It wasn't easy, other additives had to be developed for cars that had been designed to run on leaded gasoline, many of which had their own problems.

这并不容易，汽油公司要开发出新的添加剂，以用于原本设计成使用含铅汽油的汽车，更别提很多无铅添加剂还有自身的问题。

No. What else happened? DDT was banned, the  catalytic converter was introduced, leaded gas was removed from the environment. All of this happened  in those five years, while we were still at war.

不，还有什么事发生？ DDT 被禁止， 催化转化器被引入，含铅气体被从环境中移除。 所有这一切都发生在这五年里， 当时我们还在打仗。
