Method for determining the nitrogen dioxide concentration in exhaust gases |
| abstract |
In a method for determining an NO 2 concentration and/or a concentration ratio of NO 2 and NO in an exhaust tract of a combustion device, such as an internal combustion engine, an NOx sensor that is sensitive with respect to NO 2 and NO is utilized, which provides a NOx output signal correlating with an NOx concentration representing the sum of the concentrations of NO 2 and NO. In order to determine the NO 2 concentration and/or the concentration ratio of NO 2 and NO, the NOx output signal of a first NOx sensor, which is arranged upstream of an exhaust gas treatment element arranged in the exhaust tract and having the capability of converting NO to NO 2 and/or converting NO 2 to NO, is compared to the NOx output signal of a second NOx sensor, which is disposed downstream of the exhaust gas treatment element. |
