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)用尿素(su)是(shi)指濃度為32.5%且溶(rong)劑(ji)為超純(chun)水(shui)(shui)(shui)的(de)尿素(su)水(shui)(shui)(shui)溶(rong)液，生產(chan)原料為車(che)用尿素(su)專用原料和超純(chun)水(shui)(shui)(shui)，它進入(ru)汽車(che)內部后，通過(guo)尿素(su)罐噴射(she)系統，噴射(she)于汽車(che)排(pai)氣管發生反(fan)應(ying)(ying)；排(pai)氣管上安(an)裝(zhuang)有(you)尿素(su)計(ji)量(liang)噴射(she)裝(zhuang)置，在溫度達到300℃-500℃時自動(dong)噴入(ru)尿素(su)溶(rong)液，在催化劑(ji)的(de)作(zuo)用下尿素(su)（NH2CONH2）水(shui)(shui)(shui)解產(chan)生NH3和CO2，NH3與NOx反(fan)應(ying)(ying)，生成(cheng)氮氣和水(shui)(shui)(shui)排(pai)出，起(qi)到凈化尾氣的(de)作(zuo)用。
