    摘要： A method for indicating a non-urea reductant fault in a powertrain including an internal combustion engine and an aftertreatment system having an aftertreatment device utilizing a catalyst to convert NOx includes monitoring a NOx content exiting the aftertreatment system subsequent to a powertrain start-up event through a test span, monitoring a measure of NOx content entering the aftertreatment system subsequent to a powertrain start-up event through the test span, and determining a measure of NOx conversion accomplished in the aftertreatment device based upon the NOx content exiting the aftertreatment system and the measure of NOx content entering the aftertreatment system. The method includes, through the test span, comparing the measure of NOx conversion determined at a start of the test span to the measure of NOx conversion at a later time within the test span. A non-urea reductant fault is indicated based upon the comparing identifying a reduction in NOx conversion accomplished in the aftertreatment device between the start of the test span and the later time within the test span.

    摘要： A method for assessing NO2 generation efficiency in a diesel engine after-treatment (AT) system having a diesel oxidation catalyst (DOC) downstream of the engine generating the NO2 and a selective catalytic reduction (SCR) catalyst downstream of the DOC converting NOX with the aid of the NO2. Engine exhaust gas flow is passed into the AT system and a reductant is injected into the gas flow between the DOC and the SCR catalyst. SCR inlet gas flow temperature is monitored during transient engine operation and DOC inlet and SCR catalyst outlet NOX concentrations are detected when the SCR catalyst inlet gas flow temperature is in a predetermined range. SCR catalyst NOX conversion efficiency is determined using the detected DOC inlet and SCR catalyst outlet concentrations of NOX. Additionally, whether the NO2 generation efficiency is at or above threshold efficiency is assessed by comparing the determined and threshold NOX conversion efficiencies.
