METHOD AND DEVICE FOR DETERMINING THE OXYGEN STORAGE CAPACITY OF THE EXHAUST GAS CATALYTIC CONVERTER OF AN INTERNAL COMBUSTION ENGINE, AND METHOD AND DEVICE FOR DETERMINING A DYNAMIC TIME DURATION FOR EXHAUST GAS PROBES OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>An exhaust gas catalytic converter is laden with oxygen until it is saturated at least upstream of an exhaust gas probe. A predefined first rich air/fuel ration is set in a combustion chamber of a cylinder. A first oxygen storage capacity value is determined as a function of the measurement signal of an exhaust gas probe and the predefined first rich air/fuel ratio. The exhaust gas catalytic converter is laden with oxygen until it is saturated. A predefined second rich air/fuel ration is set in the combustion chamber of the cylinder. A second oxygen storage capacity value is determined as a function of the measurement signal of the exhaust gas probe and the predefined second rich air/fuel ration. A corrected oxygen storage capacity value is determined as a function of the first and second oxygen storage capacity values.</p> |
