Abstract: An engine exhaust system includes an exhaust pipe assembly having an engine exhaust system inlet configured to receive engine exhaust and an engine exhaust system outlet. The system includes a first selective catalytic reduction (SCR) catalyst device positioned downstream in exhaust flow from the engine exhaust system inlet. The first SCR catalyst device includes a substrate with a metallic catalyst coated on the substrate. An electric heater is configured to heat the metallic catalyst. A second SCR catalyst device is positioned downstream in engine exhaust flow from the first SCR catalyst device and upstream of the engine exhaust system outlet. The first SCR catalyst device and the exhaust pipe assembly define an empty chamber between the substrate and the second SCR catalyst device. Engine exhaust flows directly from the substrate to the second SCR catalyst device through the empty chamber.

Abstract: An exhaust system for a lean-burn internal combustion engine is described, and includes an injection system for injecting reductant into an exhaust gas feedstream upstream of a selective catalytic reduction device (SCR). A control method for controlling the injection system includes determining an upstream NOx gas concentration upstream of the SCR device, determining a measured downstream NOx gas concentration based upon a signal output from a sensor configured to monitor NOx gas concentration downstream of the SCR device, and determining an estimated downstream NOx gas concentration based upon an executable model. A first correlation between the upstream NOx gas concentration and the measured downstream NOx gas concentration is determined, and a second correlation between the upstream NOx gas concentration and the estimated downstream NOx gas concentration is determined. The reductant injection is controlled based upon the first and second correlations.

Abstract: A method for implementing particulate filter regeneration management is provided. The method includes determining a presumptive deviation between a particulate model and actual particulate level conditions of the particulate filter. The presumptive deviation is determined from identification of an occurrence of extended parking, a passive regeneration, residual particulates, and a pressure signal. Each of the extended parking, passive regeneration, residual particulate, and pressure signal is specified by a respective particulate model deviation type. The method also includes selectively controlling current to at least one zone of a plurality of zones of an electric heater to initiate a regeneration event based on the presumptive deviation, and estimating the particulate level in the particulate filter once the regeneration event is complete.

Abstract: An exhaust gas treatment system includes a SCR device that stores a reductant that reacts with the NOx emissions and a reductant supply system to inject the reductant according to a reductant load model. At least one temperature sensor or model generates a temperature signal indicating an SCR temperature of the SCR device. The exhaust gas treatment system further includes a control module in electrical communication with the reductant supply system. The control module is configured to determine an amount of reductant that slips from the SCR device based on the at least one temperature signal and the rate of change of the SCR temperature. The control module further determines a correction factor based on the amount of slipped reductant to modify the reductant load model.

Abstract: A method of determining aging of a diesel oxidation catalyst (DOC) in an engine exhaust system includes receiving a first sensor signal from a first nitrogen oxides (NOx) sensor positioned in exhaust flow upstream of the DOC. The first sensor signal is indicative of an amount of NOx in the exhaust flow upstream of the DOC. The method further includes receiving a second sensor signal from a second NOx sensor positioned in the exhaust flow downstream of the DOC. The second sensor signal is indicative of an amount of NOx downstream of the DOC. A difference between the first sensor signal and the second sensor signal is calculated by a controller. A DOC aging level based on a predetermined correlation between the difference and DOC aging can then be determined by the controller if at least one predetermined operating condition is satisfied.

Abstract: An exhaust aftertreatment system for an internal combustion engine includes a selective catalytic reduction (SCR) device, an injection system disposed to inject reductant into the exhaust pipe upstream of the SCR device. A single ammonia sensor is disposed to monitor an exhaust gas feedstream downstream of the SCR device. A controller is in communication with the single ammonia sensor and the internal combustion engine and operatively is connected to the injection system. The controller includes an instruction set that is executable to monitor, via the single ammonia sensor, a magnitude of ammonia in the exhaust gas feedstream downstream of the SCR device and determine NOx efficiency of the SCR device based upon the magnitude of ammonia in the exhaust gas feedstream downstream of the SCR device. A fault is detected in the SCR device based upon the NOx efficiency.
