Abstract
A method and system for the intake air separation within an internal combustion engine is disclosed. The disclosed embodiments of the intake air separation system include an intake air inlet adapted to receive substantially all of the intake air used in the combustion process for the engine and an intake air separation device in flow communication with the intake air inlet and adapted for separating substantially all of the intake air into a flow of the oxygen enriched air and a flow of nitrogen enriched air. The intake air separation system further includes a first outlet in fluid communication with the intake air separation device and adapted to receive a flow of the oxygen enriched air as well as a second outlet also in fluid communication with the intake air separation device and adapted to provide the flow of nitrogen enriched air to the intake manifold for use in the combustion process.
