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

而四乙基铅汽油的燃点，解决前燃烧的问题。

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，铅很容易炼和开采，大规模生产极其有利可图，四乙铅确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更多的好处，也就是四乙基铅。
