Title: Engine system having carbon foam exhaust gas heat exchanger

Abstract

An engine system includes an engine such as a compression ignition internal combustion engine, including a heat exchanger in an exhaust system thereof. The heat exchanger including at least one carbon foam block for cooling exhaust gas with cooling air. An exhaust system segment includes a carbon foam based heat exchanger configured to exchange heat between exhaust gas and cooling air at least in part via the carbon foam.
