ABSTRACT:
A method and apparatus of carrying out exhaust gas recirculation and compression release retarding is disclosed for use during both positive power and retarding operation of an overhead cam internal combustion engine. Energy is derived from an engine component and stored as potential energy. The stored energy is selectively applied to a valve actuator to carry out exhaust gas recirculation in an engine cylinder. The energy derived from the engine may be stored in the form of a compressed hydraulic fluid and selectively applied to the valve actuator with an electronically controlled trigger valve. The valve actuator may be a slave piston having an inner core and an outer sleeve capable of opening the valve of the cylinder in response to independent exhaust gas recirculation and compression release hydraulic systems.
