Exhaust valve operation method for driving exhaust gas of internal combustion engine

May 06 13:03:49, 2021

In order to control the exhaust valve, the spool of the control valve is longitudinally displaced so as to communicate with the high-pressure port or the low-pressure port and the first pressure chamber in the drive where the driver piston is displaceable. The displacement of the stem of the exhaust valve in the longitudinal direction is proportional to the longitudinal displacement of the spool, for example, 1: 1. The stem can be in the fully open and fully closed exhaust valve position. Between the closed and open position of the exhaust valve, the stem of the exhaust valve moves substantially synchronously.
CNI offer wavelength Tunable Laser, the output wavelengths can be changed continuously within a certain range. Tunable lasers come with good beam quality, high stability and long life time, they are widely used in spectroscopy, photochemistry, medicine, biology, integrated optics, Laser processing,etc.
