Abstract: An assembly for controlling a flow of exhaust gas from an engine includes a blowdown manifold and a scavenge manifold adapted to be coupled to the engine for receiving the exhaust gas. The assembly also includes a valve system including a blowdown pipe coupled to the blowdown manifold, a scavenge pipe coupled to the scavenge manifold, a scavenge valve member coupled to the scavenge pipe and disposed within the scavenge passage, and at least one actuator operably coupled to the scavenge valve member. The assembly further includes a turbocharger coupled to the blowdown pipe, with the turbocharger including a turbine housing defining a turbine housing interior. The scavenge valve member of the valve system is disposed outside of the turbine housing interior.
