Abstract
An exemplary system for an internal combustion engine includes an exhaust turbine operably coupled to a generator, an intake air compressor operably coupled to an electric motor and mechanically decoupled from the exhaust turbine and a controller to direct electricity generated by the generator to one or more members of the group consisting of the electric motor, an additional electric motor, and a power storage. Various other exemplary technologies are also disclosed.

A system for an internal combustion engine comprising:
- an exhaust turbine operably coupled to a generator;
- an intake air compressor operably coupled to an electric motor and mechanically decoupled from the exhaust turbine;
- an additional electric motor;
- a linkage to link the additional electric motor to a drivetrain drivable by the internal combustion engine;
- and
- a controller to direct electricity generated by the generator to one or more members of the group consisting of the electric motor, the additional electric motor, and a power storage.
A system for a normally aspirated internal combustion engine of a hybrid vehicle, the system comprising:
- an exhaust turbine operably coupled to a generator wherein the exhaust turbine comprises a variable geometry turbine;
- an electric motor;
- a linkage to link the electric motor to a drivetrain drivable by the normally aspirated internal combustion engine;
- and
- a controller to direct electricity generated by the generator to one or more members of the group consisting of the electric motor and a power storage and to control the geometry of the variable geometry turbine.
A hybrid vehicle comprising:
- a system for an internal combustion engine that comprises
