Patent ID: 8601798

Claim:
A system for the treatment of exhaust gases, the system comprising: an internal combustion engine having at least one exhaust port; an exhaust aftertreatment system fluidly coupled to the at least one exhaust port and configured to accept exhaust gas flow from the engine, wherein the exhaust aftertreatment system includes a particulate filter configured to filter particulate matter from the exhaust gas; and a controller in communication with at least one of the engine and the exhaust aftertreatment system and configured to determine an actual temperature of the particulate filter during a regeneration process and analyze the actual temperature relative to a temperature deviation threshold, wherein the controller is configured to adjust the temperature deviation threshold in real time based at least in part on an operating condition of the engine; wherein the operating condition of the engine is based at least in part on a speed of the engine; wherein the controller is configured to determine a maximum temperature above a desired temperature and a minimum temperature below the desired temperature; wherein the temperature deviation threshold is defined by one or more of the desired temperature, the maximum temperature, and the minimum temperature.
