Abstract: Water vapor is introduced into an inlet air stream (16) of an engine (12), for example, by a pervaporation process through a non-porous hydrophilic membrane (18). A water reservoir (20), which can contain contaminated water, provides a vapor pressure gradient across the hydrophilic membrane (18) into the inlet air stream (16), while the rate of delivery of the water vapor to a cylinder (38-40) is self-regulated by the rate of flow of air across the membrane. The hydrophilic membrane (18) therefore also filters the water from the water reservoir (20) to an extent that pure water vapor is provided to the air inlet stream (16). Delivery of water vapor can nevertheless be controlled using a hood (26) that slides over the hydrophilic membrane to limit its exposed surface area.

Abstract: A porous diffuser is disclosed. The porous diffuser can be in the form of a hose or other structure, the wall of the hose or structure having many small and irregularly shaped channels and pores that allow gas to seep out of the hose into the liquid. The diffuser receives air, oxygen or other gasses, and releases these gasses as bubbles into the liquid through the channels and pores. As the bubbles migrate in the liquid, they diffuse their gas into the liquid, as well a mix the liquid. The porous diffuser also provides for convenient methods to purge the system of liquid that has seeped into the diffuser during normal use and to retrieve the diffuser when maintenance, repair or replacement is required. An anchoring system can be incorporated with the porous diffuser to overcome buoyancy problems associated with gas in a liquid environment which can reduce or prevent proper gas distribution.
