Abstract
Exemplary methods, devices and/or system for enhancing engine performance through use of one or more compressors and/or one or more turbines. An exemplary system includes an electric compressor to boost intake charge pressure supplied to an internal combustion engine; an electric turbine to generate electrical power from exhaust received from the internal combustion engine; and an electric power control to provide electrical power from a power storage to the electric compressor upon a request for boost and to provide electrical power generated by the electric turbine to the electric compressor after a request for boost and upon a depletion of the power storage to a predetermined power storage level. Various other exemplary methods, devices and/or systems are also disclosed.
Claims37
A method comprising:
- receiving a request for increased output of an internal combustion engine;
- responsive to the request, providing stored power to an electric compressor unit for approximately three seconds or less to thereby increase intake charge pressure to the internal combustion engine;
- generating electrical power using an electric turbine unit configured to extract energy from exhaust produced by the internal combustion engine;
- and
- providing the generated electrical power to one or more members selected from the group consisting of the electric compressor unit and a power storage.
An electric compressor for boosting intake charge supplied to an internal combustion engine, the electric compressor comprising:
- a compressor operatively coupled to a rotatable shaft;
- an electric motor operatively coupled to the rotatable shaft;
- a power storage configured to provide stored electrical power to the electric motor wherein the power storage comprises one or more supercapacitors;
- and
- a power input configured to receive electrical power from a power source to accomplish one or more tasks selected from the group consisting of charging the one or more supercapacitors and providing electrical power to the electric motor.
An apparatus comprising:
- an electric compressor to boost intake charge pressure supplied to an internal combustion engine;
- an electric turbine to generate electrical power from exhaust received from the internal combustion engine;
- and
- an electric power control to provide electrical power from a power storage to the electric compressor for approximately three seconds or less upon a request for boost and to provide electrical power generated by the electric turbine to the electric compressor after a request for boost and upon a depletion of the power storage to a predetermined power storage level.
