Claims20
A multi-spool turbocharger, comprising:
- a compressor including a plurality of compressor spools;
- and
- a turbine including a plurality turbine spools that can rotate in a single-rotation or counter-rotating directions.
A multi-spool turbocharger, comprising:
- a compressor including at least first and second compressor spools;
- a turbine including at least first and second turbine spools, where the first compressor spool is coupled to the second turbine spool via a first shaft rotatable in a first direction and the second compressor spool is coupled to the first turbine spool via a second shaft rotatable in a second direction opposite the first direction.
A method for operating a multiple spool turbocharger in an engine, comprising:
- counter-rotating first and second compressor spools and first and second turbine spools of the turbocharger;
- and
- during a first condition, supplying compressed air from the first compressor spool to the engine;
- during a second condition, supplying compressed air from the second compressor spool to the engine;
- during a third condition, supplying compressed air from both the first and second compressor spools to the engine.
