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.

摘要： An exhaust gas treatment system for an internal combustion engine is provided having an exhaust gas conduit, a diesel exhaust fluid (“DEF”) source, a selective catalytic reduction (“SCR”) device, a NOx sensor, and a control module. The DEF source supplies a DEF having a quality factor. The NOx sensor is in fluid communication with the exhaust gas conduit. The NOx sensor is located downstream of the SCR device and is configured for detecting a NOx concentration value. The control module is in communication with the DEF source and the NOx sensor. The control module stores a diagnostic adaptation factor and an expected NOx value. The control module includes a dosing module for determining a controls adaptation factor that is based on a deviation between the NOx concentration value and the expected NOx value. The diagnostic adaptation factor is selectively updated with the controls adaptation factor.

摘要： A control method for monitoring a selective catalytic reduction (“SCR”) device is provided. A control method includes adjusting an existing efficiency threshold based on a dosing adaptation value to determine an efficiency threshold. The dosing adaptation value represents an adjusted value of a supply of reductant based on a determined deviation of a downstream NOx concentration value to an expected NOx concentration. The control method includes comparing the efficiency threshold with a determined efficiency of the SCR device. The control method includes generating a message based on comparing the efficiency threshold with the determined efficiency of the SCR device.

摘要： An engine system includes a correction factor generation module and a boost pressure correction module. The correction factor generation module generates a correction factor based on a first pressure difference, wherein the first pressure difference corresponds to a difference between an intake manifold absolute pressure (MAP) when an engine is on and a barometric pressure. The boost pressure correction module generates a corrected boost pressure based on the MAP when the engine is on, a second pressure difference, and the correction factor, wherein the second pressure difference corresponds to a difference between the MAP when the engine is off and the barometric pressure.
