Abstract: A method of increasing a weighting factor of an exponentially weighted moving averaging (“EWMA”) filter is provided. The method includes monitoring a data stream containing raw data values, and determining an EWMA value based on the data stream by an electronic control module. The method includes determining if the EWMA value is between a predetermined maximum fault threshold value and a predetermined minimum fault threshold value. The method includes increasing the weighting factor of the EWMA filter to more heavily weigh incoming raw data values of the data stream based on the difference between the first raw data value and a previously calculated filtered value exceeding the calibration value.

Abstract: A method of estimating a mass flow rate of nitrogen oxides in exhaust gas includes sensing a mass flow rate of a flow of exhaust gas from the engine. A nitrogen oxides base concentration for when the engine is operating at a reference state is defined, and a nitrogen oxides ratio for a current operating state of the internal combustion engine is calculated. The mass flow rate of the flow of exhaust gas, the nitrogen oxides base concentration, and the nitrogen oxides ratio for the current operating state of the engine are multiplied together to define an estimated value of the current mass flow rate of nitrogen oxides in the flow of exhaust gas from the engine. The estimated value of the mass flow rate of nitrogen oxides may be compared to the output from a nitrogen oxides sensor to determine proper functionality of the nitrogen oxides sensor.

Abstract: A method is disclosed for regulating an exhaust after-treatment (AT) system having a diesel particulate filter (DPF) in fluid communication with a diesel engine. The method includes detecting operation of the diesel engine during which the engine generates a flow rate of particulate matter (PM) directed into the DPF. The method also includes detecting a flow rate of PM exiting the DPF in response to the flow rate of PM directed into the DPF. The method additionally includes tracking the detected flow rate alongside a predicted PM flow rate for monitoring and comparison thereof. The method also includes pausing in time the tracking of the predicted flow rate, if the detected flow rate has experienced a decline. Furthermore, the method includes resuming tracking the predicted flow rate when the detected flow rate returns to a value before the decline and using such value to regulate operation of the AT system.

Abstract: A method for particulate filter performance monitoring in an exhaust gas treatment system is provided. The method includes monitoring a current received from a soot sensor in the exhaust gas treatment system and comparing the current to a soot sensor current threshold. Based on determining that the current is greater than or equal to the soot sensor current threshold, an accumulated engine out soot value is compared to an accumulated engine out soot threshold. A particulate filter fault is set based on determining that the accumulated engine out soot value is less than the accumulated engine out soot threshold. A monitoring system and an exhaust gas treatment system of an engine are also provided.
