Abstract
Methods and systems to provide compressed air to one or more air consumers external to the engine via exhaust gases of an internal combustion engine are presented. In one example, the exhaust gas may be routed to drive an air turbine of an air compression system. The air compressed at the compression system may be stored in a tank and/or provided to the one or more air consumers.
Claims20
A method for a vehicle, comprising:
- adjusting a number of engine cylinders combusting based on a torque demand and a compressed air request;
- and
- supplying exhaust gas from an engine to drive an air turbine of an air compression system, the air turbine coupled to a compressor via a gear system housed on a shaft, and providing compressed air to one or more air consumers external to the engine.
A method for a vehicle, comprising:
- in response to a request for compressed air based on a tank pressure of an air tank,
- suspending fuel injection and combustion in each cylinder of a first cylinder bank of an engine;
- routing air from the each cylinder of the first cylinder bank to an air turbine;
- and
- compressing ambient air via an air compressor coupled to the air turbine via a gear system housed on a shaft.

A system for a vehicle, comprising:
- an engine including a first cylinder bank and a second cylinder bank;
- a first exhaust passage of the first cylinder bank configured to supply exhaust gas to an air turbine via a diverter valve;
- an air compressor coupled to the air turbine via a gear system housed on a shaft;
- and
- an air tank configured to receive and store compressed air from the air compressor.
