Abstract:
An engine assembly includes an engine block defining a cylinder, an exhaust system, and an exhaust gas recirculation system. A first exhaust valve is configured to control fluid communication from the cylinder to the exhaust system. A second exhaust valve is configured to control fluid communication from the cylinder to the exhaust gas recirculation system. The second exhaust valve is selectively activatable and deactivatable independently of the first exhaust valve.
