Exhaust Stroke

定义 Definition

exhaust stroke(发动机术语):在往复式内燃机(常见为四冲程发动机)中,活塞向上运动并使排气门开启,将燃烧后的废气从气缸排出到排气系统的那个“冲程/行程”。(在四冲程:进气、压缩、做功、排气之中对应“排气冲程”。)

发音 Pronunciation

/zst strok/

例句 Examples

During the exhaust stroke, the exhaust valve opens to let the burned gases out.
在排气冲程中,排气门打开,让燃烧后的废气排出。

If the exhaust stroke is restricted by a clogged muffler, the engine may lose power and run hotter.
如果排气冲程因消声器堵塞而受阻,发动机可能会动力下降并且温度更高。

词源 Etymology

exhaust 源自拉丁语 exhaurīre(“抽空、耗尽”),引申为“排出(气体)/耗尽”。stroke 原意是“一次击打/一次动作”,在机械语境中发展为“一次往复运动的行程/冲程”。合起来 exhaust stroke 就是“用于排出废气的那一次行程”。
