Abstract
A method for providing intake air to an engine in a vehicle comprises delivering compressed fresh air and EGR to the engine via first and second throttle valves coupled to an intake manifold of the engine. During a higher engine-load condition, an EGR exhaust flow is cooled in a heat exchanger and the cooled EGR exhaust flow is admitting to the intake manifold. During a lower engine-load condition, fresh air is warmed in the heat exchanger, and the warmed fresh air is admitted to the intake manifold.
