    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 and system for adaptively controlling a diesel engine to account for variations in the cetane number of the diesel fuel being used. An engine controller includes various control modules with algorithms for estimating the fuel cetane number, or determining the ignition delay that the engine is experiencing, or both. With this information, the controller can adjust the amount of exhaust gas recirculation that is used, thus varying the amount of oxygen that is available in the intake charge to burn the fuel. The controller can also adjust the timing of the fuel injection event, as another way of altering the nature of combustion. Using these techniques, the controller can optimize the engine operation based on the fuel currently being used.
