Abstract

Exhaust gas re-circulation is achieved internally in an internal combustion engine having intake and exhaust valves actuated by a camshaft. A controller monitors at least one engine parameter and automatically actuates an electrically actuated fluid operated brake actuator at a predetermined timing of movement of an engine piston to cause the actuator to maintain the exhaust valve at an intermediate position between a full open position and a closed position of the exhaust valve and cause exhaust gasses to be delivered from the exhaust manifold to the combustion chamber of the engine.
