Abstract
An integrated sensor-catalyst is disclosed for an after-treatment (AT) system used to filter an exhaust gas flow emitted by an internal combustion engine. The integrated sensor-catalyst includes a sensor element configured to detect a parameter of the exhaust gas flow. The integrated sensor-catalyst also includes a micro-catalyst element configured to filter a pollutant from the exhaust gas flow. Additionally, the integrated sensor-catalyst includes a housing configured to hold the sensor element and the micro-catalyst element and fix the micro-catalyst element relative to the sensor element such that the micro-catalyst element is arranged and maintained in the exhaust gas flow upstream of the sensor element. A vehicle including such an AT system with the integrated sensor-catalyst is also disclosed.
