Claim:
1. A power system, comprising: an intake gas cooler configured to receive a fresh intake gas for combusting in an engine and a recirculated exhaust gas expelled by the engine for re-combusting therein; a fresh intake gas passage configured to receive the fresh intake gas, a portion of the fresh intake gas passage being defined by the intake gas cooler; an exhaust gas recirculation (EGR) passage configured to route the recirculated exhaust gas, a portion of the EGR passage being defined by the intake gas cooler; an aftercooler positioned gaseously downstream of the fresh intake gas passage, and the aftercooler is positioned to receive only fresh intake gas; a circuit fluid passage configured to receive a circuit fluid, a portion of the circuit fluid passage being defined by the intake gas cooler, the portion of the circuit fluid passage being positioned so as to cool the fresh intake gas and the recirculated exhaust gas; a first heat transfer circuit comprising a first heat exchanger and a lube oil cooler fluidly coupled thereto, a portion of the first heat transfer circuit being defined by the circuit fluid passage, the lube oil cooler being configured to cool lube oil that circulates through the engine; and a second heat transfer circuit fluidly coupled to the engine and comprising a second heat exchanger, the second heat exchanger being configured to cool a second circuit fluid that cools a block and head of the engine, the first heat transfer circuit is separate and distinct from the second heat transfer circuit, such that the circuit fluid does not mix with the second circuit fluid.
