为了有效地抑制汽油发动机的爆震现象,传统的有效方法是在汽油中添加四乙基铅(TEL)和四甲基铅(TML)等防爆剂。但由于汽油燃烧之后,铅随废气排入大气,加剧了对环境的污染,因此许多工业发达国家及地区都先后立法禁止或限制含铅汽油的使用。许多汽车也都按使用无铅汽油进行设计,如美国通用汽车公司的凯迪莱克轿车就规定使用91~#无铅汽油。 但是,由于目前各地无铅汽油站甚少。加油的困难,使一些用户急欲改为使用含铅汽油。有的用户甚至误以为只要把无铅汽油汽车的细小加油孔改大。便于含铅汽油大油枪的加油就行。 为此,提醒用户千万慎重对待。否则用不了多久,这些昂贵的高级轿车技术性能就会急剧
In order to effectively suppress the detonation of gasoline engines, a traditional effective method is to add anti-knocking agents such as tetraethyl lead (TEL) and tetramethyl lead (TML) to gasoline. However, after the combustion of gasoline, lead is discharged into the atmosphere with the exhaust gas, exacerbating the environmental pollution. Therefore, many industrialized countries and regions have successively enacted laws to prohibit or restrict the use of leaded gasoline. Many cars are also designed using unleaded petrol, such as the United States General Motors Cadillac sedan on the provisions of the use of 91 ~ # unleaded petrol. However, due to the current unleaded petrol stations around the very few. Refueling difficulties, so that some users are anxious to switch to the use of leaded gasoline. Some users even mistakenly believe that as long as the small fuel-free petrol car larger openings. Leaded gasoline guns for refueling on the line. To this end, remind users to be careful. Otherwise, it will not take long before these expensive limousines will perform dramatically
