Abstract
A turbocharger is provided herein. The turbocharger includes a housing and an adjustable core at least partially circumferentially surrounded by the housing, the adjustable core having a turbine rotor coupled to a compressor rotor via a shaft. The turbocharger further includes an adjustment mechanism coupled to the adjustable core configured to adjust an axial position of the housing relative to the adjustable core in response to adjustment commands.
Claims20
A turbocharger comprising:
- a housing;
- an adjustable core at least partially circumferentially surrounded by the housing, the adjustable core comprising:
- a turbine rotor coupled to a compressor rotor via a shaft;
- and
- an adjustment mechanism coupled to the adjustable core configured to adjust an axial position of the housing relative to the adjustable core in response to adjustment commands.
2 more elements
A turbocharger comprising:
- a housing;
- an axially adjustable core circumferentially surrounded by the housing, the core including a turbine rotor coupled to a compressor rotor via a shaft, a compressor flow guide fluidically coupled between a volute and a compressor rotor, and a turbine flow guide fluidically coupled between a first and second turbine scroll and a turbine rotor.
A turbocharger comprising:
- a housing including a compressor volute configured to receive intake air from a compressor rotor and a first and second turbine scroll configured to direct exhaust gas to a turbine rotor;
- an adjustable core configured to move in an axial direction relative to the housing, the adjustable core comprising:
- a central core section including a shaft rotatably coupling the turbine rotor to the compressor rotor;
- a first peripheral core section including a compressor flow guide configured to direct airflow into the compressor volute from the compressor rotor;
- a second peripheral core section including a turbine flow guide configured to direct exhaust gas flow from the first and second turbine scrolls to the turbine rotor;
- an adjustment mechanism coupled to the adjustable core configured to adjust the axial position of the housing relative to the adjustable core in response to adjustment commands.
3 more elements
A turbocharger control method, comprising:
- adjusting one or more of compressor outlet flow and turbine inlet flow of the turbocharger via axially sliding a shaft coupling a compressor rotor and a turbine rotor within a fixed housing.
