description This paper describes a modeling method for electro-hydraulic variable valve mechanism based on CATIA. It focuses on the principle of the mechanism and the models of some parts with oil circuits in the hydraulic system and the moving principle of the actuation system. The additional damping cavity is used for pressure compensation. The actual mechanism based on the model precisely provides the hydraulic force to drive the valve to move quickly and smoothly at the right time. The modeling is of great importance for the valve movement on variable valve timing. Electro-hydraulic variable valve mechanism has been used in ZS1105 gasoline engine, and has achieved CAI combustion on some EGR strategies. Experiment studies verify that the mechanism based on the model is credible.
