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 the flow of fluid from the cylinder to the exhaust system. A second exhaust valve configured to control the flow of fluid from the cylinder to the exhaust gas recirculation system. The second valve is deactivatable independently of the first valve, thereby enabling EGR flow.
