  "textContent": "The method involves verifying the functional capability of nitrogen oxide that is an oxidation catalyst (5). A defined amount of carbon monoxide is added as a reducing agent. Carbon monoxide is oxidized with the exhaust gas stream upstream of the nitrogen oxide oxidation catalyst. Actual value of oxygen is closed by the oxygen set point to an impaired functioning of the nitrogen oxide oxidation catalyst, at a defined deviation. An independent claim is included for an apparatus for performing the method to check the operation, particularly oxidation ability of the exhaust line in an internal combustion engine.",
