ABSTRACT:
A mixer assembly (204, 603) for mixing intake air from an intake system (124) with exhaust gas from an exhaust gas recirculation system (134) to yield a mixture stream includes an intake air conduit (202, 700) having an inlet (206, 706) fluidly connected to the intake system. The mixer assembly (204, 603) also includes a mixer (200, 600) having an inlet (208, 702) fluidly connected to the exhaust gas recirculation system (134). The mixer (200, 600) is at least partially disposed in the intake air conduit (202, 700) and includes an outer pipe (203, 604) and a dividing portion (217, 602) disposed within the outer pipe. The dividing portion (217, 602) divides a first passage (216, 612) from at least one second passage (218, 608), the first passage having an outlet (216′, 612′) that is at a first height, and the second passage having an outlet (218′, 608′) that is at a second height.
