valve-lash control

This paper discusses, according to power matching rule, the load pressure P_L and flow capacity Q_L of valve-control asymmetric actuating unit, which offers a reference to study on its kinematics and dynamic characteristics and optimum design.

根据功率匹配原则，讨论了阀控非对称动力机构（阀控单活塞杆液压缸）的负载压力pL和负载流量QL，以供对其静动态特性研究及优化设计作参考。

The test result showed that it could decrease the rotational speed between the drive part and the driven part when clutch was locked, and improve the shift quality of AMT with control of the fuel stop valve.

试验结果表明，换挡过程中通过控制断油电磁阀，可以减小离合器接合时主、被动部分的转速差，显著改善了AMT的换挡品质。

This paper presents two multipoint detection systems of air cleanliness, which are used in the environment inspection: the solenoid valve control system and the RS-485 bus system. It describes how each works and compares the advantages and disadvantages of these two methods.
