高温自润滑配气阀座是某工程发动机的关键部件。
The high temperature self-lubricating valve actuating mechanism is the key part of an engineering engine.
建立进排气阀模型以确定配气相位； 建立气缸内湍流燃烧、传热、气体流动模型；
The models of combustion, heat transfer and air-flow were established and the model of mechanical efficiency was established as there are frictions between engine parts.
该空压机在运行时活塞始终在旋转，且运行一周，自动完成进、排气两个压力循环，无须进、排气阀门等配气机构。
When it works, the piston rotates all the time, and runs a circle to automatically complete two pressure circulations of charging and exhausting without air distributing mechanism.
