摘要： An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passageway, and a reduction catalyst disposed within the exhaust passageway. The exhaust system may also have a first sensor located to generate a first signal indicative of an operational parameter of the reduction catalyst, and a second sensor located to generate a second signal indicative of a performance parameter of the reduction catalyst. The exhaust system may further have an injection device located to inject reductant upstream of the reduction catalyst, and a controller in communication with the combustion engine, the first sensor, the second sensor, and the injection device. The controller may be configured to determine a NOX production of the combustion engine, determine an amount of reductant that should be injected based on the NOX production and the first signal, and adjust the amount based on the second signal.

摘要： An after-treatment component detection system may include an exhaust system configured to include an after-treatment component configured to remove one or more constituents of the exhaust gases. The detection system may include an upstream temperature sensor configured to measure temperature upstream from the after-treatment component, a downstream temperature sensor configured to measure temperature downstream from the after-treatment component, and a controller. The controller may be configured to receive signals indicative of upstream temperature measurements from the upstream sensor and signals indicative of downstream temperature measurements from the downstream sensor and determine an upstream rate of temperature change and a downstream rate of temperature change. The controller may also be configured to compare the upstream rate of temperature change to the downstream rate of temperature change and generate a fault if the upstream rate of temperature change and the downstream rate of temperature change differ by less than a predetermined amount.

摘要： An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passage, a reduction catalyst disposed within the exhaust passage, and an injection device configured to inject reductant into the exhaust passage. The exhaust system may also have a sensor configured to generate a signal indicative of a concentration of an exhaust constituent and the reductant, and a controller in communication with the sensor and the injection device. The controller may be configured to make a comparison of a value indicative of a rate of change of the signal for a period of time with a threshold amount, and make a determination of whether the sensor is sensing a concentration of the exhaust constituent or the reductant based on the comparison. The controller may also be configured to adjust operation of the injection device based on the determination.
