n.吹去(漏气；不密封)
Blowby is basically the leakage of compressed air-fuel mixture and burned gases past the piston rings into the crankase. 窜气，基本上是被压缩的空燃混合气和燃烧后的气体的泄漏，它通过活塞环进入曲轴箱。
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. 为了密封，在活塞环与连杆之间、活塞环与或活塞槽之间需要一层油膜以承受住这些高压、阻止漏气。
The additives in the oil counteract this action by minimizing breakdown, neutralizing blowby products, and helping to form a protective film. 机油中的添加剂使轴承损耗量最小化，使漏气中性化，这有助于形成一层保护层。
