A method for an internal combustion engine includes the steps of collecting exhaust gas in a volume ( 902 ) and flowing exhaust gas out of the volume in a first and a second portions ( 904 ). The first portion forms a tailpipe gas stream ( 906 ), and the second portion forms an EGR gas stream ( 908 ). The tailpipe gas stream goes through a turbine ( 910 ). The EGR gas stream is catalyzed by an oxidizer coating in a heat exchanger, and thermal energy is transferred from the EGR gas stream to the tailpipe stream in the heat exchanger ( 916 ).
