[海洋巡護科輪機組] 輪機工程(包括推進裝置、輔機與輪機英文)
第 四 題
請將下列輪機英文翻譯成中文:(25分)
Theoretically, the two-stroke cycle engine, with one working or power stroke every revolution, develops twice the power of a four-stroke engine of the same swept volume. The four-stroke engine rotating at medium speed, usually between 250 and 750 rev/min, is used for auxiliaries such as generators and sometimes for main propulsion with a gearbox.

看到這題翻譯應先拆解兩個長句的文法結構,並快速辨識出核心的輪機專業術語。第一句的重點在於正確翻譯「swept volume(掃掠容積)」並釐清行程與動力的因果關係;第二句則測驗對船舶設備如輔機(auxiliaries)及主推進(main propulsion)的理解,翻譯時需兼顧專業專有名詞的精準度與中文語氣的通順。

【譯文】 理論上,二行程引擎(Two-stroke Cycle Engine)每一轉均具備一個工作或動力行程(Working or Power Stroke),在相同掃掠容積(Swept Volume)的情況下,其所產生的動力為四行程引擎(Four-stroke Engine)的兩倍。 以中等轉速(通常介於每分鐘 250 至 750 轉之間)運轉的四行程引擎,主要應用於發電機(Generators)等輔機(Auxiliaries),有時亦會搭配齒輪箱(Gearbox)作為主推進裝置(Main Propulsion)。

二四行程引擎特性比較
💡 理解二、四行程引擎動力循環差異及船舶輔機與主推進之專業術語。
| 比較維度 | 二行程引擎 (Two-stroke) | VS | 四行程引擎 (Four-stroke) |
|---|---|---|---|
| 動力產生頻率 | 曲軸每一轉一次動力 | — | 曲軸每兩轉一次動力 |
| 理論動力輸出 | 同掃略容積下為二倍 | — | 同掃略容積下為一半 |
| 船舶常見用途 | 大型低速主機 | — | 中速輔機或主推進器 |
💬二行程著重高功率輸出,四行程則廣泛應用於中速輔助及推進設備。
