一种汽油复合高效节能清净增效剂及其制备方法
技术领域
本发明涉及石油化工技术领域，尤其涉及一种汽油复合高效节能清净增效剂。
背景技术
汽油燃烧产生有毒有害物质的原因不仅因所含硫磷等杂质外，还由于汽油的不完全燃烧，从而导致一氧化碳及碳氢化合物等有害气体的形成。此外，由于采用空气助燃，在燃烧室的高温、高压条件下还会生成氮氧化物，以上物质进入空气中，将会污染环境，并对人体健康产生不利影响。目前，市场上汽油清净剂品牌较多，但大多数均存在不同类别的缺陷：不能有效清除掉喷油嘴、进气门、火花塞、缸内积碳等多部位的积碳，使得发动机内部的磨损仍然很大，导致发动机的使用效率较低，因而依然存在油耗升高，尾气超标等问题。
