    Abstract: An exemplary embodiment is a system, including an internal combustion engine fluidly coupled to an exhaust gas flowpath, an aftertreatment system disposed in the exhaust gas flowpath, where the aftertreatment system includes a NOx reduction catalyst. The exemplary system includes a processing subsystem having a controller, where the controller includes modules structured to functionally execute operations for determining a catalyst degradation. The modules include a test conditions module, a testing module, a monitoring module, and a catalyst aging module. The test conditions module interprets a test conditions event occurrence for the NOx reduction catalyst, the testing module commands a catalyst efficiency test in response to the test conditions event occurrence, the monitoring module interprets operating condition(s) indicative of a NOx conversion efficiency during the catalyst efficiency test, and the catalyst aging module determines a catalyst aging value in response to the at least one operating condition.

    Abstract: A method includes determining whether a urea refill event is detected, and clearing a quality accumulator value and clearing a latching abort command. The method includes determining whether urea fluid quality check abort conditions are met, and clearing the urea quality accumulator, latching the abort command, and exiting the reductant fluid quality check. In response to the abort conditions not being met, incrementing the urea quality accumulator according to an amount of urea being injected, and comparing the accumulated urea quantity to a low test threshold. The method includes, in response to the accumulated urea quantity being greater than the low test threshold, comparing the accumulated urea quantity to a high test threshold, and in response to the urea quantity being greater than the high test threshold, determining whether the a NO x exceedance is observed and clearing a urea quality error in response to the NO x exceedance not being observed.

    Abstract: In one embodiment, an apparatus is disclosed for heating a reductant delivery line (180) using coolant from an internal combustion engine (110) where the reductant delivery line receives reductant (200) from a reductant tank (166) and a portion (210) of a coolant line (192) is positioned within the reductant tank. The apparatus includes a coolant temperature module (300) that is configured to determine a reductant tank outlet coolant temperature target (310). Additionally, the apparatus includes a coolant flow rate module (320) that is configured to generate a coolant valve flow rate command (340) and transmit the command to a coolant valve (196).
