Abstract
At present, the electro-hydraulic variable valve is the development trend of variable valve technology. However, most electro-hydraulic variable valves require high-responsiveness solenoid valves, which are costly and complex to control. Besides, VVT and VVL technologies, which are mature and widely used in the market, are limited and hierarchical in regulating valve parameters. To solve the problems, a cam-driven variable hydraulic valve mechanism was developed and the bench test was carried out. The results show that, the designed mechanism can achieve full continuous variable of open angle, close angle and valve lift. And the cost of the system is lower and its control operation is convenient.
