    Abstract: An exhaust treatment system includes a particulate filter having a filter substrate configured to trap soot contained in exhaust gas. A regeneration system is configured to perform a regeneration operation that regenerates the particulate filter by burning away soot stored in the filter substrate. A control module is in electrical communication with the regeneration system to generate a first control signal that initiates the regeneration operation based on a comparison between at least one operating condition of the exhaust treatment system and a threshold value. The control module generates a second control signal in response to detecting at least one diagnostic signal. The second control signal initiates the regeneration operation independently of the comparison.

    Abstract: An exhaust gas treatment system includes a particulate filter to collect particulate matter from exhaust gas flowing therethrough. A regeneration module performs a regeneration operation that regenerates the particular filter. The regeneration operation generates an exothermic event which heats the particulate filter above a target temperature that burns the particulate matter. At least one temperature sensor is disposed adjacent the particular filter to determine at least one temperature of the exhaust gas. The exhaust gas treatment system further includes a temperature diagnostic module to determine a temperature profile of the particulate filter based on the temperature of the exhaust gas. The temperature diagnostic module further determines a temperature deviation of the particulate filter based on a comparison between the temperature profile and a target temperature. The temperature diagnostic module diagnoses the regeneration operation based on a plurality of temperature deviations and a selected time period.

    Abstract: A system and method for initiating an engine after-run state and controlling a nitrogen oxide sensor self-diagnostic tool are provided. The system may include an internal combustion engine, an exhaust system, a selective catalytic reduction (SCR) device and at least two NOx sensors to measure the efficiency of the SCR device and a controller or host machine. The controller, via the present method, executes a first control action to disable the self-diagnostic tool when one of an occurrence of a particulate filter regeneration event and a non-occurrence of a calibration threshold is detected. The controller executes a second control action, initiating an engine after-run state and enabling the self-diagnostic tool when one of a non-occurrence of a particulate filter regeneration event and an occurrence of the calibration threshold is detected.

    Abstract: An exhaust gas treatment system includes a particulate filter to collect particulate matter from exhaust gas flowing therethrough. The particulate filter realizes a pressure thereacross in response to the exhaust gas flow. A delta pressure sensor determines a first pressure upstream from the particulate filter and a second pressure downstream from the particulate filter. A delta pressure module is in electrical communication with the delta pressure sensor. The delta pressure module determines a pressure differential value based on a difference between the first pressure and the second pressure and generates a diagnostic signal based on a plurality of the pressure differential values and a predetermined time period.
