  • Patent number: 10669927
    Abstract: A rotor rotatably mounted within a turbocharger housing includes a turbine wheel and a shaft. The shaft connects the turbine wheel. The hub defines a turbine-wheel back-disk surface facing the portion of the housing containing the bearings, and the hub defines a blade-side surface. The turbine hub and the housing define a turbine-wheel back-disk cavity. The turbine hub forms a ring-shaped primary axial protrusion extending circularly around the turbine-wheel back-disk surface into a circular channel in the housing. The circular channel leads into a bypass that bypasses the turbine blades. A relief flow valve is placed in the bypass. The relief control valve is controlled to open when the bypass pressure is above a cutoff pressure, and close when it is below the cutoff pressure.

  • Patent number: 10422275
    Abstract: A wastegate valve device for a turbocharger includes a valve body, a swing arm configured to support the valve body, a rotating shaft to which the swing arm is fixed, a drive arm fixed to the rotating shaft, and a rod connected to the drive arm. The drive arm includes a fixed portion to which the rotating shaft is fixed, a first extension portion where the rod is connected, and a second extension portion extending on the opposite side of the first extension portion. The turbine housing is provided with a stopper with which the second extension portion abuts at the time when the valve body is distanced from the wastegate port due to a rotation of the rotating shaft in a valve-opening direction.

  • Patent number: 10415457
    Abstract: Techniques for setting a boost target for a turbocharged engine comprise (i) operating the engine in a scavenging mode such that opening of intake and exhaust valves of cylinders of the engine overlap and (ii) while transitioning the engine in/out of the scavenging mode: determining an engine torque request, creating a torque reserve by setting independent targets for throttle inlet pressure (TIP) and intake manifold absolute pressure (MAP), determining a target TIP based on a target total air charge, engine speed, and a previously-determined target engine volumetric efficiency (VE), controlling a wastegate valve based on the target TIP, determining a target MAP based on the engine torque request, and controlling a throttle valve based on the target MAP. During steady-state scavenging operation, the controller calculates a conventional target TIP based on the engine torque request and controls the wastegate valve based on the conventionally calculated target TIP.

  • Patent number: 10378470
    Abstract: Methods and systems are provided for providing passive boost pressure monitoring for slow response with higher confidence. A response time of a boost pressure feedback control loop following a boost pressure deviation that is triggered by either system disturbances or operator torque demand is monitored. Slow boost behavior is correlated with boost control degradation affecting drivability and emissions.
