一种汽车尾气清洁剂制备方法，包括以下步骤：
S1、按照权利要求1~2任意一项所述的汽车尾气清洁剂的配方称取各个组分备用，将十六烷基脂肪醇、十八烷基脂肪醇以及二十二烷基聚氧乙烯醚甲基丙烯酸酯溶于多元粗醇和异丙醇的混合溶液中，之后依次加入十二烷基硫酸乙醇胺盐、聚丙烯酰胺、烷基糖苷和端羟基聚环氧氯丙烷醚，搅拌后均匀后静置；
S2、将丙二醇甲醚醋酸酯、硝酸异丙酯、十二烷基醇酰胺混合均匀后依次加入N，N-双羟乙基烷基酰胺、十二烷基甲基二氯硅烷、椰油酸二乙醇酰胺，搅拌均匀后，降至常温，静置；
S3、将乙二醇二缩水甘油醚放置锥形漏斗中静置24小时，将下层液排出，取出上层溶液，备用；
S4、将S1和S2得到的溶液进行混合后加入S3中的上层溶液，搅拌后依次加入十二烷基甲基二甲氧基硅烷、三乙醇胺、乙二胺四乙酸、聚乙烯吡咯烷酮搅拌均匀后得到产品。
作为进一步的技术方案，所述S1中加入十二烷基硫酸乙醇胺盐和聚丙烯酰胺之前升温至70℃并且搅拌30min，加入后搅拌10min后开始自然降温，降温至40℃时加入基糖苷和端羟基聚环氧氯丙烷醚，搅拌并且维持20min后降至常温，静置。
作为进一步的技术方案，所述S2中升温至40℃后再缓慢加入椰油酸二乙醇酰胺，搅拌5min后，降至常温。
作为进一步的技术方案，所述S4中依次加入十二烷基甲基二甲氧基硅烷、三乙醇胺、乙二胺四乙酸、聚乙烯吡咯烷酮后，升温至80℃，搅拌并维持2h，再降温至50℃再搅拌并维持30min，降至室温。
与现有技术相比，本发明工作原理和有益效果为：
1、本发明中，研发出了一种新型的尾气清洁剂的配方，该配方制备的清洁剂与汽油的相容性极好，实验数据表明在高温和低温状态下本发明制备的产品都与汽油有较好的混和效果。
2、本发明中，利用独特的配方后再利用特殊的工艺进行制备，其中制备方法中采用了逐级混合的方法，配合温度以及时间的变化，得到的清洁剂的产品在排放物试验上可以看出，具备了极佳的清洁效果，并且还大大提高了汽车的动力性能以及节油效果。
3、本发明中，将乙二醇二缩水甘油醚放置锥形漏斗中常温静置24小时，将下层液排出，取出上层溶液，进行进一步复配，实施例中采用这一步骤时，如果静置24小时后没有出现分层的现象而是整体凝结为胶体状，则更换乙二醇二缩水甘油醚，如果静置24小时后没有出现分层，也没有凝固，则直接使用该乙二醇二缩水甘油醚即可，实验数据中表明，实施这一步骤后能够提高清洁剂的质量，使其加入到汽油中后大大提高了尾气净化效果以及提高了汽车的性能。
