Exhaust gas cooling is accomplished by the flow of exhaust gases through the EGR cooler tubes. The EGR cooler core then transfers the heat removed from the exhaust gases to the engine coolant. The cooled exhaust gases are then mixed with incoming air from the Charge Air Cooler (CAC) before being sent to the intake manifold. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
