摘要
A system for accomplishing solenoid control of engine valves places a soldnoid valve between an oil gallery and the lost-motion actuator for each valve. Although the basic phasing for the valves is established by a camshaft, the actual phasing is accomplished by causing the valve actuators to execute lost-motion. The amount of lost-motion establishes the actual opening and closing phase angles for the valves. The amount of lost-motion of each actuator is established by the timing of the opening and closing of the corresponding solenoid valve. Oil that is pumped from the actuators can be stored in an accumulator that is connected to the gallery for subsequent use in replenishing the actuators.
