Description

一种燃油动力提升剂及其制备方法
技术领域
本发明属于燃油添加剂技术领域，具体涉及一种燃油动力提升剂及其制备方法。
背景技术
汽油爆震是一种燃烧现象，有很多名称，比如“燃料爆震”、“火花爆震”、“积炭爆震”或“砰震”。在出现爆震的情况下，因为压力突然增加，会导致讨厌的噪音和功率损失。另外，爆震还会导致过热，缩短阀门、火花塞以及活塞等发动机部件的使用寿命。
在用新式无铅汽油代替有铅汽油以后，通常会减少辛烷值以节约精炼成本。要防止低辛烷值的无铅汽油出现爆震，则必须降低高压缩发动机的性能，这样会损失功率以及燃料的经济性。无铅汽油所产生的燃烧室沉积物会导致辛烷值要求提高(ORI)。针对常规无铅汽所设计的发动机可能会在使用15,000到20,000英里(24,000到32,000公里)后开始爆震。用户经常不得不转而采用更贵的高价无铅汽油，以防止因为辛烷值要求提高而导致爆震。
一些当代发动机配备了爆震传感器，可以检测因为辛烷值要求提高而增加的爆震。在爆震传感器检测到初期爆震之后，会自动降低发动机的性能，以防止爆震并因此损坏发动机。这样，就会减少输出功率，并提高燃料消耗。高辛烷值汽油可以恢复因为辛烷值要求提高而损失的功率和燃料经济性。
带有催化转化器的当代汽车可以减少排气管的排气量并改善环境。如果尾气中有铅或磷，则会使催化剂中毒。使用无铅汽油，可以解决铅污染催化剂的问题。不过，在尾气中含有少量来自曲轴箱润滑油中的磷。在经过一段时间后，这些磷会堆积在催化剂上，并降低催化剂的转化效率。
经过多年的发展，喷油***代替了汽化燃油***。可是喷油嘴容易不充分的燃烧物被弄脏。这些脏物和沉积物会对燃油的喷雾模式产生不利影响，从而增加油耗和排气量。目前发现进气阀沉积物也会对废气的排放量产生不利影响。因此需要采用具有足够防爆震性能(辛烷值)的燃料来防止爆震。并且现在的性能提升剂在油路积碳的去除以及节油率等综合性能总是难以令人满意。
