Abstract:
A method for exhaust aftertreatment includes determining a diagnostic condition with respect to a threshold diagnostic condition, determining an SCR efficiency as a ratio of a readout of a first NOx sensor at a first NOx sensing position with respect to a readout of a second NOx sensor at a second NOx sensing position, the first NOx sensing position located about an engine out area within an exhaust stream before a DOC and the second NOx sensing position located about an output of an SCR device within the exhaust stream; and comparing the SCR efficiency to a threshold SCR efficiency range. If the SCR efficiency is less than the threshold SCR efficiency range, then trigger DOC failure for NO oxidation, and if the SCR efficiency is greater than or equal to the threshold SCR efficiency range, then DOC is determined to be operating within specifications.

Claim (Index 11):
The method of  claim 2 , wherein the range of values for the exhaust flow rate is from about 20 to about 40 g/s.
