TURBINE HOUSING AND MANIFOLD ASSEMBLY WITH CONTROL VALVE

A turbine assembly can include a manifold that includes separate conduits for receipt of exhaust from a first number of cylinders and a second number of cylinders, turbine inlet passages and a valve seat disposed between the separate conduits and the turbine inlet passages; and a valve set in the valve seat that includes a rotational axis and an outer surface that includes separate recesses, where rotation of the valve controls exhaust flow from the separate conduits to the turbine inlet passages.
