    Abstract: A method for determining an over-temperature condition in an exhaust gas treatment system is provided. The method compares a current soot load in a particulate filter with a threshold soot load. The method compares each of a plurality of temperatures sensed by a plurality of temperature sensors with a threshold temperature. Based on determining that the current soot load in a particulate filter of the exhaust gas treatment system exceeds a threshold soot load and that one of the plurality of temperatures exceeds the threshold temperature, the method determines that the exhaust gas treatment system is in an over-temperature condition. Based on determining that the current soot load in the particular filter does not exceed the threshold soot load and that two or more of the plurality of temperatures exceed the threshold temperature, the method determines that the exhaust gas treatment system is in an over-temperature condition.

    Abstract: A vehicle and a method of updating efficiency of a selective catalytic reduction filter (SCRF) of an exhaust treatment system of the vehicle are disclosed. The method includes obtaining an initial calculated efficiency of the SCRF, via a controller, regarding one of a NOx conversion, a reductant absorption, a reductant desorption and a reductant oxidation. The method also includes determining a soot mass estimate in the SCRF representative of an amount of soot collected inside the SCRF and determining a soot correction factor from the soot mass estimate. The method further includes calculating, via the controller, an updated efficiency value of the SCRF by multiplying the soot correction factor and the initial calculated efficiency to update efficiency of the SCRF.

    Abstract: An exhaust treatment system configured to treat exhaust gas generated by an internal combustion engine includes a reductant delivery system that injects a reductant solution into an exhaust gas. A selective catalyst reduction (SCR) device reacts with the reductant solution to reduce NOx from the exhaust gas. A control module is in electrical communication with the SCR device and the reductant delivery system. The control module determines at least one of an injection status of the reduction delivery system and a performance of the SCR device. The control module further determines at least one debounce time for delaying diagnosis of a NOx sensor based on at least one of the injection status and the performance of the SCR device.

    Abstract: An exhaust treatment system includes an SCRF device, a reductant delivery system, and an SCR storage module. The SCRF device includes a filter portion having a washcoat formed thereon that defines a washcoat thickness (WCT). The reductant delivery system is configured to inject a reductant that reacts with the washcoat based on a reductant storage model. The SCR storage module is in electrical communication with the reductant delivery system to provide the reductant storage model the amount of reductant to be injected based on the reductant storage model. The exhaust treatment system further includes a WCT compensation module configured to electrically communicate a WCT compensation value to the SCR storage module. The SCR storage module modifies the reductant storage model according to the WCT compensation value such that the amount of ammonia that slips from the SCRF device is reduced thereby increasing a storage efficiency of the SCRF device.

The reductant delivery system is configured to inject a reductant that reacts with the washcoat.

The reductant storage module adjusts the setpoint according to the WCT compensation value such that the amount of ammonia that slips from the SCRF device is reduced as compared to the first setpoint.
