The tetraethyl lead increased the ignition temperature of the gasoline eliminating pre-ignition.

而四乙基铅能够提高汽油的燃点，解决提前燃烧的问题。

On the other hand, lead was easy to extract and work, and almost embarrassingly profitable to produce industrially, and tetraethyl lead did indubitably stop engines from knocking.

另一方面，铅很容易提炼和开采，大规模生产极其有利可图，四乙铅确实可以防止发动机爆震。

In addition to its use as a wine sweetener and a paint improver, lead offered even more benefits as a gasoline additive in the form of a compound known as tetraethyl lead.

铅除了能当酒类增甜剂和油漆添加剂之外，铅的一种化合物作为汽油添加剂还能提供更多的好处，也就是四乙基铅。

In 1921, while working for the General Motors Research Corporation in Dayton, Ohio, he investigated a compound called tetraethyl lead (also known, confusingly, as lead tetraethyl), and discovered that it significantly reduced the juddering condition known as engine knock.

1921年，他在位于俄亥俄州代顿的通用汽车研究公司工作期间，对一种名叫四乙铅的化合物作了研究，发现它能大大减少震动现象，即所谓的发动机爆震。
