[0035]The organization of the inlet and outlet airflow of the improved mixed-flow turbocharger nozzle ring is optimized through the design of the flow channel of the turbine casing and the application of three-dimensional blades, aiming at the air leakage loss and complex structure caused by the external crank-link mechanism , and the problems of low transmission efficiency of the built-in space four-bar mechanism are solved by designing a built-in nozzle ring actuator in the present invention. The blades of the nozzle ring are also changed from the original symmetrical or aerodynamic blades to adjustable anti-spherical concentric arc-shaped two-dimensional or three-dimensional curved blades. The specific implementation of the mixed-flow turbocharger nozzle ring involved in the present invention is set forth below in conjunction with the accompanying drawings: when the operating conditions of the engine change, the pneumatic actuator or electric actuator acts on the rocker asse...
