Abstract: A fuel ejector assembly includes a nozzle structured to receive fuel from a fuel conduit and eject the fuel therethrough, and an exhaust gas recirculation (“EGR”) conduit structured to communicate a recirculated exhaust gas therethrough. A mixing portion is 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 is disposed downstream of the mixing portion and is configured to be fluidly coupled to an engine to communicate a mixture of the fuel and the recirculated exhaust gas to the engine.
