Abstract

An exhaust treatment system (14) for a power system (10) is disclosed. The exhaust treatment system includes an exhaust conduit (18) directing exhaust gas (16) produced by the power system towards at least one exhaust treatment device (32). The exhaust treatment system may also include a substrate (42) positioned within an enclosure (20) of the at least one exhaust treatment device. The exhaust conduit may be configured to preheat the substrate with the exhaust gas prior to directing the exhaust gas into the enclosure.
