METHOD FOR OPERATING A CATALYST |
摘要 |
A method for operating a catalytic converter arranged in the exhaust gas of an internal combustion engine. The composition of exhaust gas being controlled in front of the catalytic converter by adding a reducing agent that promotes the regeneration of the catalytic converter. The composition of the exhaust gas being detected with the aid of an exhaust-gas sensor positioned downstream from the catalytic converter. A time lag between the start of controlling the composition of the exhaust gas in front of the catalytic converter and the detection of a change in the composition after the catalytic converter are evaluated. In order to be able to determine the end of a regeneration phase of the catalytic converter in a safe and reliable manner, the gradient of an output signal of the exhaust-gas sensor is evaluated. |
