Abstract
The engine emissions control system using an ion transport membrane incorporates an ion transport membrane unit into a closed, recirculating intake and exhaust system in the engine. The unit has a housing defining an air intake channel separated from an exhaust gas recirculation channel by an ion transport membrane. The membrane is permeable to oxygen, but is impermeable to nitrogen, water and carbon dioxide. Oxygen drawn from ambient air in the air intake channel is transported through the membrane to enrich the flow of exhaust gases in the exhaust gas recirculation channel, which is transported through a conduit to the engine intake for combustion of hydrocarbon fuel. The oxygenated exhaust gases may include uncombusted fuel or incomplete combustion products. Exhaust and intake accumulators may smooth the gas pulses. The accumulated or excess carbon dioxide and water in the exhaust is recovered from the system into onboard storage tanks or containers.
