Patent ID: 7337770

Claim:
A system comprising: an oxygen-enrichment reverse osmosis unit including a reverse osmosis apparatus comprising a pressurized air inlet, an oxygen-enriched outlet, an oxygen-reduced outlet, and a membrane, the membrane separating the oxygen-enriched air and oxygen-reduced air, the reverse osmosis unit is adapted to accept pressurized ambient air into the pressurized air inlet and provide oxygen-enriched air out of the oxygen-enriched outlet and oxygen-reduced air out of the oxygen-reduced outlet, the oxygen-enriched air having a greater concentration of oxygen as the ambient air; and an internal combustion engine comprising an intake is in fluid communication with a combustion chamber, the oxygen-enriched outlet of the reverse osmosis unit is in fluid communication with the intake, wherein the reverse osmosis unit further comprises a compressor having a compressor inlet and a compressor outlet, the compressor adapted to accept ambient air into the compressor inlet and produce a supply of pressurized air to the pressurized air inlet of the reverse osmosis apparatus, wherein the compressor comprises a compressor drive shaft adapted to drive the compressor so as to deliver pressurized air at a predetermined pressure to the pressurized air inlet of the reverse osmosis apparatus.
