Abstract

Lost motion systems and methods for providing engine valves with variable valve actuation for engine valve events are disclosed. The system may include a master piston (210) hydraulically linked to a slave piston (230), and a dedicated cam (110) operatively connected to the master piston. The slave piston may be disposed substantially perpendicular to the master piston in a common housing. The slave piston is adapted to actuate one or more engine valves (300). The slave piston may incorporated an optical valve seating assembly into its upper end. A trigger valve (260) may be operatively connected to the master-slave hydraulic circuit to selectively release and add hydraulic fluid to the circuit.
