发明名称 Method and device for controlling an electrohydraulic unit for actuating the valves of an endothermic engine
摘要 A method for controlling an electrohydraulic unit for actuating the valves of an endothermic engine, in which the electrohydraulic unit is provided with a hydraulic actuator for opening the respective valve with a pressurized liquid, and a spring that is antagonistic to the hydraulic actuator in order to close the valve, provides for the control of the connection time between the hydraulic actuator and a first branch containing the pressurized liquid as a function of a predetermined time characteristic of the electrohydraulic unit.
