废气

Optimised fuel consumption and emission levels are further achieved by the new 175/70 tyres, which provide less surface friction, and the 14 wheels with closed hubcaps, which generate less air resistance than open alloy wheels.

优化燃料消耗和废气排放水平，进一步实现新的七十零分之一百七十五轮胎，提供较少的表面摩擦力，以及14的封闭轮毂，它产生了非公开的合金轮毂空气阻力轮。

The sources of pollution are as follows, 1,feces discharged from public washroom emit an unbearable naucious odor; 2、water discharged from factories is black and odorous, covered with floating waste 3、air emission from factories smells pungent and spreads to every corner,4、air emission from fertilizer factories contains dust,lead, and coal ash, and other particles harmful to health 5、grasslands and lawns in parks are covered with litters which are unhygenic and unsightly.

造成环境污染的污染源是：1、公共厕所排出的粪便散发出难闻的气味，让人恶心。2、工厂排出的废水又黑又臭，还浮着一些秽物。3、工厂排出的废气很刺鼻，会散发到小镇的各个角落。4、化肥厂排出的气体中含有粉尘、铅、煤灰等对人体有害的物质。5、公园的草坪上常有游人丢弃的垃圾，既不卫生，又影响市容。

A projector with a high-wattage lamp gets much hotter than one with a low-wattage lamp, requiring a more powerful air circulation system and resulting in louder, hotter exhaust.

一个有高瓦数灯泡投影得到一个低功率的灯比一个更热，需要更强大的空气循环系统和呼声，更热的废气造成。

Some massifs were piled up by the discarded porcelain slices over many years .Can you imagine that how many years could the massifs be shaped by the kiln factory on a large production of scale in the remote Tang Dynasty ?

有些小山丘就是当年窑场废气物累年堆积而成，真不知在那遥远的唐代，长沙窑是怎样的生产规模，又是延续了多少年，才能遗留下这么大量的残存物。

An actuator can adjust the angle of these vanes, in turn vary the angle of exhaust flow.

一个驱动器可以改变这些叶片的角度，进而改变了废气流的角度。

Also as you can see, to match the turbos they've fabricated a custom stainless manifold, custom stainless dump pipes and fitted up a pair of external wastegates.

此外， 读者们也可以清楚的看到其中手工自制的白铁头段以及一对 wastegate 还有给 wastegate 的白铁废气排放管路。
