Valve System And Assembly Including The Same

A valve system for controlling a flow of exhaust gas from an engine of a vehicle, with the vehicle including an assembly including a turbocharger, with the turbocharger including a turbine housing defining a turbine housing interior, said valve system comprising:

• a blowdown pipe adapted to be coupled to a blowdown manifold, with said blowdown pipe defining a blowdown passage adapted to receive the exhaust gas from the blowdown manifold and the engine;
• a scavenge pipe adapted to be coupled to a scavenge manifold, with said scavenge pipe defining a scavenge passage adapted to receive the exhaust gas from the scavenge manifold and the engine independent from said blowdown passage;
• a scavenge valve member coupled to said scavenge pipe and disposed within said scavenge passage, with said scavenge valve member being moveable to regulate the flow of exhaust gas through said scavenge passage;
• and
• at least one actuator operably coupled to said scavenge valve member, with said at least one actuator being adapted to selectively control movement of said scavenge valve member to regulate the flow of exhaust gas;
• wherein said first valve member is adapted to be disposed outside of the turbine housing interior.

A vehicle comprising:

• an engine;
• and
• an assembly for controlling exhaust gas from said engine, said assembly comprising,
• a blowdown manifold coupled to the engine for receiving the exhaust gas from said engine;
• a scavenge manifold coupled to the engine for receiving the exhaust gas from said engine independent from said blowdown manifold;
• a valve system comprising,
• a blowdown pipe coupled to said blowdown manifold, with said blowdown pipe defining a blowdown passage to receive the exhaust gas from said blowdown manifold,
• a scavenge pipe coupled to said scavenge manifold, with said scavenge pipe defining a scavenge passage to receive the exhaust gas from said scavenge manifold,
• a scavenge valve member coupled to said scavenge pipe and disposed within said scavenge passage, with said scavenge valve member being moveable to regulate the flow of exhaust gas through said scavenge passage, and
• at least one actuator operably coupled to said scavenge valve member, with said at least one actuator being adapted to selectively control movement of said scavenge valve member to regulate the flow of exhaust gas;
• and
• a turbocharger coupled to said blowdown pipe, with said turbocharger comprising a turbine housing defining a turbine housing interior, and a turbine wheel disposed within the turbine housing interior;
• wherein said scavenge valve member is disposed outside of said turbine housing interior.
