n.吹去(漏氣；不密封)

Blowby is basically the leakage of compressed air-fuel mixture and burned gases past the piston rings into the crankase. 竄氣，基本上是被壓縮的空燃混合氣和燃燒后的氣體的泄漏，它通過活塞環(huán)進(jìn)入曲軸箱。

Piston rings require an oil film between ring and liner and between ring and piston groove to seal against these high pressures and to prevent blowby. 為了密封，在活塞環(huán)與連桿之間、活塞環(huán)與或活塞槽之間需要一層油膜以承受住這些高壓、阻止漏氣。

The additives in the oil counteract this action by minimizing breakdown, neutralizing blowby products, and helping to form a protective film. 機(jī)油中的添加劑使軸承損耗量最小化，使漏氣中性化，這有助于形成一層保護(hù)層。
