Abstract
A marine engine system includes a marine engine, a turbocharger comprising a compressor, an air valve positioned in a flow path connecting the compressor and a mixing chamber to split flow between an intake air stream and a recovered air stream directed to a separation unit, an air operated compressor to generate a separator feed stream by increasing the pressure of the recovered air stream, the separation unit configured to concentrate nitrogen from the separator feed stream to generate a nitrogen-enriched air stream and a nitrogen-depleted air stream, a mixing chamber to combine the nitrogen-enriched air stream and the intake air stream to generate a nitrogen-enriched intake air stream, and a controller communicatively coupled to the air valve to direct the air valve to variably adjust the split between the intake air stream and the recovered air stream.
