A wastegate assembly in a turbine of an internal combustion engine is provided. The wastegate assembly includes a wastegate conduit bypassing a turbine rotor, a valve sealing plate configured to seat and seal on a wastegate conduit outlet in a closed position, and a flow diverting tab coupled to the valve sealing plate, extending upstream of the wastegate conduit outlet, and separating a wastegate conduit outflow and a turbine rotor outflow.

Wastegate assembly in a turbine

Systems and methods for improving seal performance in a centrifugal water pump for an internal combustion engine increase static pressure at the seal by incorporating a combination of slots and ribs into a seal cavity of the pump housing that are positioned to convert dynamic fluid pressure into static pressure at the seal while reducing coolant velocity at the seal. Vent holes in the impeller having an appropriate size and location may also be used to increase the static pressure at the seal to enhance seal performance.
