A power plant includes an engine configured to receive charge air and produce exhaust. A first turbo machine is configured to be driven by the exhaust and drive a compressor that receives air. The compressor is configured to produce the charge air. A second turbo machine is configured to receive the charge air and rotationally drive a pump in response thereto. The pump is configured to receive an EGR from the exhaust and introduce the pumped EGR to the charge air. The power plant also includes an exhaust gas recirculation passage. The second turbo machine includes a turbine rotationally coupled to the pump. The turbine has an expanded air passage, and the pump is arranged in the exhaust gas recirculation passage. A pre-cooler is arranged in the expanded air passage and in the exhaust gas recirculation passage upstream from the pump. |
