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 apparatus and method of controlling a vehicle aftertreatment system is provided. The aftertreatment system treats exhaust gas produced by the vehicle engine and includes a particulate filter, and a NOx reducing device such as a selective catalytic reduction (SCR) device. The particulate filter is configured to regenerate to remove accumulated particles when the exhaust gas is heated above a regeneration temperature. A diagnostic device is included for monitoring the aftertreatment system. The diagnostic device may be a sensor for measuring the oxides of nitrogen (NOx) and/or an SCR efficiency monitor. A controller is employed to optimize the function of the diagnostic device. The controller does not enable the diagnostic device when the vehicle is powered until one or more entry conditions are satisfied.
