As shown in Figure 9 b,d, a hydraulic snubber does not contribute to soft valve landing. On the other hand, Figure 10 shows that the modified actuator model, i.e., EH-CEVA II, meets the performance requirement as expected. The landing velocity of a valve actuator is less than 0.25 m/s which is a target value of valve landing velocity.
