vapor lock

名詞

可算名詞 不可算名詞 特に

(mechanical engineering) A problem mostly affecting gasoline-fueled internal combustion engines, where the liquid fuel changes state from liquid to gas while still in the fuel delivery system, reducing the pump pressure and causing transient power loss or complete stalling.

日本語の意味

内燃機関、特にガソリンエンジンにおいて、燃料が燃料供給システム内で液体から気体に変化する現象。これにより燃料ポンプの圧力が低下し、一時的な出力低下やエンジンの停止を引き起こす問題。

意味（2）

(especially mechanical engineering) Synonym of air lock.

The Coast Guard Marine Safety Center modeled and analyzed the lube oil levels in the main engine sump in a static condition. The safety center concluded that with 1,226 gallons of oil in the sump, as was likely on the accident voyage, and a 5-foot trim by the stern (0.4°), the bellmouth opening of the line leading from the sump to the lube oil pumps would break the oil's surface at an 18° port list. At that point, the bellmouth would no longer be submerged in the lube oil and air would enter the pumps, causing a vapor lock.
