Abstract
A turbocharger assembly for an internal combustion engine includes a bypass valve for controlling a flow of exhaust gas from a second group of exhaust ports of a cylinder head assembly. When disposed in an open position, the bypass valve allows exhaust gas from the second group of exhaust ports to combine with exhaust gas from a first group of exhaust ports to spin a turbine of the turbocharger assembly. When disposed in a closed position, the bypass valve forces the exhaust gas from the second group of exhaust ports through an Exhaust Gas Recirculation (EGR) passage to an intake manifold to establish a dedicated EGR system.
