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(niao)素(su)是指濃度為(wei)32.5%且溶劑(ji)為(wei)超純(chun)水(shui)(shui)的(de)(de)尿(niao)素(su)水(shui)(shui)溶液,生產原(yuan)料為(wei)車用(yong)尿(niao)素(su)專(zhuan)用(yong)原(yuan)料和(he)(he)超純(chun)水(shui)(shui),它進(jin)入(ru)(ru)汽車內(nei)部后,通過尿(niao)素(su)罐噴射(she)系(xi)統,噴射(she)于汽車排氣(qi)(qi)管(guan)發生反應;排氣(qi)(qi)管(guan)上安(an)裝有尿(niao)素(su)計量噴射(she)裝置,在溫度達到(dao)300℃-500℃時自動噴入(ru)(ru)尿(niao)素(su)溶液,在催化劑(ji)的(de)(de)作(zuo)(zuo)用(yong)下尿(niao)素(su)(NH2CONH2)水(shui)(shui)解(jie)產生NH3和(he)(he)CO2,NH3與NOx反應,生成氮氣(qi)(qi)和(he)(he)水(shui)(shui)排出,起(qi)到(dao)凈化尾氣(qi)(qi)的(de)(de)作(zuo)(zuo)用(yong)。
