| Zusammenfassung: | The present disclosure is directed at a method, system and apparatus that may include an oxidation catalyst, a first sensor positioned upstream of the oxidation catalyst, a second sensor positioned downstream of the oxidation catalyst. The first and second sensors may respond differently to the concentration of NO and NO2. In addition, the first and second sensors may provide signals, which may be received by a processor to determine oxidation catalyst efficiency. |
