Abstract:
An engine is provided that includes an exhaust gas recirculation (EGR) conduit in fluidic communication with a first exhaust valve in a cylinder and an intake system, an exhaust conduit in fluidic communication with a second exhaust valve in the cylinder and an emission control device. During operation with the first valve active and the second valve deactivated, a fixed EGR level can be provided. However, during operation with the first valve deactivated and the second valve active, increased engine output can be achieved with reduced EGR without requiring additional exhaust throttling or switching valves.
