Abstract: A heat exchanger of motor vehicle processes a gas flow including combustion exhaust gas. Combustion by-product deposit build-up within the heat exchanger is reduced by maintaining a minimum gas flow velocity within the heat exchanger by reducing heat exchanger total gas flow cross section to locally increase a gas flow velocity.

Abstract: A heat exchanger device for an exhaust gas recirculation system of an internal combustion engine includes a heat exchange device including a first surface and a second surface. The first surface is in fluid contact with a recirculated portion of exhaust gas flowing in an exhaust system and the second surface is in fluid contact with a second fluid. The first surface is subjected to a surface treatment effective to reduce adhesive properties that relate to surface tension of particulate matter that precipitates from the recirculated portion of the exhaust gas.

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.
