The turbocharger further comprising a turbine driven by exhaust gases.
Claims20
A turbocharger, comprising:
- a compressor;
- a first turbine configured to drive the compressor, the first turbine configured to be driven by exhaust gases;
- a second turbine configured to drive the compressor;
- a nozzle;
- and
- a fuel supply configured to deliver engine fuel to the nozzle;
- wherein the second turbine is configured to be driven by fuel ejected from the nozzle.
A system, comprising:
- a turbocharger comprising a first turbine and a second turbine, wherein each of the first turbine and the second turbine are coupled to a compressor via a shaft;
- and
- an injector positioned to inject a medium into the turbocharger toward the second turbine.
A method for a turbocharger comprising a compressor, and first and second turbines configured to drive the compressor, wherein the first turbine is configured to be driven by exhaust gases, and the second turbine is configured to be driven by a medium ejected from a nozzle;
- the method, comprising:
- injecting the medium from the nozzle to drive the second turbine and spin up the compressor during an accelerator pedal tip-in.
