Beschreibung
Zusammenfassung:	The utility model discloses a closed breathing system for preventing exhalation oil, which comprises an engine, a cylinder head arranged on the engine, an integrated breathing system cylinder head cover arranged on the cylinder head and an engine air inlet system arranged on the cylinder head, an air inlet pipeline arranged on the engine air inlet system, and an air inlet air filter arranged at the tail end of the air inlet pipeline. A breathing system closed pipeline is arranged between the air inlet pipeline and the integrated breathing system cylinder head cover, and a pressure one-way valve and a pressure abnormity alarm device are arranged on the breathing system closed pipeline. The pressure one-way valve and the pressure abnormity alarm device are arranged on the closed pipeline of the breathing system, so that the phenomenon of engine oil exhalation caused by overlarge negative pressure of the pipeline of the closed breathing system can be effectively avoided. 本实用新型公开了一种预防呼机油闭式呼吸系统，包括发动机，发动机上设有气缸盖，气缸盖
