Abstract

An exhaust gas treatment system for an internal combustion engine is provided comprising an exhaust gas conduit, a particulate filter ('PF') device, a hydrocarbon source and an electronic control module including operative logic which when implemented. The PF has a filter structure for removal of particulates in the exhaust gas and is selectively regenerated based on an amount of particulates trapped within the filter structure of the PF device. The control module is in communication with the internal combustion engine and the hydrocarbon source, and receives a regeneration signal indicating the amount of particulates trapped within the filter structure of the PF device. The electronic control module includes control logic for monitoring the internal combustion engine prior to a regeneration event. The electronic control module includes control logic for determining a plurality operating parameters of the internal combustion engine based on the monitoring.
