi)的(de)(de)車(che)用(yong)品，是SCR方案的(de)(de)必需添(tian)加劑，一般(ban)由百分之32.5的(de)(de)高純尿素和(he)百分之67.5的(de)(de)去離(li)子水組成。車(che)用(yong)尿素的(de)(de)用(yong)途主要(yao)有(you)：1、在車(che)輛中(zhong)主要(yao)起(qi)到凈(jing)化(hua)(hua)(hua)尾(wei)(wei)氣(qi)的(de)(de)作用(yong)，能(neng)與尾(wei)(wei)氣(qi)中(zhong)的(de)(de)氮氧化(hua)(hua)(hua)物(wu)(wu)發(fa)(fa)生(sheng)反應(ying)，將尾(wei)(wei)氣(qi)中(zhong)的(de)(de)氮氧化(hua)(hua)(hua)合物(wu)(wu)（NOx）催化(hua)(hua)(hua)還原成無害(hai)的(de)(de)氮氣(qi)（N2）和(he)水（H?O）排(pai)出，減(jian)少氮氧化(hua)(hua)(hua)物(wu)(wu)排(pai)放(fang)，現(xian)在對重型卡客(ke)車(che)尾(wei)(wei)氣(qi)的(de)(de)檢測(ce)越來越多嚴格，不用(yong)車(che)用(yong)尿素就不達標。2、車(che)用(yong)尿素還有(you)一個用(yong)途，那就是能(neng)優(you)化(hua)(hua)(hua)發(fa)(fa)動機性(xing)能(neng)和(he)燃(ran)料消耗(hao)，減(jian)少柴(chai)(chai)油消耗(hao)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(che)(che)用(yong)尿(niao)素是(shi)指濃度為32.5%且(qie)溶劑(ji)(ji)為超純水的(de)尿(niao)素水溶液，生(sheng)產原(yuan)(yuan)料(liao)為車(che)(che)用(yong)尿(niao)素專用(yong)原(yuan)(yuan)料(liao)和超純水，它(ta)進入(ru)汽(qi)車(che)(che)內部后，通過(guo)尿(niao)素罐噴射(she)系統，噴射(she)于汽(qi)車(che)(che)排(pai)氣(qi)管發(fa)生(sheng)反應；排(pai)氣(qi)管上安(an)裝(zhuang)有尿(niao)素計量(liang)噴射(she)裝(zhuang)置(zhi)，在溫度達到300℃-500℃時自(zi)動噴入(ru)尿(niao)素溶液，在催化(hua)劑(ji)(ji)的(de)作用(yong)下尿(niao)素（NH2CONH2）水解產生(sheng)NH3和CO2，NH3與NOx反應，生(sheng)成(cheng)氮(dan)氣(qi)和水排(pai)出，起(qi)到凈(jing)化(hua)尾氣(qi)的(de)作用(yong)。
