    摘要： An internal combustion engine in particular for a motor vehicle is described, which is provided with a storage catalytic converter, which is filled with and emptied of nitrogen oxides. Using the control unit, a plurality of aging conditions of the storage catalytic converter can be determined. Using the control unit, a reversible aging curve and a non-reversible aging curve can be determined from the aging conditions.

    摘要： A method is presented for controlling the supply of reducing agent to a NOx-storage catalytic converter of an internal combustion engine, which is operated at least at times with a lean air/fuel mixture, with an exhaust-gas sensor mounted in flow direction rearward of the NOx-storage catalytic converter; wherein the supply of the reducing agent takes place repeatedly in time intervals separate from each other; and wherein the reducing agent quantity, which is supplied in each time interval, is reduced compared to that quantity which is supplied in a previous supply phase in which a reaction of the exhaust-gas sensor occurred.

    摘要： The disclosure is directed to a method for improving the exhaust-gas quality, which is reduced by sulfur influence, in combustion processes with exhaust-gas catalytic converters. In the method, the oxygen storage capability of the catalytic converter is determined and is compared to a threshold value. When there is a drop below the threshold value, the exhaust-gas temperature is increased and/or an exhaust-gas composition, which acts in a reducing manner, is generated forward of the catalytic converter.

    摘要： A tank venting device for motor vehicles having an internal combustion engine supplied from a fuel tank. The device includes a filter housing, which is connectable to a venting stub of the fuel tank and includes an adsorption filter, whose air inlet is occupied by a shutoff valve and whose air outlet communicates with an intake tube of the engine, and an air feed pump and a diagnosis device. To improve the metering capability for the regeneration mixture aspirated from the filter to the intake tube of the engine, the air feed pump is disposed with a reversible feeding direction between the air outlet of the filter housing and the intake tube of the engine. The air feed pump is controlled in its feeding direction reversal via a multiposition control valve such that the filter housing is located on the intake side of the air feed pump for the duration of filter regeneration, and on the pressure side of the air feed pump for the duration of error diagnosis.

    摘要： The invention is directed to a method for checking the operability of a tank-venting valve which is connected in a venting line of a tank-venting apparatus between the intake pipe of the internal combustion engine and an adsorption filter equipped with a venting line. The tank-venting valve can be driven into two switching states, namely, an open state and a closed state. The method includes the steps of: driving the tank-venting valve to reach one of the two selectable switching states; checking the pressure on the end of the tank-venting valve facing away from the intake pipe and checking whether this pressure exhibits a time-dependent trace as it cannot occur in the desired switching state; and, concluding that a defect in the tank-venting valve is present when the condition checked in the previous step is satisfied. With this method, the operability of a simple tank-venting valve can be reliably checked. The method requires no special mechanical, capacitive or inductive checking arrangement.
