摘要： An apparatus, system, and method are disclosed for determining a regeneration cycle thermal ramp. A thermal ramp module estimates a regeneration cycle thermal ramp. A soot content module estimates a soot content for a filter. In one embodiment, an oxygen content module estimates an oxygen gas concentration for the filter. A thermal profile module calculates a thermal profile for the filter as a function of the soot content and the thermal ramp. The thermal profile module may also include the oxygen content in the thermal profile calculation. A test module modifies the regeneration cycle thermal ramp if the thermal profile exceeds a thermal threshold. In one embodiment, a communication module may communicate a warning if the thermal ramp exceeds a warning threshold.

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： An OBD system that diagnoses on board the condition of NOx adsorber catalysts in diesel engines and that relies on existing mass-produced exhaust gas oxygen sensor, also known as lambda sensor, technology, and the following established phenomena. In a reducing environment, typical exhaust gas oxygen (lambda) sensors have different sensitivities to various reductants, with sensitivity decreasing in this order: H2>CO>short-chain hydrocarbons>long-chain hydrocarbons. In the process of regeneration of the NOx adsorber catalyst, the original reductant may evolve into a different reductant species, e.g., via reactions such as a water-gas shift (WGS), a reforming, a partial oxidation, etc. This leads to a difference in exhaust gas oxygen sensor readings between the inlet to the catalyst and outlet from the catalyst. It has been observed in diesel engine testing that the ability of the NOx adsorber catalyst to perform such a reductant evolution is correlative to the catalyst's NOx reduction capability.
摘要翻译：一种OBD系统，用于诊断柴油发动机中NOx吸附剂催化剂的情况，并且依赖于现有的大量生产的废气氧传感器，也称为λ传感器，技术和以下建立的现象。在还原环境中，典型的废气氧（λ）传感器对各种还原剂具有不同的灵敏度，灵敏度依次降低：H 2短链烃>长链烃。在NO x吸附剂催化剂的再生过程中，原来的还原剂可以演化成不同的还原剂物质，例如通过反应如水煤气变换（WGS），重整，部分氧化等。这导致了催化剂入口与催化剂出口之间的排气氧传感器读数差异。在柴油机测试中已经观察到，NOx吸附剂催化剂进行这种还原剂演变的能力与催化剂的NOx还原能力相关。
