Abstract: Selective catalytic reduction filter (SCRF) devices and systems incorporating the same are provided. Systems can include an exhaust gas source, an exhaust gas conduit capable of receiving an exhaust gas stream from the exhaust gas source, and an SCRF device in fluid communication therewith. The SCRF device can include a filter, a selective catalytic reduction (SCR) catalyst disposed on at least portion of the filter, and a NOx storage coating on at least a portion of the filter. The NOx storage coating can include one or more of palladium, barium, or cerium. The NOx storage coating can be biased towards the upstream side of the filter. The NOx storage coating can overlap a portion of the SCR catalyst. The system can further include a water-absorbing alkali oxide. The water-absorbing alkali oxide can be disposed within the SCRF device, the exhaust gas conduit, or in an upstream oxidation catalyst device.

Abstract: A method of controlling a concentration of hydrocarbons in exhaust gas from an internal combustion engine includes sensing an oxygen percentage of the flow of exhaust gas from the internal combustion engine and determining a concentration of hydrocarbons in the flow of exhaust gas. An engine control module may then adjust the sensed oxygen percentage of the exhaust gas based on the determined concentration of hydrocarbons in the flow of exhaust gas to define a corrected oxygen percentage. The control module may then control at least one of a hydrocarbon injection rate for in-cylinder combustion of the internal combustion engine, and a hydrocarbon injection rate for a post combustion exhaust gas treatment process, based on the corrected oxygen percentage, to control the concentration of hydrocarbons in the exhaust gas.

Abstract: A method for controlling re-circulation of exhaust gas (EGR) in an internal combustion engine includes receiving a signal indicative of an engine operating temperature and comparing the engine operating temperature to a first predetermined IEGR threshold. When the engine operating temperature is less than the first predetermined internal EGR threshold, a first internal EGR mode is activated, whereby engine emissions may be reduced or combustion stability may be enhanced. When the engine operating temperature is greater than the first predetermined internal EGR threshold, the first internal EGR mode is deactivated, and a second internal EGR mode is activated, whereby emissions may be reduced as exhaust system heating is accelerated. When the operating temperature is greater than the second temperature threshold, the second internal EGR mode may be deactivated a third mode may be enabled with only external EGR.
