Abstract

A method and apparatus for carrying out a variable timing exhaust gas recirculation is disclosed for use during both positive power and retarding operation of an internal combustion engine. Motion or energy is derived from an engine component and stored as potential energy. The stored energy (400) is selectively applied to a valve actuator (300) to carry out exhaust gas recirculation in an engine cylinder (40). The energy derived from engine may be stored and selectively applied to the valve actuator (300) with an electronically controlled trigger valve (400). The valve actuator (300) may be a slave piston (300) having an inner core (360) and an outer sleeve (370) capable of opening the exhaust valve (30) of the cylinder (40) in response to independent exhaust gas recirculation and compression release hydraulic systems.
