Abstract
A vehicular heat exchanger processes a exhaust gas recirculation flow. A method to manage combustion by-product contaminant deposits within the heat exchanger includes repeatedly cycling a flow control device controlling the exhaust gas recirculation flow through the heat exchanger from an original position to an intermediate position and back to the original position. The original position is determined based upon a required exhaust gas recirculation flow into an intake manifold.
