    Abstract: 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.

    Abstract: In a method for the control of the supplied air/fuel ratio of an internal combustion engine (1) with a catalytic converter (5) which is located in the exhaust gas line (2) with an integrated oxygen reservoir (6), it is suggested that the air/fuel ratio be controlled as a function of at least one parameter of the internal combustion engine (1), at least one parameter of the catalytic converter (5), and/or as a function of the type and amount of the exhaust gas emissions currently occurring, in order to optimize the speed for adjustment of the admission or discharge of oxygen in the oxygen reservoir (6) contained in the catalytic converter (5) for favorable conversion of the exhaust gas emissions during transient operation of the internal combustion engine (1) and after deviations from the air/fuel ratio λ=1. As claimed in the invention, a “disturbance” of the exhaust gas composition which occurs during transient operation of the internal combustion engine (1) is corrected with a speed which takes into account both the current conversion demand by the catalytic converter (5) and also the current conversion performance of the catalytic converter (5) and thus makes possible improved overall exhaust gas conversion.

    Abstract: An exhaust gas purifying apparatus for an internal combustion engine having an exhaust system. The exhaust gas purifying apparatus includes a NOx purifying device provided in the exhaust system for purifying NOx in exhaust gases, and a temperature sensor for detecting a temperature of the NOx purifying device. The NOx purifying device has NOx adsorbing capacity and generates ammonia and retains the generated ammonia when the air-fuel ratio is set to a value on the rich side with respect to the stoichiometric ratio. The NOx purifying device purifies NOx with the retained ammonia when the air-fuel ratio is set to a value on a lean side with respect to the stoichiometric ratio. The air-fuel ratio is enriched to a value on the rich side with respect to the stoichiometric ratio so as to increase an amount of reducing components in the exhaust gases flowing into the NOx purifying device.
