Abstract
A dual compressor turbocharger includes two compressors. One compressor supplies fuel pressure, and one compressor supplies air pressure. The dual compressor turbocharger includes a turbine driven by exhaust of an engine and a shaft coupled to the turbine. The first compressor is mounted on the shaft and includes a first inlet coupled to an air supply and a first outlet coupled to an air intake of the engine. The second compressor is mounted on the shaft and includes a second inlet coupled to a fuel supply and a second outlet coupled to a fuel supply rail of the engine.
Claims20
A turbocharger comprising:
- a turbine driven by exhaust of an engine;
- a shaft coupled to the turbine;
- a first compressor mounted on the shaft and having a first inlet coupled to an air supply and a first outlet coupled to an air intake of the engine;
- and
- a second compressor mounted on the shaft having a second inlet coupled to a fuel supply and a second outlet coupled to a fuel supply rail of the engine.
An internal combustion engine comprising:
- a fuel supply rail configured to deliver fuel to the internal combustion engine;
- an air intake chamber configured to deliver air to the internal combustion engine;
- a turbine driven by exhaust of the internal combustion engine;
- a shaft coupled to the turbine;
- a first compressor mounted on the shaft and having a first inlet coupled to an air supply and a first outlet coupled to the air intake of the engine;
- and
- a second compressor mounted on the shaft having a second inlet coupled to a fuel supply and a second outlet coupled to the fuel supply rail of the engine.
A method comprising:
- driving a turbine from exhaust of an engine;
- rotating a shaft coupled to the turbine;
- generating air pressure by a first compressor mounted on the shaft and having a first inlet coupled to an air supply and a first outlet coupled to an air intake of the engine;
- and
- generating fuel pressure by a second compressor mounted on the shaft having a second inlet coupled to a fuel supply and a second outlet coupled to a fuel supply rail of the engine.
