ABSTRACT:
A vehicle thermal management system includes an exhaust gas cooler configured to receive exhaust gas from the engine and to cool the exhaust gas before it is recirculated back into the engine. A valve is located downstream from the exhaust gas cooler, and is operable to control the amount of exhaust gas passing through the exhaust gas cooler. Intake air mixes with the exhaust gas downstream from the first valve. The mixed gas is then cooled by a mixed gas cooler before it enters the engine intake manifold. A coolant is circulated through the mixed gas cooler and a heat exchanger. The mixed gas rejects heat to the coolant via the mixed gas cooler, and the coolant rejects heat to the ambient air via the heat exchanger.
