Abstract
An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a generator, an electrically heated catalyst ('EHC') device, and a control module. The exhaust gas conduit is in fluid communication with, and is configured to receive an exhaust gas from the internal combustion engine. The generator operates at a generator speed to produce electrical power. The EHC device is in fluid communication with the exhaust gas conduit. The EHC device includes a monolith structure that is divided into a plurality of segments that define discrete resistive paths. The resistive paths are selectively connected to the generator for receiving electrical power. The control module is in communication with the EHC device, the generator, and the internal combustion engine. The control module includes control logic for determining the generator speed.
