Abstract
Methods and systems are provided for a turbocharger. In one example, the turbocharger comprises an injector configured to inject a medium therein, wherein the injector is configured to inject the medium toward a turbine of the turbocharger. The turbocharger further comprising a turbine driven by exhaust gases.
Claims17
A turbocharger of an engine system, the 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 and injectors of an engine, wherein fuel in the second turbine is relayed directly to the injectors without returning to a fuel system;
- wherein the second turbine is configured to be driven by fuel injected from the nozzle, and the turbocharger is configured to drain fuel to a fuel injector pump.
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 fuel from an engine fuel system into the turbocharger toward the second turbine, the engine fuel system further coupled to injectors of an engine, and wherein an amount of fuel injected toward the second turbine is based on a fuel tank volume.
A method for a turbocharger of an engine system, the 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 fuel ejected directly from a nozzle;
- the method, comprising:
- flowing fuel from a fuel system of an engine to the nozzle, the fuel system coupled to each of engine fuel injector and the nozzle;
- injecting fuel from the nozzle to drive the second turbine and spin up the compressor during an accelerator pedal tip-in;
- and
- supplying exhaust gas to the first turbine after injecting fuel to drive the second turbine.
