An in- let air management system includes a membrane-based separator and an exhaust gas recirculation flowpath that cooperate to deliver a nitrogen 145 A _ enriched air stream to the engine to help reduce exhaust gas emissions, while a segregated portion of the incoming air can form an oxygen en- riched air stream that can be used for various engine load conditions, as well as for supplemental air for a cabin or related passenger compartment rii5F within a vehicle that is powered by the engine. During an increase in en- gine load not associated with the cold start and warm-up conditions, the nitrogen enriched air stream may come from one or both of the separator and the nitrogen enriched combustion product stream from the exhaust gas recirculation flowpath. 135 116, 05A 1 GS1IEA L L 1 ar s 5 , 1: 105 115, \ 05B 1,5115NEA 125 110 CABIN INPUT INTAKE CONTROL COMBUSTION DATA _r H 115EG ( 5- 1 115 000 10 FIG. 2 15c 20 [Continued on next page] WO 2018/183103 A4 MIDEDIM011010EIREE3111111401011100111010H1 TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
