Turbine assembly with controlled exhaust flow valve
The patent US12071888B2 describes a turbine assembly designed to manage exhaust flow from multiple cylinders in an internal combustion engine. The assembly features a manifold with separate conduits for exhaust from two distinct groups of cylinders, along with turbine inlet passages separated by a wall. A key component is a valve set within a valve seat, which includes a rotational axis and an outer surface with three recesses arranged in pie-shaped sections. This valve can be rotated to either allow unrestricted exhaust flow from the conduits to the turbine inlet passages or to restrict this flow, depending on its alignment with the wall. The design also accommodates various configurations, such as feeding a single turbine housing scroll or multiple scrolls, and includes provisions for exhaust gas recirculation.
Additionally, the patent outlines methods for operating the turbine assembly, emphasizing the valve's ability to transition between different flow states. The valve can be positioned to enhance engine braking by increasing exhaust backpressure or to facilitate exhaust gas recirculation back to the engine intake. The assembly is designed with practical features, including exhaust flanges for manifold inlet passages and an opening for valve insertion, ensuring compatibility with engine components. The valve's operation is further enhanced by a control arm that allows for precise adjustments, making the turbine assembly versatile for various engine performance needs.
