SYSTEM INCLUDING OXYGEN SEPARATION DEVICE
First Claim
1. A system comprising:
- an internal combustion engine including a combustion gas inlet;
an oxygen separation device positioned to be heated with heat generated by the internal combustion engine during operation of the internal combustion engine;
the oxygen separation device including a casing and a module in the casing;
the casing having an air inlet, a retentate outlet, and a permeate outlet, the permeate outlet being in fluid communication with the combustion gas inlet of the internal combustion engine;
the module including an oxygen ion transport membrane separating the retentate outlet and the permeate outlet; and
a heat absorber between the casing and the module.

Abstract
An oxygen separation device includes a substrate and an oxygen ion transport membrane supported on the substrate. The substrate has an air inlet end and a retentate outlet end. An intake air passageway extends through the substrate from the air inlet end to the retentate outlet end. The oxygen ion transport membrane is between the substrate and the intake air passageway and is adapted to separate oxygen atoms from the air in the intake air passageway and to transport the oxygen atoms to the substrate. The oxygen separation device collects the oxygen from the substrate for supply to an internal combustion engine for use as the gas of the gas-fuel mixture.
