汽车尾气英语怎么说

英文中，汽车尾气通常被称为 "exhaust" 或 "tailpipe emissions"。这些术语来源于汽车的排气系统，即汽车的排气管，它从汽车的尾部喷出废气。例句如下：

The new regulations will require car manufacturers to reduce tailpipe emissions by 20% over the next five years.

Electric cars produce zero tailpipe emissions, making them a more environmentally friendly option.

The high levels of exhaust and tailpipe emissions from cars and trucks are a major contributor to air pollution in cities.
