摘要： A method unloads hydrocarbon emissions deposited by an exhaust gas on an after-treatment device that is employed in an exhaust system for an internal combustion engine. The method includes determining whether the engine has been operating at a preset idle speed for a predetermined amount of time. The method also includes increasing the preset idle speed by a predetermined value if the engine has been operating at a preset idle speed for a predetermined amount of time. The increasing of the engine idle speed increases a flow rate of the exhaust gas to the after-treatment device and unloads the deposited hydrocarbon emissions. A system for unloading hydrocarbon emissions deposited on an after-treatment device and a vehicle employing such a system are also disclosed.

摘要： An amount of particulate matter accumulated in a particulate filter of an exhaust system is estimated by preloading a memory location with a plurality of hybrid models. Each hybrid model estimates an amount of particulate matter accumulated in the particulate filter between a pair of operating points. An estimated amount of particulate matter accumulated in the particulate filter is stored in the memory location for each hybrid model. Each hybrid model is ranked based on estimation accuracy during operating conditions and the highest ranked hybrid model is selected. The estimated amount of particulate matter accumulated in the particulate filter corresponding to the highest ranked hybrid model is added to the soot estimation value stored in the memory location that corresponds to a ranked hybrid model to provide a soot estimation value of a cumulative estimated amount of particulate matter contained in the particulate filter for the ranked hybrid model.

摘要： A method of correcting a soot mass estimate in a vehicle exhaust aftertreatment device includes monitoring an exhaust gas pressure drop across a particulate filter included with the vehicle exhaust aftertreatment device. Following the detection of a pressure drop, a controller may determine a soot mass estimate from the monitored pressure drop; determine an ash volume estimate representative of an amount of ash within the particulate filter; determine an ash correction factor from the soot mass estimate and the ash volume estimate; and calculate a corrected soot mass value by multiplying the ash correction factor with the soot mass estimate. If the corrected soot mass value exceeds a threshold, the controller may generate a corresponding particulate filter regeneration request.

摘要： A method for controlling regeneration within an after-treatment component of an engine includes receiving a signal that is responsive to a change in pressure across an after-treatment component and calculating an estimate of accumulated particulate matter in the after-treatment component using a soot accumulation model calibrated to simulate operation of the engine at a reference condition. A soot model correction factor is based at least in part on an environmental temperature correction and is applied to the estimate of accumulated particulate matter in the after-treatment component to produce a temperature-compensated estimate of accumulated particulate matter in the after-treatment component. The temperature-compensated estimate of accumulated particulate matter in the after-treatment component is compared to a predetermined threshold associated with the after-treatment component, and a remedial action is initiated when the temperature-compensated estimate of accumulated particulate matter in the after-treatment component exceeds the predetermined threshold.

摘要： A method of establishing a mass flow rate of air entering an engine includes establishing an input voltage by an energy supply device to energize a mass-air-flow sensor. The method also includes generating an output frequency via the mass-air-flow sensor in response to the mass flow rate of air entering the engine and determining the flow rate using the generated output frequency. The method additionally includes comparing the generated output frequency with a predetermined threshold output frequency that corresponds to the established input voltage. Additionally, the method includes selecting the determined flow rate as the established flow rate if the generated output frequency is at or below the predetermined threshold output frequency. Furthermore, the method includes selecting a predetermined alternative algorithm to generate the established flow rate if the generated output frequency is above the predetermined threshold output frequency. A system for establishing the mass flow rate is also provided.

摘要： An internal combustion engine includes an intake air compressor system and is fluidly coupled to an exhaust aftertreatment system having a particulate filter. A method for operating the internal combustion engine includes determining a total engine-out soot generation based upon a summation of a steady-state engine-out soot generation rate and an engine-out soot generation rate correction. The engine-out soot generation rate correction is either zero when the intake air compressor system is closed-loop controlled or a rate based upon a deviation between an actual boost pressure and an expected boost pressure from the intake air compressor system. The particulate filter is regenerated when the total engine-out soot generation exceeds a predetermined threshold.
