1. A fuel ejector assembly, comprising:
a nozzle structured to receive fuel from a fuel conduit and eject the fuel therethrough;
an exhaust gas recirculation (“EGR”) conduit structured to communicate a recirculated exhaust gas therethrough;
a mixing portion disposed downstream of the nozzle and the EGR conduit, the nozzle and the EGR conduit fluidly coupled to the mixing portion such that the mixing portion receives each of the fuel and the recirculated exhaust gas;
a diffuser disposed downstream of the mixing portion and structured to be fluidly coupled to an engine to communicate a mixture of the fuel and the recirculated exhaust gas to the engine; and
a bypass line fluidly coupled to the fuel conduit upstream of the nozzle, the bypass line structured to receive a portion of the fuel and communicate the portion of the fuel downstream of the diffuser and upstream of the engine.
