发动机顶气门空气回收

英文回答：

Engine Top Vent Air Recovery.

Engine top vent air recovery is a process that captures

and reuses the air that is released from the top of an

engine. This air is typically released into the atmosphere,

but it can be captured and reused to improve engine

efficiency and reduce emissions.

There are two main types of engine top vent air

recovery systems:

Positive crankcase ventilation (PCV) systems use a

vacuum to draw air from the top of the engine and route it

back into the intake manifold. This helps to reduce

emissions by preventing unburned hydrocarbons from escaping

into the atmosphere.

Air-oil separator (AOS) systems use a filter to remove

oil from the air that is released from the top of the

engine. This helps to prevent oil from entering the intake

manifold and causing engine damage.

Engine top vent air recovery systems can provide a

number of benefits, including:

Reduced emissions.

Improved engine efficiency.

Extended engine life.

Engine top vent air recovery systems are a relatively

simple and inexpensive way to improve the performance of an

engine. They are becoming increasingly common on new

vehicles, and they are likely to become even more common in

the future as emissions regulations become more stringent.

发动机顶气门空气回收。

发动机顶气门空气回收是指捕获和再利用从发动机顶部释放的

空气。这种空气通常会释放到大气中，但可以捕获和再利用以提高

发动机效率并减少排放。

有两种主要的发动机顶气门空气回收系统：

曲轴箱强制通风 (PCV) 系统使用真空从发动机顶部抽取空气

并将其送回进气歧管。这有助于减少排放，因为它可以防止未燃烧

的碳氢化合物逃逸到大气中。

空气-机油分离器 (AOS) 系统使用过滤器从发动机顶部释放的

空气中去除机油。这有助于防止机油进入进气歧管并导致发动机损

坏。

发动机顶气门空气回收系统可以提供许多好处，包括：

减少排放。

提高发动机效率。

延长发动机寿命。

发动机顶气门空气回收系统是一种相对简单且经济的方式来提

高发动机的性能。它们在新车中变得越来越普遍，并且随着排放法

规变得更加严格，它们在未来可能会变得更加普遍。
