Abstract
An exhaust aftertreatment system for an internal combustion engine includes an exhaust manifold that is configured for fluid communication with an exhaust port to receive an exhaust gas flow. It also includes a primary turbocharger having a turbine inlet configured for fluid communication with the exhaust manifold to receive the exhaust gas flow and pass it to an outlet. It also includes an exhaust bypass valve that is operable for movement between an open position and a closed position, the exhaust bypass valve having an inlet that is configured for fluid communication with the exhaust manifold in the open position to receive the exhaust gas flow and pass it to an outlet. Still further, it includes an exhaust aftertreatment device configured for thermal communication with the exhaust manifold, the device having an inlet configured for fluid communication with the turbine and bypass outlets to receive the exhaust gas flows therefrom.
