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
An engine system comprising:
- a turbine driven indirectly by 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;
- 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;
- and
- a controller configured to generate a plurality of throttle control signals, each of the plurality of throttle control signals configured to control the flow of air to one of a plurality of cylinders.
An apparatus comprising:
- a communication interface electrically connected to a dual compressor turbocharger, the dual compressor turbocharger including a first compressor mounted to a shaft and coupled to an air supply and an air intake of the engine and including a second compressor mounted on the shaft and coupled to a fuel supply and a fuel supply rail of the engine;
- and
- a controller, wherein the controller is configured to generate a control signal for the dual compressor turbocharger based on sensor data and configured to generate a plurality of throttle control signals, each of the plurality of throttle control signals configured to control the flow of air to one of a plurality of cylinders.
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;
- 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;
- drawing fuel from the fuel supply rail;
- and
- generating a plurality of throttle control signals, each of the plurality of throttle control signals configured to control the flow of air to one of a plurality of cylinders from the air intake of the engine to mix with the fuel drawn from the fuel supply rail.
