| description | A method and device for monitoring the formation of nitrogen dioxide at an oxidation catalytic converter is disclosed. The conversion of the nitrogen oxides, corresponding to a first exhaust gas volume flowrate through the oxidation catalytic converter, is detected. The exhaust gas volume flowrate is then changed and the conversion of the nitrogen oxides which changes with the change in the exhaust gas volume flowrate is also detected. By reference to the respective conversion of the nitrogen oxides at the different exhaust gas flowrates through the oxidation catalytic converter, it is concluded, on the basis of a predetermined relationship between the conversion of the nitrogen oxides and a proportion of nitrogen dioxide in the nitrogen oxides in the exhaust gas, that nitrogen dioxide is being formed at the oxidation catalytic converter. |
