摘要： A system, method, and software that rapidly heats a diesel oxidation catalyst unit to an effective operating temperature at engine startup is disclosed. Upon ignition of an engine an electronic control unit is operable to lower a fresh air flow target value to a reduced fresh air flow target value as well as lower a valve opening limit of an exhaust gas recirculation valve to a reduced valve opening limit. The electronic control unit monitors a temperature value of a flow of exhaust entering the diesel oxidation catalyst unit until the temperature value reaches a first predetermined threshold value. After reaching the first predetermined threshold value, the electronic control unit causes the fuel system to set post-injection fueling to a predetermined post-injection fueling value until the temperature value of the flow of exhaust entering the diesel oxidation catalyst unit reaches a second predetermined threshold value.

摘要： A system and method are provided for controlling regeneration of exhaust gas aftertreatment components coupled to an internal combustion engine. For example, the particulate load of a particulate filter is monitored and a road speed of the vehicle is determined. If the particulate load is greater than a particulate load threshold and the road speed is greater than a road speed threshold, regeneration of the particulate filter is initiated. As another example, the sulfur oxide load (SOx) of a NOx catalyst is also monitored, and if the SOx load is greater than a SOx threshold while the particulate filter is being regenerated, regeneration of the particulate filter is terminated and SOx regeneration of the NOx catalyst is initiated.

摘要： A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. An exhaust sulfur flow rate module estimates a sulfur accumulation rate associated with an adsorber as a function of a flow of fuel. A sulfur removal rate module estimates a sulfur removal rate associated with the adsorber. An accumulated sulfur loading module includes a counter the value of which is increased as a function of the sulfur accumulation rate and decreased as a function of the sulfur removal rate. A combustion manager module controls an engine to regenerate the adsorber once the counter reaches an upper threshold value.

摘要： A NOx adsorber catalyst may comprise a housing defining an inlet configured to receive exhaust gas produced by an internal combustion engine, an outlet and a chamber between the inlet and the outlet. A NOx adsorber element may be positioned in the chamber adjacent to the inlet. The NOx adsorber element may be configured to trap NOx in the exhaust gas during lean fuel operation of the engine, and to release the trapped NOx and reduce the released NOx to nitrogen during rich fuel operation of the engine. A hydrocarbon trap may be positioned in the chamber between the NOx adsorber element and the outlet. The hydrocarbon trap may be configured to trap hydrocarbons that travel through the NOx adsorber element during the rich fuel operation of the engine. The trapped hydrocarbons may be oxidized by oxygen present in the exhaust gas during lean fuel operation following rich fuel operation.

摘要： A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. A sulfur loading estimate module is used to generate an estimated sulfur loading value associated with an adsorber. A desulfation trigger module is used to trigger a desulfation event for the adsorber upon detection of a trigger event comprising either a cost-effective trigger event, a loading trigger event, and a forced trigger event. A combustion manager module is used to control an engine through engine management to regenerate the adsorber during the desulfation event. A interrupt module is used to interrupt the desulfation event upon detection of an interrupt event. An end desulfation module is used to stop or end the desulfation event upon detection of an end desulfation event.

摘要： A method for modifying a NOx adsorber regeneration triggering variable. Engine operating conditions are monitored until the regeneration triggering variable is met. The adsorber is regenerated and the adsorbtion efficiency of the adsorber is subsequently determined. The regeneration triggering variable is modified to correspond with the decline in adsorber efficiency. The adsorber efficiency may be determined using an empirically predetermined set of values or by using a pair of oxygen sensors to determine the oxygen response delay across the sensors.
