Abstract

One exemplary embodiment may include an internal combustion engine breathing system (10). The internal combustion engine breathing system (10) may include an exhaust passage (24), an intake passage (26), a turbocharger (28), an aftertreatment device (16), and an exhaust gas recirculation (EGR) assembly (14). The EGR assembly (14) may include a first EGR passage (46) communicating with the exhaust passage (24) at a first location (58) upstream of the aftertreatment device (16), and may include a second EGR passage (48) communicating with the exhaust passage (24) at a second location (60) downstream of the aftertreatment device (16). The EGR assembly (14) may also include one or more valve(s) (52, 68, 70) that may regulate fluid-flow in the first and/or second EGR passage (46, 48).
