Abstract
This invention provides a method and system for providing an oxygen-enriched air stream to the cabin and/or internal combustion engine of a vehicle. The benefits of such an approach include increased fuel efficiency and reduced emissions in the internal combustion engine and increased driver alertness and comfort for the vehicle operator. The oxygen-enriched air stream is provided by a membrane separation system, a pressure swing adsorption system, vacuum swing adsorption, or other methods. The delivered oxygen-enriched air is controlled to a prescribed level using sensors, valves, and controllers.
Claims25
A process for providing elevated oxygen concentrations to a vehicle, the process comprising:
- intaking ambient air from external to the vehicle through a first air intake, establishing an ambient air stream;
- separating the ambient air stream into a stream of oxygen-enriched air and a stream of oxygen-depleted air;
- at a source, creating a modified oxygen-enriched air stream from the stream of oxygen-enriched air and ambient air from a second air intake;
- an oxygen concentration controller managing to divert the modified oxygen-enriched air stream from the source into a dedicated engine modified oxygen-enriched air stream and a dedicated cabin modified oxygen-enriched air stream;
- introducing a controlled amount of the dedicated engine modified oxygen-enriched air stream into a combustion chamber of an engine of the vehicle and increasing an oxygen concentration in the combustion chamber during a combustion cycle to a concentration greater than that of ambient air external to the vehicle;
- introducing a controlled amount of the dedicated cabin modified oxygen-enriched air stream into a vehicle cabin and increasing an oxygen concentration in the vehicle cabin to a desired concentration threshold greater than that of ambient air external to the vehicle;
- and
- outputting exhaust gases.
