Abstract
Methods and systems to provide compressed air via exhaust gases of an internal combustion engine are presented. In one example, a pump comprising two pistons is driven via engine exhaust gases. On piston within the pump moves in response to the exhaust gases while the other piston acts to compress air.
Claims20
A method for providing air power to one or more air consumers, comprising:
- supplying an exhaust gas from an internal combustion engine to a pump;
- and
- compressing air via the pump, where the pump includes two pistons and two cylinders.
(canceled)
A system for supplying compressed air from a vehicle, comprising:
- an internal combustion engine including an exhaust system;
- a pump in pneumatic communication with the exhaust system;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust a position of a piston of the pump via adjusting a position of a valve that selectively changes a direction of exhaust flow to the pump.
