1. A power system for a work vehicle, comprising:
a compression ignition engine configured to receive and combust intake gas to generate mechanical power and exhaust;
an EGR (exhaust gas recirculation) arrangement configured to receive a portion of the exhaust generated by the compression ignition engine as EGR gas;
a first mixer configured to mix a first portion of the EGR gas and charge air as mixed gas;
an intake heat exchanger with coolant circulating therein and configured to exchange heat between the coolant and the charge air or the mixed gas;
a second mixer configured to mix a second portion of the EGR gas and the mixed gas as the intake gas; and
an intake manifold configured to direct the intake gas from the second mixer into the compression ignition engine for combustion.
